Turned it on this morning, all the lights lit up and no volume. Checked all the cords, VP and everything is ok. Anybody have any suggestions as I tare into it today looking for an "obvious" problem?
Wonder if Peavey is still repairing these amps.
Where is Mike Brown when needed?  |

Make sure a wire has not come off the speaker. Wiggle the speaker connection... wiggle everything! Do you get a noise at all, or is it completely dead?

| Roy, I hope you know Mike Brown is no longer with Peavey. Sad. If it has an effects loop, try using a cable to jump from the in to out. Peavey is known for a contact problem there. |

Effects loop (typically on rear) not front inputs.

All effects loops checked. Time to pull the chassis and see if anything is obvious.
Hope Peavey still supports the Session 2000. Will give them a call.
Thanks everyone. |

The amp doesn't get moved. It stays in my music room under a cmptr desk. Like I said earlier it worked one day and not the next. I will bring in my 112 and hook the 2000 up to its speaker. Nothing obvious looking at the chassis. It will go to a tech over in Boise who is on the peavey list next Tuesday.
Thanks to all for the possibilities of whatcould be wrong. I had already cleaned the jacks and jumpered the effects jacks. |

| Had a similar problem some decades back with my LTD 400 and, as Stephen suggested, one of the speaker leads had somehow worked itself loose. Good luck! |

| I fixed two of these on the past. Both same issue. There a multi pin header connector near the middle of the power amp board that should be checked A ribbon cable plugs into it. Check for cold or broken solder joints on the underside of the circuit board for that connector |

| Got the amp repaired. Problems with dead HV SW supply and class D amp. Missing drive signals from the controller board caused by shorted de-coupling capacitor on the -/+ regulated rails. The "authorized" Peavey tech couldn't get the correct schematics from Peavey. Fortunate that I had a set thanks to Mike Brown back around 2001. |
