RCA RS-193 SE 6BQ5 with small transformers a 5Y3GT rectifier, 6EU7 driver. I bought one of those wall mount plastic plates with RCA jacks on it at home depot, replaced the little lytic under the chassis and paralled a 150 ohm 2 watt and a 470 uF 50V lytic on each of the 6BQ5 cathodes and variaced it. You litterally have to solder the speaker wires on.
It actually sounds pretty good if the music isn't too demanding. The Bosa Nova tunes by Yo Yo sounded very nice over the EVs but the Steely Dan was a bit of a struggle. Without the tone controls and by lowering the volume to where it could handle it I would have not been able to enjoy it.
Not a lot of distortion but I wouldn't call it crisp and clean by any means. It cost me $10 plus parts and I had to pull a 6EU7 from something else to use it.
The 6BQ5s run a bit orange and if the PS is running like it should be the things are pushed right to spec with 250 on the plate and 240 on the grid.
Fun to mess with but no real potential. Bumping up the caps on the cathodes did boost the bass and except for the fact that I have bought nice Dyna ST-70s for less than $5 more than once I would call it a bargain for $10 and a few parts.
