Amp powers up and produces rail and regulated voltages ..
Relay enguages but i get no output at all ..
Not sure of the model number since the pop top is mising and no other markings anywhere on the amp I called orion with the serial number but that was no help..
Anyway anyone have any ideas on where to start since i get no output ?

R-R oscillation?
For any heatsink mounted transistors with a 10 ohm resistor in series with leg 3. confirm that the 10 ohm resistor is within tolerance.
This amp may have a strange problem with clipping behavior. It may not be something that can be resolved.

I'm gonna have to pick up a new probe and see if that is the issue with my scope ..
I can't get it to lock into anything I even tried just probing the battery + wire and can't even get the trace to deflect

Run a short piece of wire from the test point on the scope to the center conductor of the channel you're using. Will it trigger on the test signal?
Yes I can get it to trigger with a wire ..
The probe is bad going guess I'm going to buy a new probe

Anyone know if there are common problems with this amp ?
I do not get rail to rail oscillation on the outputs wondering if anyone can point me in the right direction in where to start checking

Back to this amp ..
Anyone have any ideas I spent a couple hours already and can't figure out why I'm not getting rail to rail oscillation on the outputs

Anyone have any ideas on this amp before I give up on it ..
All 10 ohm resistors that connect to the outputs are within tolorance ..
I also have been checking resistors diodes and transistors and everything is testing fine ..
Still do not get rail to rail oscillation ..
