Do you mean the "Bass 300"? Old amp with transistor preamp?

Contact customer service at Peavey and ask for it.

I have contacted Peavey with no response yet. I am talking about the 300 series power amp with transistor preamp for Bass.

Hi Jon, that is the KB300, he has the Bass 300. older amp 1971. The forum thread you linked is for the right amp though.

head says "BASS" on the front, and "300 SERIES" on the rear panel?


Best is to CALL Peavey, but proper email is customerservice@peavey.com

Hey Enzo,
Any problem using MJ15024's instead of the 2N3773 in this Bass amp?

Not at all, but don't mix them. I stocked the MJ15024 as a more or less universal replacement for most PV stuff.

Here is the cross reference from PV
