TRS-80 repair, those damn filter caps
Posted: Mon Apr 18, 2011 2:59 pm
I picked up a free TRS-80 Model III, all it needed was a filter cap replaced.
So I replaced the filter caps on the board that was broken, and didn't bother with the other one as I'd have to remove the drives.
30 seconds after successful power up *KABOOM*, there goes the filter caps in the other PSU.
Never seen one of these explode before, just crackle and smoke.
Cool thing is, it uses the same caps as the BBC range of computers, and I have a bunch lying around.
