Title: reference schematic needed, parallel SE 5881 build
Post by: centervolume on February 27, 2016, 12:01:29 am

Greetings all-

I'm trying to finish up a switchable single 5881 to parallel single ended 2x5881 cathode bias little number). Essentially the schematic I designed was tweed twin/bassman front end (treb., mid, bass tone controls) and a gibson GA-8 style power section/back end all in a hybrid tweed vibrolux/harvard sized package.

She is suffering from some issues mostly in the power section and I was wondering if there was a good reference schematic for an single ended parallel 5881 or 6L6 I could refer to trying to control high gain squeal and make sure I have enough AC filtering.

Similar designs I have heard referenced are the southbay captain crunch and brian schmittling's SSEL 30watt.

thanks in advance
