So I'm here repairing an old IBM 5151 monitor, and I've ordered replacements for all the electrolytic capacitors.
I've found like for like replacements for each one except weird one which, according to the circuit diagram sits at a centre tap of the flyback and the collector of the horizontal output transistor?
It's C505.
Non polarized, 18uF, 25v. Apparently.
So the replacement caps arrive, I've had to obtain a 22uF 25v NP cap as there weren't any 18uF 25v available, not sure what the consequences of this might be.
But check out the attached.
The replacement caps are tiny, I ordered two different 22uF 25v NP caps and one is pictured beside the original 18uF 25v NP cap.
Something's afoot. That size difference is alarming.
I feel I've missed or misinterpreted something.
Would really appreciate some input here...
