FS: Stromberg Carlson AU-57 tube amp

whitelabrat · 20th May 2009, 03:55 PM

Stromberg Carlson AU-57 lightly modified for guitar work. Insane gain (and distortion) from two input stages wired in serial. This thing rocks!

I've replaced the electrolytic caps where appropriate and have added a quarter inch plug for input and for 8 ohm output. Also replaced some film caps with orange drops.

6L6GC tubes, 5U4GB, 6X4, 12AU7, 12AX7 tubes included:

$100 + shipping.

Hi, is this unit plug and play for guitar? thanks, Doug

It sure is! Plug in and go for it. If you have too much gain you can replace the 12AX7's with 12AU7's. I think the best sound is had while pushing the output tubes to clipping. I can rewire the output for 16 ohm if needed.

Built like a tank, and looks like one too.

newbie, so the system won't let me. Can you email me? Thanks! Would love to hear a little more about the sound and setup, but I'm pretty sure this is what I'm looking for.

Hey I was wondering if you remembered how you wired your inputs in serial or even better if you had a picture of your mods. I just picked one of these up and what you have done sounds pretty cool. Thanks The sloth
