It seems like most of my posts are me asking for advice, hopefully I can start to contribute a bit more in the other direction soon.
Anyway My AMP1-B has been built for a while and the soldering looks good, a small bit of practice and the right tools go a long way. I just got the PSU going over the weekend and have 24, -24 and 5v. Iím not sure if this is important but the 5v and +- 24v are from two separate PSUs. I am not sharing the ground directly between them.
When I power up the Amp it does not work. Voltage polarities are fine, the voltage from the PSUs doesnít change once the Amp is up either muted or awake. The Amp is completely dead though. When awake there is no led and no relay click. I am reading voltages around the board and to the chip but I donít know what I should be looking at to help zone in on the problem. When powered up for a little while the chip gets slightly warm to the touch.
All thoughts and suggestion appreciated,
