https://makertube.net/videos/watch/1ef0ac66-e5b4-456b-af9e-5dc4b1d2b6df Special thanks to PCBWay for sponsoring this video. https://www.pcbway.com/ Today I tackle a dead ZX Spectrum from a huge box of retro repairs. Watch as I diagnose the faults, replace a blown transistor, and perform a composite mod to bring it back to life—along with a slight detour after accidentally frying a few 74LS157 logic chips with reverse polarity! Proof that we all still learn from our mistakes on the bench. ───────────────────────────── If you'd like to help keep the lights on (and the tools plugged in), my Patreon is the best way to do it. Patrons get ad-free early access to videos, behind-the-scenes updates, and entry to a super secret Discord channel — plus my sincere gratitude, which is worth roughly what you'd expect. ▸ Patreon: https://www.patreon.com/c/morefunmakingit ───────────────────────────── I also have another channel called More Fun Making It, where I build things from scratch instead of trying to coax life back into them. Same shed, different end of the workbench. ▸ More Fun Making It: https://www.youtube.com/@morefunmakingit ───────────────────────────── There's also the Retro Hardware Discord, where people who enjoy this sort of thing gather to talk about it. It's better than it has any right to be. ▸ Retro Hardware Discord: https://discord.gg/ChH726tbbF ───────────────────────────── #ZXSpectrum #RetroComputing #ElectronicsRepair Tue, 26 May 2026 18:04:28 GMT https://validator.w3.org/feed/docs/rss2.html PeerTube - https://video.gamerstavern.online https://video.gamerstavern.online/lazy-static/avatars/41e1d69d-a9bf-455c-9246-5a7a5dacf7c4.png https://makertube.net/videos/watch/1ef0ac66-e5b4-456b-af9e-5dc4b1d2b6df All rights reserved, unless otherwise specified in the terms specified at https://video.gamerstavern.online/about and potential licenses granted by each content's rightholder. https://video.gamerstavern.online/w/4PAyEj5J1WoYNAUugRV7Mv;threadId=31319 https://video.gamerstavern.online/w/4PAyEj5J1WoYNAUugRV7Mv;threadId=31319 Sun, 24 May 2026 12:00:21 GMT Now I am positive you won't do that again!
