And the image is very stable, probably helped by those new capacitors. It does start to drift a little over time, as components heat up, but we'll see what we can do about that when that replacement diode is in place and the whole board is fully working. One thing we do notice though, is that one of the paddles doesn't have nearly enough range any more and is only able to move the bats a few inches at the top of the screen. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/1716046036539-M0NNF4U6PIK6JL77I71E/IMG_3445.JPG Repairs, Refurbs & Mods - Conic TVG 201-4 - Had no chance of removing the screw normally & couldn't drill it out either, so we've broken the plastic surround a little to get the case apart. Shame, but pretty small collateral damage given the state of things.

And the paddle jacks came up nice and shiny after some scrubbing too. We're very pleased with how this is looking now. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/1716046073139-N3CX5VTX6HTKOPAVFK0C/IMG_6289.png Repairs, Refurbs & Mods - Conic TVG 201-4 Lovely https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/1716046027560-6GAPLJIZ1CAE05ECZ8VT/IMG_3451.JPG Repairs, Refurbs & Mods - Conic TVG 201-4 - There we go, board is out. Switches are rusty, as is the box shield over the RF circuitry. Everything else is just dirt though. The labels and plastic button caps look pretty good. There we go, board is out.

We cleaned the marks off with a wet "magic sponge", squirted contact cleaner into the potentiometers and rubbed platen cleaner along the wire and the jack surround at the end, to treat all the soft plastic and prevent it from cracking. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/1716046036485-NRGL6SMBN778SD6D8APO/IMG_6199.JPG Repairs, Refurbs & Mods - Conic TVG 201-4 - Meanwhile, we still need to find out whether the chip and the rest of the board work when pin 4 has it's requisite 9V supply. So we bypass the upstream circuit and patch the chip straight to the positive side of the power switch... https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/1716046121540-MVRS8RZDCNOOPSSRN43S/IMG_6261.png Repairs, Refurbs & Mods - Conic TVG 201-4 - Flynnie solders in the replacement Zener diode, but the board still doesn't work when we remove the patch lead. (We were experimenting with using a Dremel gas iron. Turned out to not be a good idea at all, on another project…) https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/1716045755620-TZG7EMRQE3F9FUHPY0MV/IMG_6282.png Repairs, Refurbs & Mods - Conic TVG 201-4 - Everything's now done on the main unit, so it's time to close up. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/1716046034546-THOUT5C5QLAQWHFQVK2J/IMG_6167.JPG Repairs, Refurbs & Mods - Conic TVG 201-4 - Time to return our attention to the board and why it's not working. It was very quickly apparent that the AY chip was not getting the 9V on pin 4 that it should be. The switch is ok, so it must be something between the switch and the chip, and there are only three components it could be: the zener diode in the photo, the resister next to it and the transistor you can just see in the bottom right. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/f865be9a-cf07-4678-bcff-6baf4206e780/IMG_3411.JPG Repairs, Refurbs & Mods - Conic TVG 201-4 - First look inside the battery compartment and it's epically bad. Still, let's see how much of the hardware we can rescue. .. The biggest issues are probably the screws that hold the case together. They look very far gone. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/1716046022662-CAKPX142WXISJ2955LB0/IMG_3415.JPG Repairs, Refurbs & Mods - Conic TVG 201-4 - There's what remains of a screw in there somewhere. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/1716045773199-CHVX3HGQSVA073PLBN6X/IMG_6285.png Repairs, Refurbs & Mods - Conic TVG 201-4 - I was really struggling to clean the plate, when I realised it still had the protective film on it! If this console was rarer and in mint condition, I would definitely keep the film on, but in this case it's like finding an extra upgrade! https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/1716045853967-WB7F1NQVB7R071OZP28Z/IMG_3450.JPG Repairs, Refurbs & Mods - Conic TVG 201-4 - Next thing is to get through those rusty screws to separate the main board from the case - how bad is it inside?

Should probably have checked it in the first place! https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/1716046074464-AI1V5BV33U9HDJURMA7D/IMG_6290.png Repairs, Refurbs & Mods - Conic TVG 201-4 - Jubbly https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/1716046029186-WU30UBOTVIVYVFFLQDF7/IMG_3811.JPG Repairs, Refurbs & Mods - Conic TVG 201-4 - There we go, with all that corroded metal and acid cleaned out, and the replacement contacts in place, we're starting to get somewhere. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/1716046057040-H8AQMAWRWR0W67JI7FWV/IMG_6287.png Repairs, Refurbs & Mods - Conic TVG 201-4 - All back together and time for a test. This is always the most nerve wracking one - worst than the first 'moment of truth'. So many times we've had a unit that just stops working at this point, after we've put it all back together. Luckily this time not only does it work perfectly, but the paddle with the broken potentiometer seems to have miraculously healed itself! Maybe all that contact cleaner we used did work it's magic after all. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/1716045843333-H410HL09EY9VPYU0F92K/IMG_3408.JPG Repairs, Refurbs & Mods - Conic TVG 201-4 - This is the machine as it arrived. We paid £5 for it in July 2019. The listing explained that it had severe battery leakage, and we can see the discolouration to the outer case, so we know it's going to be pretty bad... https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/1716046106320-BMGXRXI90PYBL5ZGDCZF/IMG_6306.png Repairs, Refurbs & Mods - Conic TVG 201-4 - Beautiful! https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/1716045846091-HEA9QL2NC4FU8LBE9TX6/IMG_6270.PNG Repairs, Refurbs & Mods - Conic TVG 201-4 - Here it is. A bit of digging and I discover a data sheet for it - a standard 2N2222 should be a suitable replacement. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/1716046155482-0XR73E0XRI3XEAYOUF3D/IMG_6286.png Repairs, Refurbs & Mods - Conic TVG 201-4 - Looks much better. I'm also leaving this plate loose, so we can easily remove it and move the slider down past the point that the cutout allows, to the hidden 'handicap' game modes. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/1716046101108-WJKB4PH1MKTB3WY6BQ9Y/IMG_6293.png Repairs, Refurbs & Mods - Conic TVG 201-4 - Pretty pleased with how clean the battery compartment turned out. And yes it does work with batteries in! https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/1716046034673-A9P2Y8BZ3L2YTXUMZ264/IMG_6182.JPG Repairs, Refurbs & Mods - Conic TVG 201-4 - We strip the potentiometer on the offending paddle, to see if there's anything obviously damaged and give it a thorough clean, but it doesn't help - the range is a fraction of what it should be when compared to the other paddle using the multimeter to measure their respective resistances. So we order a replacement pot. 24mm base, 20mm shaft, Linear B 500kOhm - hopefully it will fit right into the paddle just like the old one. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/bedf6419-8e04-4e7b-b1c8-85eb34a7e5ac/IMG_3410.JPG Repairs, Refurbs & Mods - Conic TVG 201-4 - The paddles seem OK, if dirty and marked. Most importantly the knobs are present - we probably wouldn't have bought it if the knobs were missing. Or if anything else was actually missing, for that matter. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/73bc5d8f-dc74-42ea-bb8d-499bc000f8e0/IMG_3412.JPG Repairs, Refurbs & Mods - Conic TVG 201-4 - Pretty grim. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/1716046027398-7UVVJ7JQ9FVQJKZJU2O5/IMG_3808.JPG Repairs, Refurbs & Mods - Conic TVG 201-4 - Several hours of cleaning later, and with the two electrolytic capacitors replaced, the board is starting to look OK. However, it doesn't work - we connected a 9V supply but the board makes no sound and there's no picture to tune in to. We'll have to come back to this to figure out what's wrong later.

You can't see it very well here, but we also bound vinegar-soaked kitchen towel around the paddle jack ends to de-oxidise the metal pins, and wrapped them with gaffer tape. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/09711b6b-2a85-4d02-a68c-2ec906c8601c/IMG_4971.jpg Repairs, Refurbs & Mods - Conic TVG 201-4 - The only thing that's suffered is the paper label on the top cover. We've tried to protect it, but it's not easy when it's undergoing so much cleaning. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/1716046025105-S53PDTH4KH5CI8OWWYRO/IMG_3448.JPG Repairs, Refurbs & Mods - Conic TVG 201-4 - With all the battery hardware removed, we're now trying to save as much of the original metal as possible by soaking it in vinegar. Maybe that spring can be re-used? Or the screws at least? Some of the metal just disintegrated in our fingers, though.

And the sheared screw is going to have to stay like that - 3 screws should be enough to hold it together, anyway. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/1716046055915-GNURAFHALJY2YQ9TREHV/IMG_6288.png Repairs, Refurbs & Mods - Conic TVG 201-4 - All done!

We remove it from the board in order to test it with the component tester, but before we can do that one of the legs just falls out of the diode. Luckily we can see from the markings that it's a BZX 79C 6V8, so we order a replacement. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/1716046089486-J0VKF3V2WLW63D7APRN8/IMG_6291.png Repairs, Refurbs & Mods - Conic TVG 201-4 - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://www.deadfleshretro.com/refurbs/acorn-electron-001 monthly 0.5 2024-06-02 https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/e329d520-53c3-4c10-88e1-a689039be79b/IMG_8649.JPG Repairs, Refurbs & Mods - Acorn Electron #001 - Back on go the keys.

As long as the keyboard is connected, that is. There was a fair bit of child-safe swearing before we figured that out. Great puddles of poo! https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/bc6ef54b-583f-4b11-8cb6-0e76d310e83b/IMG_8647.JPG Repairs, Refurbs & Mods - Acorn Electron #001 - And likewise with the keyboard, although more on this later... https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/27fc9d42-dc8a-46aa-b84e-1cc3de3c2800/IMG_8908.JPG Repairs, Refurbs & Mods - Acorn Electron #001 - The Electron came with a few games and manuals, and so, once we’d bought and refurbished an appropriate tape deck, Flynn and I attepted to load Meteors. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/fb4f4295-4da6-445c-9eaa-bdc3154bd055/IMG_8499.JPG Repairs, Refurbs & Mods - Acorn Electron #001 - We thought it would be best to take it apart and clean it before trying to switch it on. (Nowadays, I’d almost certainly see if there’s any life straight away!) https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/3004b6b6-c712-43ad-a3e6-d95456e94d5f/IMG_8622.JPG Repairs, Refurbs & Mods - Acorn Electron #001 - The next thing we wanted to try out, before putting it all back together again, was retrobrighting to reverse the yellowing the plastic case and keys had experienced with age. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/41baa17c-71ea-408a-a785-eca399cc8326/IMG_8539.JPG Repairs, Refurbs & Mods - Acorn Electron #001 - Much better! https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/8956feb1-da55-44f4-9249-ae76d0318633/IMG_8934.JPG Repairs, Refurbs & Mods - Acorn Electron #001 - There is some configuration required, and I had to learn about the various disk formats that were available for these machines, as well as how expansion ROMs work, but the documentation is good and everything worked exactly as advertised. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/9ff26e95-42a9-4b3b-9a6d-48024b259349/IMG_8681.JPG Repairs, Refurbs & Mods - Acorn Electron #001 - And a final test to make sure it still all works, and all the keys register correctly. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/c9fa4724-9514-4449-bbf9-75a2b713a283/IMG_8538.JPG Repairs, Refurbs & Mods - Acorn Electron #001 - Flynn learned how to test for continuity by following the power rail around the board. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/1715448627262-XQ7PXBLLZOQMZ7BAC4ZA/IMG_8493.JPG Repairs, Refurbs & Mods - Acorn Electron #001 - Flynn really enjoyed taking the little machine out of its packaging (and getting inside it!), and liked the tactile keyboard straight away. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/82244a31-8d4a-4287-981f-40cdd4d0c06d/IMG_8505.JPG Repairs, Refurbs & Mods - Acorn Electron #001 - All the components are out of the case and ready for cleaning and testing. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/afe34c4f-7382-4a48-8dea-eb889a44a2e7/IMG_8536.JPG Repairs, Refurbs & Mods - Acorn Electron #001 - Pretty grotty… https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/bcfd360a-5bca-4fab-8050-343e2198e4f1/IMG_8545.JPG Repairs, Refurbs & Mods - Acorn Electron #001 - Now we need to clean all the keys with a toothbrush in warm soapy water. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/e107bb49-b42e-44ac-acdb-a999ba2c05cf/IMG_8542.JPG Repairs, Refurbs & Mods - Acorn Electron #001 - Time consuming but also quite therapeutic. Flynnie wasn’t having any of it though. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/1715449062565-48FWEF7YLZUKVZZWQJYU/IMG_8660.jpg Repairs, Refurbs & Mods - Acorn Electron #001 - And here’s it is all cleaned up https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/bcc9547b-7f21-4fca-a0e0-5aca1c71a688/IMG_8660.jpg Repairs, Refurbs & Mods - Acorn Electron #001 - And here’s the Electron as it came out of the box. I bit dirty, but in very good condition. https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/45837472-bc56-4995-8d20-a16b28d087c6/IMG_8645.JPG Repairs, Refurbs & Mods - Acorn Electron #001 - Before putting it all back together, I added a jumper across link LK4, which is adds a colour signal to the Electron’s composite output (I have no idea why that isn’t the default - did that many people have black and white TVs in 1983?) https://images.squarespace-cdn.com/content/v1/663fa51eeccf3f21073f803b/91dc4c92-9b43-4e78-a34b-c4bc9a2e7a76/IMG_8501.JPG Repairs, Refurbs & Mods - Acorn Electron #001 - It was genuinely exciting to see the famous Ferranti ULA in it’s little metal cage.
