Title: wanted cf driven power tube schematics
Post by: jbrew73 on January 19, 2009, 08:56:14 pm

im looking for schematics of  amps where the power tubes are driven by a c.f. that has the neg bias voltage applied to the cathodes of the driver tubes. i think the hiwatt 400 and ampeg svt are like this but im looking for others that any of you may know about. just looking for ideas for a bass amp build.
