Yes I have the +and- 36volts into the driver boards but the problem is that I'm getting +36 volts out on the right driver board to the speaker when there should be little or no voltage. Again,I'm wondering if a bad 2SA56 xtor would be the cause? Mark

Alan,
Replaced both sets of xtors to no avail.I'm finding that there is 36 volts on the output to the right speaker and not on the left.Perhaps there is a bad 2SA56 xtor letting 36v through?

Hi Allan, Thanks for the reply,no,it does not blow them right away.It begins by "frying"a resistor adjacent to the fuse.I unhooked the wiring harness from the transistors and the problem disappears,so I'm going to replace both sets of xtors and see if that cures the problem.Everything appe...

The fuses on both driver brds are blowing ,would replacing both sets of xtors in the amplifier solve this problem?

Thanks In Advance
Mark
