Ah, the fabled crispy banded resistor. If you consult the "Exotic Resistor Manual Volume 2 Revision 3 Sub-revision 7" you will find that a crispy band on a resistor indicates a resistance of anywhere between 0 ohms and into the hundreds of meg-ohms. You need to compare the darkness of the crispy band against the official chart to know the value. Alternatively, one can employ the use of a multi-meter, however, the ERMV2R3SR7 does caution against taking such extreme measures.
@@MoreFunMakingIt Well, TH-cam isn't wrong for suspecting me of spam. I don't have any in the house, but I certainly could. TH-cam is just being cautious.
Well I guess the whole thing is the result of extraordinary talent, a 400+ °C ...hot iron from the car workshop, and... long term storage under a cottage on the beach? Great job on the videos!
for knackered sockets like that i find cutting them into strips of 4 pins and using a clamp and hot air from the other side to get them out in pieces, then desoldering braid to clear the holes. loving the dedication on this beast of a board.
On holiday on the Scilly isles and this video is a terrific was to recover from exposure from the wind, rain, sea spray and sun! Very enjoyable video Lee, looking forward to the next episode!
Found your channel through RMC and going through your back catalogue as it were! Watching this while I'm working, and I couldn't believe the repair of a perfectly working trace at 25:30 ! Who does that?
26:35 this is a good case for enamelled wire. You could pass that through the via, down through the socket hole, and then off to wherever else the trace connected to... and solder at all points. The enamel insulates it but would burn away where you make the solder joints. I recycled a lot of mine from old CRT deflection coils and deguass coils continuing to watch with much interest!
@@MoreFunMakingIt Lovely, thank You. I'm binge watching all the videos of this repair (and other videos of yours). Incredible but instructional and entertaining this repair. Great job Sir.
Excellent job Lee! I've watched all the episodes, for some reason watching this one last. I can't believe all the mess under the ICs. Very enjoyable video series.
Quite amazing to see the evolutions of your knowledge and understanding in the experiences you've shared. Guided is one thing, but you've took the tools, resources and time and made your own style, work and system. Something as bad as this really highlights that journey! Look forward to Pt 2 😊
I couldn’t help but laugh at the humour and even I, a complete non electrical person, could see that you have a real multi part project here. Now time for me to get back to my fine, precise, delicate brain surgery with my blunt hedge trimmer.
That's a ZX Dandanator. They're a bit tricky to get hold of, the licence doesn't allow selling of them so you need to either make one yourself or get someone else to make it. Probably easier to buy a dedicated diagnostic cart. They're not too expensive on eBay.
I have a family spectrum 48k with a output from the modulator that is black and white and distorted. Should I replace the modulator? Replace caps that are in it?
Modulator is probably fine. If it's a modern TV it's probably just struggling to tune in. The best thing to do is convert it to composite instead. Then if the picture is still bad you know you have a problem
Whoever it was that attacked that poor Speccy with a blowtorch makes me feel so much better about my own soldering skills, so I guess that's something. At least it's in the best possible hands now. 🙂 Can't wait for part 2!
It's really hard to know what happened to it. I'm sure it was worked on by multiple people, some of the work is reasonable. But someone got themselves into a mess, and instead of stopping and getting help they just went wild. Part 2 is well under way!
Just started watching this series.. im sure it's going to be "fun" :) Just so you know, the ZTX313 is not critical for the spider mod. A BC546 will work just fine
In fact, most of the transistors in the Spectrum are not critical. The only exception really is the ZTX650 in the voltage converter circuit - ZTX653 is still made (just has a higher voltage rating) and is the only real replacement there. ZTX 313 and BC184 can be replaced by BC546. ZTX213 likewise by a BC556. The ZTX450 seen driving the speaker can be replaced with a BC337-40. Watch for different pinouts.
That’s very very bad! You did a already incredible job to this point, and I still don’t get it for these wires and not needed repairs. Seriously what the heck ? 😅😂
Yup! There's so much more wrong with it, you'll see in the next 2 episodes. Some of the things... You might see one in a bodged repair, but all of them is just bizarre.
by the looks of that spider mod, it looks like whoever did that mod wanted the benefits of a socket with the troubles of being soldered directly onto the board
Always be careful when resurrecting an old Spectrum from death. You never know what it is going to do. I have seen documentaries on television where humans were brought back to life and some of them had cravings for the flesh of healthy good looking teenagers. If a Spectrum is resurrected then maybe it starts cannibalizing other computers, laptops and tablets.
Looks like one of mine... Tbh the way that board disintegrates has made me worry about the recap I'm about to attempt on my ish2! Amazing how b0rked a board can be while still looking reasonable from a cursory glance.
They're so fragile. A good way to learn how to desolder super carefully! You should be fine with a recap. Watch for some of the holes in the heavy ground sections being tough to clear. You can always follow that solder and poke the leg of the new cap into the hole. Good luck!
I have 13 hours of raw footage that's just like this, except without the funny bits and special effects, and with a lot more "old man talking to himself and breaking wind" Maybe I should have that as a Patreon perk 🤔🤣
@@MoreFunMakingIt a whole second channel with just the raw footage uncut would be epic. I would definitely watch atleast. Could call it "More Fun Making It Raw". 😆
Maybe that's something I would do in the future. Its still a lot of work, I'd still have to go through and make sure there were no personal details shown by accident etc.

He does have a very calming voice. Like an educational presenter from the 70's.
Never solder after 9 pints of cider. That seems to be the lesson here.

But I agree with the likely toolset.

I just channeled my inner "grumpy old man" which also happens to be my outer persona 😜
for knackered sockets like that i find cutting them into strips of 4 pins and using a clamp and hot air from the other side to get them out in pieces, then desoldering braid to clear the holes. loving the dedication on this beast of a board.
Before I got the desolder station I used the same method you mentored.
Now I love an excuse to moo a part off the board 🤣
Wow.. just shocking but I'm totally riveted to it. Can't wait to see the next!

I think this was one of those "seemed like a good idea at the time" occasions.
I'm reminded of the Simpsons episode where Sideshow Bob takes a rake to the face every time he takes a step.
Soooo many rakes. In later episodes you'll see some I put there myself!
Ooooh, a cliffhanger!
