Ok this is my new amp project will probably make a 5D8 twin out of it or something simular. It is a AO15C amp out of a Hammond Tone cabinet and it has 4 6v6's though I will probably only use two sockets for 6l6's. What is cool there are plenty of sockets to go around will have to change three of the octals to novals but that is no big deal. And then strip out the cans and the guts and the chokes that are on the chassis. It has TWO Output trannies one for the bass channel and one for the treble channel. The treble channel was one speaker and the bass 4 12 inch speakers from what I have found out so far. I am hopeing and guessing the 4 bass speakers were 16 ohm which in parallel which they said it was would be 4 ohms. No idea what the treble speaker was I will have to do some more searching. I would have never found this but I put a wanted ad on craigs list to get it. The price was not bad so I grabbed it. Now 3 of the tubes 6v6's are marked Realistic Lifetime made in Holland any one familular with these? Are these Old Radio shack tubes or are they something different?
