Default Repair Help on Orion 2500d

Hello, I'm working on an Orion 2500d that I need a nudge in the right direction on.

So the power light doesnt come on when i hook it up.

It idles around 5 amps and makes the little click noise when its powered up.

All the power and output transistors seem to be fine.

No burn marks on the board or anything else that looks out of the ordinary.

I did however notice that the 2 matching vertical driver boards heat up significantly while idling.

Any tips on this type of repair?

Do you have the master/slave switch set to master?

Have you tried running all controls/switches through their entire range?

Do you have both positive and negative rail voltage on the third leg of the output transistors?

Since the driver boards are heating up (some heating is normal), you probably have rail voltage but you need to check if none of the previous suggestions have helped.

Do you have both positive and negative regulated voltage on the op-amps?

Yes

Yes

No, I'm not getting any voltage from the output transisters 3rd leg

I actually am only getting .1 volts on the rails on the audio side.

Do you have both positive and negative regulated voltage on the op-amps?
Yes I have + and - 12 volts on the op-amps

Are the power supply FETs in the circuit?
