Hi everyone .
I am working on an Urei 1178 , Ch -A shows higher levels on meters but is lower on the actual output.
Also feeding both inputs a square wave this is what I measure on the output transformer.
EDIT: Input seems fine , I measure a proper Square at point 1 on the output transformer but skewed at point 6.
Upper trace is channel -B , lower is channel A.
Meters set at GR and everything seems fine , compression starts with input/output at 12' o clock on both channels.
All opamps are fresh except for the NPD5566 , all transistors have been checked and seem fine.
Any help would be greatly appreciated ( I mostly work on synth repair )
Thanks
