Hoffman Princeton Reverb AA1164
« on: April 27, 2015, 02:33:16 pm »
I'm starting to work on building a Fender Princeton reverb amp.. On your site you mention to set the bias for the 6L6's to about 30 mA. When adjusting the bias 10K trim pot, what should the Intensity control be set at? I imagine this affects the bias setting. Thank you.

Set it to zero. Better yet, turn the trem oscillator off.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

Hoffman Princeton reverb build info is here
http://el34world.com/schematics.htm#Hoffman_Princeton_Reverb_


As Brad mentioned, it uses 6V6's, not 6L6's
A good generic setting for 6V6's is around 25ma each



Turn the trem off when setting the bias
