Spectrum + and +3 Bath! Including SEXY photos!
Continuing my "bath" projects:
Today I repaired a 48K Spectrum + to working condition, an Issue 4 that is nice and stable.
Took 4x Spectrums+ apart and selected the best covers & keys to build one machine that looks great.
The +3 is the only one I have, so everything got the scrub down to be reassembled again.
Someone said when they bath their Spectrums, they take out all the keys and give these individual treatment. I did this with the Spectrum + and having 4x machines laying about in bits, was considerable more work, but hopefully worth it.
The 128k toastrack version is ? finished. Should be finished tomorrow. Pictures are at the end.
Todays completed Spectrums:
Spectrum+ and the +3
The usual bath treatment then coating with that German car cleaner liquid.
Great logo!
Lovely shiny keys
Various close up shots
Unfortunately the "3" has seen better days. Close up shots really show flaws, that is otherwise not really noticeable....thankfully.
These shots are taken close up and full flash through the grating on the case.
This shows the PCB and connections, how they look whilst INSIDE the machine.
This shot, of the Spectrum+, shows how the membrane is aligned inside the machine
The 128K toastrack machine, awaiting assembly and polishing tomorrow.
So far its just had its bath
Here is the PCB, version 6U (never heard of such a version)
I mounted the blue heatsinks, not sure if it will really have any effect to dissipate heat or not, but am hoping they will ensure longer life of the ULA and Z80.
More pictures tomorrow of the 128K :)

where are the pics of it in the bath?
and some pics of it all dirty.
i feel cheated :p
Yeah but no but ... it's the "before" and "after" that we're ... err ... after.
Give us the dirty pics too!!!!!!!!
She actually had a good upbringing, so it was only her "interface" (membrane) that was faulty. Sorry to disappoint, but it wasn't like she was stripped naked of her ULA or anything so intimate ;)
Yes, its the 5v power regulator that is directly connected to the heat sink.
Only this version had it.
I understand they are quite "rare".
In Spain they were released with the numeric keypad in the box, in the UK, they were released without the keypad.
The box is red.
I bought mine from new in 1990(?) but unfortunately I don't have the box anymore.
yep, linear regulators are really inefficient.
iirc the 128k draws up to 1.85 amps.
to get the 9v down to 5v the regulator needs to get rid of 4 volts, at 1.85 amps that's 7 and a half watts! :-o
A tiny fraction of what heat is being thrown away.
Just ditch the linear regulator and use a modern DC-DC converter.
The ones I have for sale are alas only the 1 amp model so no good for the 128k.
