Re: 7A13 shorted +15 rail

on the 15v lines they used 20v caps which is not enough. replace with
modern 35v aluminum caps. this should be a minimum effort. it would be wise
to replace all the old tants

So Jerry, are you saying just change the tants and eliminate any question
as to there condition.? I'm up against the same issue of Tantalums and
whether to just replace.Brent

It is best to replace all the tants.

Hello Everyone,
Does anyone have advice on troubleshooting procedure.I have a 7A13
plug-in
with +15V rail shorted. The mostlikely cause is tantalum cap. What is
best way to findthe errant component?

ThanksLarry
