Those generally look OK. I'd be more confident if you removed the rectifiers and installed the outputs. I'm assuming that the outputs are out of the circuit. Is that correct?
Yes, they are out of curcuit. Ok Ill remove them. Remove the jumper when I install the outputs correct.

Remove the rectifiers but the regulator will have to be in the circuit. It's on the same MEHSA strip as the rectifiers.
Reinstall the outputs.
Leave the jumper.

Leave the jumper.
why is your scope saying it's 580v?
Confirm that the rail caps are discharged.
Are you using a 1x probe when the scope is set for a 10x probe?

ok i will check that they are? I think it was set to 100x. The probe is what came with the scope and does not have the switch on the probe itself. i ialways just look for the signals until i become more familiar with what i am looking at. Let me adjust the scope and check the caps.
Those look OK. For the waveforms I got, look in the Rockford folder. They are near the bottom of the repairnotesrockford.htm page.
i installed the rectifiers back into the amplifier. Should i leave the jumper wire before i power up the amplifier for the first time?
It's drawing a little too much current 2amps at idle perry, so I haven't verified audio yet either. I did use the thermo and one of these transistors is over 100°f Q2000.
I don't have current draw but I just replaced the terminal block (no changes to OEM amp) on a T1500 and the idle current is 1.3 amps during the mute delay and 3.2 amps after the output stage is enabled.
All 4 of those drivers run hot.
