"pretty bad"?!?!? it looks like it's been dragged through a knothole. backwards. twice. 😃 it's good to be back. i was in the hospital for a while. nothing serious, but needed intense treatment. it's nice to come home and see a couple of videos from you. cheers!
you may want to consider adding a 60~75 Watt soldering pencil/gun to your kit for soldering RF modulator lugs. those bad boys are natural heat sinks and you need a lot of "oomph" to solder them into place. and most/many
Hi John. Firstly, thank you for the coffee 😊. I think my iron is 60W but boy does it struggle with the RF lugs, even when turned right up it still struggles. It's fine with the likes of the DC jack so the large ground planes it doesn't struggle. But those RF boxes.... 😢 I have found that using the iron and a heat gun does work really well, but you need the be an octopus 😂 You're right though. It's like having a lump and ignoring it, pretending it will just go away. I've added it to my list of things that would be useful. I am trying to save up though and get an overhead microscope. I'd sooner struggle a bit with these occasional beefy solder jobs but have better video content overall. I'd like to be able to have those really nice closeup shots like you see on all the popular repair channels
Can't wait for part 2. I'm curious as to how much you paid for this Spectrum considering the poor state it was in? Wishing you a Happy New Year and looking forward to lots more videos.
Hey John. Thanks for that. I can't actually remember how much I paid. I'll find out and include it in part 2. Thanks for your support, it's appreciated more than you realise. Happy New year 🎉
Boy, you're a masochist... The powdery white oxidation pattern on the aluminum keyboard plate and the bit inside the machine plus the way the screws have turned into lumps of iron oxide leads me to believe that it's been stored somewhere with a saline sea-breeze. Maybe an open garage or on a porch somewhere very near the seaside. I see this fairly commonly with machines that I rescue from people's garages here in Florida. With Phillips screw heads that have corroded that badly, occasionally you can get a square tip (Robertson) to fit in past the rotted off edges of the cruciform part of the Phillips and go in far enough to bite. But Yuck!!! That's nasty. I'll be looking forward to part 2 to see if you can get it going.
Thanks Dennis. I appreciate the comment. I thought I'd buy it on the basis it would make for an interesting repair 😁. I think you're absolutely right though. This has been stored somewhere very damp for a long time. I've never seen the case screws rust on the Speccy. I genuinely thought I'd bagged myself an issue one. I couldn't believe how bad they keys had faded. I didn't even know they could fade 😆

Hey John. Glad you're doing well. I was wondering where you'd got to 😊
Looking forward to part 2. Happy New Year and all the best in 2024
Thanks Rudy. All the best for 2024
haopy new year simon
glad to be a part of your channel...
Hey Mike. Happy New Year. Thank you so much for your support. Looking forward to fixing (or breaking) some more old 'vintage' stuff in 2024 😂
18min to take it apart, 10 min rambling, 23 min to change an rf module - it's a good thing it isn't your professional job :)
Haha true

Also remove the heat sink and replace the 7805 with a TSR-1 2450 which runs cool to the touch.
Hi, thanks for the comment. Yes that's a good thing to do. It's on my list for part 2 😊
