Thanks for your post, Craig (#4161).
I checked the 20V and 21V rails that are generated on PCB2. They measured 10V and 11.5V respectively, so there is a problem here too.
Can you by any chance remember which components had failed on your unit? Was it the regulator transistor (2TR8) on the cct diagram?
Thanks,
