When you see something like 535V in a kit with a lot less voltage than that present, that tends to indicate a bad solder joint on a ground wire in the amp.anthonynchandler said:Paul,
5/6 on the A channel is 0.632V, but on the B channel I am getting that same 535V on the 5/6 [and it is 535V versus 0.535V]
On terminal 9 it is 3.746V. and on terminal 19 it is 2.964V
Terminals 9 and 19 show about 3V of AC signal, and this is the output of the preamp. Can you turn the volume up all the way on the preamp and run this signal through it again, then report the AC voltages available at 9, 19, and the left and right output jacks?
