    Last summer a friend of mine’s folks moved from their home into a old folks apartment and they didn’t have room for an organ so i said i would take it. The friend plays guitar so i thought i’d make a amp out of it because he has never played a tube amp and it will stay in the family.

    I had gutted it earlier and ordered a 18 watt tmb kit from Mojotone and today i started placement, found that the chassis is too narrow for a traditional 18 watt build so i moved the input jack to the back and cut at least a 1/4 inch off both sides of the turret board using a table saw. the board will be over the tube sockets a little bit still but it should be serviceable.

    i set it up so the master volume is last because i plan on doing a post phase inverter master volume.

    I worked on some soldering yesterday and today. Got the board populated. I would say this is my second favorite part next to first fire up!
    Nice to have a cup of coffee nearby too.

    Moved some cows, ate some pie, soldered some heater wires. All in all a good turkey day.

    That's cool. I've had an AO-43 laying around for years. I think I decided it's one of those things I'm not going to do. But it's nice to see people are still getting some mileage out of it! I thought about how to try to rig it up without completely redoing the insides and as you seem to be proving, it's not quite possible.
