Title: Aireon 1221a amp
Post by: Panama Red on May 07, 2021, 11:09:52 am

Hello everyone I just picked up this old jukebox amp and I can not find out any information on it other that it's for late 40's to mid 50's seems complete lots of surface rust and one of the 6L6 tubes has lost vacuum, I'd like to get it up and running maybe convert it to a stereo amp for home use anyone out there have info or advice?

First step is to find or draw a schematic.

Oh yeah, you'll need two of these amps for stereo.

ya I saw this but there were no schematics and I've looked everywhere for them some of the caps are in really bad shape so I can't get numbers off them and I'm nowhere near close to being experienced enough to even know what I'm looking at!

It's not unique technology. Look at other two-6L6 amps and steal the values.

Or stop buying and selling these things until you get more familiar with them.

I'm not buying any of them most I'm saving from an old abandoned property I have permission to salvage from, I'm trying to just find out what's worth saving! And I dont need to know anything to ask questions that's how you learn! So pipe down!

We try to be respectful to each other here.

And PRR is 1 of the most knowledgeable, well respect and liked member we have here, without question.   

That last 'pipe down' was not necessary.  :think1:

We do not act like that here.
Drop the attitude

I have done a bunch of old juke box amps way back in the day
You will not be able to do this at your current skill level

There are way too many things you need to know first
This is not a task for a beginner.
