Default Bogen V20 PA Amp Schematic or ?


I am having trouble finding a schematic for my old Bogen PA Amp Model V20. It used to have a junk turntable on it.

After 15 years of storage, I have decided to finish this into a guitar amp. It used to play pretty well through thru one of the 2 mic inputs.

Now I just want to understand it better, learn some new skills and fix it.

Then I can start playing some of that old time rock n' roll again.

Any help, schematic, shared interest?

I checked the Sams Photofact index - no Bogen "V20" listed.

Hi and welcome to diyAudio. I've googled for the the Bogen VP20 Turntable and all I can come with is replacement idler tires. Also searched the Bogen site itself:
and I came up empty.

So it looks like it's just a small amplifier in a Bogen "Record Player", not a PA amplifier. What's the tube compliment? I have a few schemantics for Bogen PA amps, maybe I have one close or similar to the one used in your turntable. Are you wanting to turn this into a practice amp, as I don't see an amp made for a record player could 'put out' much power.

The closest one I've found is the VP18 but it will set you back 14USD:

Sorry I couldn't be much more help!

I found the Sams folder for VP17 - push-pull 6V6 amp. Maybe close?
