I am restoring a Stromberg AU-42 - 6L6G question


I am restoring a Stromberg AU-42 and I want to keep the original can cap look. I cannot find a 50/40/30 in order to keep the 50uf cap at the cathode side of the 6L6 outputs. The circuit is push/pull (2 6L6’s) and the cathodes are tied together to 50uf/50v parallel to 200 ohm resistor to ground. I believe this is the current source for the 6L6’s. I can find a 70/40/40 and a 80/40/30 can cap. I am wondering if I can increase this 50uf on the 6L6 cathode to 80uf or 70uf. My gut says this will be okay although in the back of my head, more capacitance means more current on demand which my gut says should still be okay. I don’t want to heat up the 6L6’s. Any advice would be helpful. I really do not want to use individual caps but if I have to I will.

Thank, Tom

Well, I completed the restore and it looks and sounds great. All of the coupling caps I replaced were really leaking and way out of spec, one was leaking 2amps at 400v and not going down, most increased current leakage during testing which should not be the case.  A couple of the bypass caps would not even register as caps with my Sencore and my cheap tester.  I also replaced a few resistors that were out of spec.   I did use cans, sorry, I like to keep original as I can and they fit really nice and tested excellent.   I mostly used orange drops for everything else.   Yes, I even took out the time to unsolder pins to add the new components, I was going to do the old wrap around but I kinda knew I wouldn't before I started.

I am not changing the nonpolar plug and I am currently waiting on the safety caps.  If the .1 line caps that are installed in there now are anything like the other caps I have replaced, then they are coming out either way.

Cool looking amp.

Are those chicken head knobs bakelite?
Big fan of the 6l6G sound. To my ears a great compromise of the El34 mid and KT88 bass.
