Geloso PA Amp Conversion

[madstokedsurfers]

Hi everybody, I'm new to this forum. I have an old "Geloso" PA amp (Italian made, probably similar to Bogen or others) that I'd like to convert to vintage Marshall-type specs... it should be pretty easy, as the amp runs 2 12Ax7's in the pre, a 12at7 in the PI and 2 El34's for output. Has anybody had experience with these amps? I'll gladly supply photos if needed.
Thanks,
Dave

Hi there!
Those Geloso amps were built like tanks!!! Brings back some teenager memories from 1968-69-70...
I was still in school and "stuff" like amps were hard to get hold of. The school had one of those Geloso's and we commandeered it up for use with a local schoolband. We plugged a guit into that one, and she "sang" good enough for then. Of course we were none the wiser about anything technical those days in trying to outdo the bands of the day!

It would almost be a shame to gut a beaut like a Geloso...
But then it is your amp.
