Subject: CS60 PSU issue

From: Andrew Kirkby <kirkbyte@...>
Date: 2011-07-14

Hello all,

I am restoring a PSU in a CS60 and after recapping i have no +15v but
the +8.5 is fine.

I'm thinking it could be the power transistor attached to the 15v rail
however the reading of ~1.5v at the business end suggests otherwise.

Before i go swapping out parts, can anyone suggest a fix? I've checked
all the capacitors for polarity and continuity to the relevant traces.

Andrew
