Hey Everyone,

Here's yet another one of my amp projects that I've got scheduled for this year, after some debating in my head, I've decided to see if I can convert my old 80's Peavey TKO 80 non-EQ Bass guitar amp over to a pre-amp so that I can use it with my Behringer K3000FX Keyboard/P.A. amp.

Here's what I think I'll need to do in order to complete the conversion:

1, Remove the PCB from the amp chassis.

2, Remove, or de-activate all the power amp circuitry on the PCB, leaving just the preamp circuitry fully working.

3, Design a new +/- Regulated 15V DC supply to power the preamp circuity.

4, Install the PCB and new power supply in a 2U 19 inch rackmount case, re-using the original black plastic front panel.

5, Test it out with my Behringer K3000FX Keyboard/P.A. amp.


Doing that will effectively give me a 300 Watt solid-state Bass guitar amp.
