Title: Realistic MPA amplifier
Post by: saturated on October 09, 2025, 04:07:59 PM
Hi everybody

 :tu:

I got to thinking I need something to work on.

A friend has lots of stuff but not really any cool guitar amps

I remember seeing a Realistic MPA amp that looked cool I guess it is a mono PA amp

I just wondered if this would be a cool thing to try to get it working if so I can go get it

(Maybe there are some unobtanium components idk)

I would find out what the model is first and then see if you can find a schematic for that model, I know ElectroTanya has the REALISTIC MPA-40 schematic so there might be more out there.
There will always be a use for an amplifier on your workbench eventually, I have a tube preamp pedal of the Mesa Boogie Dual Rectifier that might sound great through a PA amp as long as you have a nice speaker cab to play through.

At worst there will be many great parts to salvage from it and most likely a fantastic chassis to build a proper guitar amp in, just make a new faceplate and it can look professional.

Yes sir thanks in fact I was gonna post

"I've been around here long enough to know that the absolute first order of business is to come up with a schematic "  :tu:

Seems I recall he had at least two different MPA models I'll have to take a look one had a silver face and one was black face.
