i find myself in need of a schematic for a 550B
the only schematic i have found so far is a hand drawn
doc that only has the audio path. (and a bit harder to follow than
a regular schemat)
With A-2 in the -16 volt rail falls to about -1.3v
take out the op amp and volts are good.
same thing with a new op amp too.
also still looking for a schemo for the (evil) 550A-1
thanks
