Dear members of the formum.
I'm sorry to bother you with questions about the truepath amp, but I'm stuck. I have limited capacity to understand why this amp doesn't work, however, when first powered up there were no fireworks. So that is perhaps a good sign. I need some advise what to do ?
As I see it I have three options:
a) continue to search for the fault with help and advice from members.
b) Simply buy a new kit and assemble it and hope for the best.
c) Ask a formum member to assemble and test it for me, since I have all the infrastructure in place already, anyone interested is going to be payed for the job.
Anyway, here is the status, All the power voltage is OK, the mosfet's is not warm. It all started with trying to mute/unmute but nothing happend, the led was off all the time. So I plugged in the speakers and music signal and the sound was coming on and off for a few seconds with some hiss noise as well occational.
So I unplugged the speakers and signals and started some measurements, as I read about in the very excelent instruction.
VPP sense 5V
VNN sense 0,5V
VBOOT1&VBOOT2 to HO1COM&HO2COM 2,6V
Rail voltage is 53,4V plus and minus
I have the softstart, PSU1 and 5and10V kit from 41Hz.
So any ideas or comments would be highly appreciated.
