127

I have picked up a 127 preamp power supply that is used to power a
couple of 1- or letter plugins for use as instrument amplifiers. It's
quite a boatanchor and seems to work OK but I want to replace the
selenium rectifiers in it with silicon for safety reasons.

There are 5 rectifiers in there. To save me a bit of measurement work,
does anybody have any info on function/ratings of the rectifiers or
whether Tek issued a bulletin on their replacement?
