im working on this amp and replaced the op-amps in it . The outputs are getting both positive and negative voltage.

But the right channel is dead I checked the drivers and both have the same reading on left and right channels so do the op-amps

wondering what to check next

What do you mean by:

What readings?

Email me if you want the schematic diagram.

both op amps they are the 2068

Pin 1 0.4
pin2= 0.4

pin3= 0.4

pin4= -15.60

pin6= 0.4

pin7= 0.4

pin 8= 15.60

left channel is working right channel if u crank the source up u can hear music through the right but very low output

ok i looked at the diagram and tryed a new 4558 and tested some more in the output section but still same problem

[Perry Babin]

You'll have to trace the signal through the amp. Is there no hope to get your oscilloscope working?

[mike49504]

dont think so i tryed to calibrate it again and when u calibrate it it should show a nice square wave but its not

[Perry Babin]

It may be a bad probe. Try calibrating it by using a small piece of wire to connect the cal signal to the input port.
