Hey id be willing to buy that amp !I have a unmodded head and cab epi valve jr .brand new ,hardly used i might do a part money part amp trade!!

Amazing score! BTW, that's a 4x10, not a 4x12, I'm pretty sure.

I was going to say the same thing. I'm pretty sure it's kinda like Traynor's take on a Fender Super.

Gee, fifty bucks is even beyond Krashpadian proportions. SCORE!

I finally decided on a pair of 10" Weber Signature 10s, after doing a lot of searching the web and then emailing Ted Weber. It's funny how mucked up the speaker wiring was in this amp, poorly spliced, butt connectors, etc. Yesterday I pulled up a diagram and wired it up, with the 2 new speakers, in series/parallel.
This thing sounds sweet! I will post some clips if I can get a good recording of it.
I've got the reverb tank on order and am looking forward to playing with some real spring reverb!

I followed the wiring diagram for series/parallel, but just for peace of mind, is there a way I can verify that the amp is running on 8ohms?

If I understand what you're asking correctly, use a DMM to measure the resistance of the four speakers at the connector that plugs into the amp. You should get around 6-7 ohms if they are wired for series/parallel for 8 ohm impedance.

Oh, ok, thanks. Actually, there is no connector that plugs into the amp -- the speaker leads from the amp are hard-wired into the circuit. I guess I can just desolder those leads and put my meter probes at those two spots?

Yes, you want to desolder the connections, then measure.

It measured 7.4 ohms
