Those rifa caps are evil the smell. Does your monitor have the extra flyback on it ?


Tom
Extra flyback! Oh I'm not sure, let me check and get back to you.

So today it's the turn of the analogue board, since it's only giving 4.3v on the 5v rail. I have a box of capacitors ready to be installed, but it does mean one thing, I need to remove the analogue board and that means discharging the CRT, something I've never done before.
I seem to remember there being an adjustment on the analoge board for the output voltage.
Intro retro computers since before they were retro...
ZX81->Spectrum->Memotech MTX->Sinclair QL->520STM->BBC Micro->TT030->PCs & Sun Workstations.
Added code to the MiNT kernel (still there the last time I checked) + put together MiNTOS.
Collection now with added Macs, Amigas, Suns and Acorns.

I expect there is, but the caps were pretty terrible, leaking badly so I'm getting them replaced first. The Rifa caps were split too but I didn't find those until I removed the analog board.

Just be careful. If there is an extra coil by the flyback it will be hot when your adjusting the voltage. It is fed off the transformer output directly.

OK, appreciate the warning. Fingers crossed when the caps are done, voltages will be back to normal and I won't need to adjust them.
