Looking for a little help with this Taramp 10.9k.
The amp came in with bad power supply connections along the 12 volt buss bar that feeds 12 volts to all transformers. I removed the buss bar and cleaned all the connections and installed.
The amp comes on, it has oscillation and produces audio, but only at low volume. If I try to drive it into a 2 ohm load, as I increase the volume, it will shut down, when its drawing about 15 amps.
It appears to have a regulated power supply, the pulse width is extremely small, and as I drive it, it gets slightly larger, but shuts down.
I do have the schematic for this, but I am unsure of how it measures overcurrent in the output section,

Do you see pin 6 of the 6N139 opto-coupler being pulled down?
Does it have a code via the LEDs to tell you what the fault is?

Hi Perry,
Sorry for the late reply, haven't had much time for amps the last few weeks.
When I drive it into shut down, the voltage goes from 0v on pin 6, to 4.6volts.
And the Red lite flashes 2 times, until I remove the remote.
The original problem was that the power supply (12v), buss bar had bad connections that feed at the 6 individual power supplies.
It eventually burned the top copper trace that was also feeding 12 volts. I repaired that, and now this is occurring.

It looks the the voltage for turning on that optocoupler, is derived from the current sensing resistors from B+ and B2.
I think I sent you the schematic for that amp, do you need it?

Do you happen to have a schematic for the HD 15000?
I wonder if it uses the same outputs as the schematic you shared?

I emailed the company with no response. I might try calling them.
Just need to know what outputs the 15k HD uses. They part number is ground off.
