Here is a Peavey 5150 :)

 

 

 

:) notice the bogus little rubber bumper that is tacked on as a support for the flimsy little preamp PCB :)

 

..... it's not even centered right on the board. :)

 

:) a wino in some back alley could probably design a better preamp board and support than that. :)

 

Maybe the Peavey Engineers ran out of ideas and consulted with one :confused:

First of all, looks like you've got some problems there with your power section... :eek:

 

 

Second of all, that preamp board support is screwed in with a METAL SCREW. There is a metal screw holding in that rubber washer, and I had some arcing between the screw and the preamp board, and it actually got worse and worse until the amp stopped working entirely.

 

It started melting some traces but at least it still works fine and the problem got fixed before anything was damaged to the point of needing repairs.

In terms of wiring, which one is better? I know they sound the same but the newer ones have an external bias.

 

Looks like the pots are on a board on the new one and chasis mounted on the old? Anythng else?

Don't really know which one is better. The power tubes are chassis mounted on the old version.
