I loved your video! ZX Spectrum 48K + was my first computer. So it was why I entered this magical world of computers! I admire your knowledge of these machines. I wish I knew to do that. I almost felt that you loved its hardware and brought it back to life in such a way! Fantastic! :)
Always entertaining. I have mixed feelings about doing a wholesale recap of old electronics. One part of me says replace because the caps are old, another part says don’t screw with something that’s working.
Your theme tune (Sorry, Adrian) is on a loop when I go to bed. It's soothing, jazz-funky and helps me get to sleep. EDIT: I should add that it's never the content that makes me feel sleepy.. Investronica.. siesta.. toast rack... AY zzzz.. woken up now for innuendo watch between you and Mark Fixes Stuff 🙂
It's amazing to me how that Heritage TV Spot on the CBC about brain surgery (epilepsy, not a stroke) has spread th-cam.com/video/pUOG2g4hj8s/w-d-xo.html
Have to agree. I would perform if possible, a close visual check on the caps for leakage. If there is none, or zero signs of swelling, I’m leaving it. Particularly if it’s working!
For some odd reason I feelt slightly depressed when watching the section where you clean and put back together, because the 80s game music playing in the background reminds me of a much simpler time when hearing such music meant fun.
Was it just me that cringed at the reassembly when using a powered screwdriver without backing out the screws as to avoid cutting new threads in the 40-year-old plastic? I spotted at least once screw crossthreading/cutting new threads.
Same. I am not that type who thinks that things can only be done only one specific way, but since these battery powered screwdrivers appeared, everybody uses them like it was the world's largest problem to screw in a few screws by hand - especially into our beloved old and fragile computer cases...
if u replaced the 7805 regulator with a new one then the external heatsink is not going to get hot and you lose certain retro feeling,also on cold days you won't warm your right hand either, and ur 128k will not be a toast rack aymore, bad bad idea
I actually agree but I'd probably recap a sinclair toast rack 128 as a matter of course if one came to me for repair (unlikely these days as I don't do that anymore), they have a tendency to be unreliable. Not in every case but definitely more than enough for me to just say "f*ck it, ill do the whole thing" to save myself a headache later.
I genuinely don't understand why these is this fascination with replacing linear regulators with switchmode ones. You can end up with noise on the board from the switching and the power saving is pointless, you aren't going to be running this machine more than a few hours here and there. It isn't going to be on constantly. Why replace when the OG works well.
I respect videographers that report failures more than the ones who only show successes.
Especially when the error leads to actual damage!
@@richardblake8275 good point

My childhood computer. Will turn 40 years in 2025 (mine was the Spanish). Great video!

Not many know the hippopotamus oath! I love it.

Great shot mate, I have a +2 and just got a hold of a Currah microspeach to play about with.
"Can you smell burning toast?" Are you having a stroke ? ;-) !!
Came here to ask that! 🤣

Recapping just for the sake of it can cause more problems than it fixes. If it 'aint broke, don't fix it.

What’s the point of using an eraser on the edge connector then to rub greasy mitts on it. 😂
I had one of these from new because I was told the graphics and sound were better on the 128, yes I didn't have it long

My friends house burnt down from a spectrum 48k that overheated back in the early 1990s.
Does the new voltage chopper maybe require an extra cap?

I’m not videographist, they all deserve the same level of respect.
80's tech:
"Dirty... I'll wash it in the sink."
20xx tech:
"Does not work... I might be holding it wrong or maybe my breath was too moist."
have you ever worked in radio? because you've got one of the all time great radio voices.
These are always so satisfying! Esp a new keyboard membrane
"Burning toast"? I mean, with 128, that's not quite nominative determinism, but it's not far off!

:D cool
What is the music from, when you are cleaning the parts? 8:04 I recognise it from somewhere but I can't put my finger on it.
Nice vid mate.
Same, took me ages... Sayaka's Digital Attic ;)
@@charlesdorval394 I think she has just used it from somewhere. I think it may be an old game.
Great clean and repair but the heatsink have no function to get heat.
Invest in an ESD dissipative mat.
But... I toast, therefore I am! 🍞😋👍
I gotta say, your new intro and logo has grown on me.
That said, I don't believe in compulsive recapping.
Oh yeah pop that cap
Z80 CPU have only just been discontinued.
Recapping & modifying vintage computers that don't need it is getting to be a pet hate.

Or at least supplement the switching supply with a beefy cap to at least lessen the high frequency noise.
Always better to replace old caps most are way out of spec.
trum
the music is SOOOO LOUD! An went on FOREVER! The 8-bit noise was making want to destroy things to make it stop
So sad you don't have volume control 😢
