Thanks man.I hope its the bias cap.All of the filter caps are new.

I have a Fender Bassman AB165, ( modded to AA864 ),it sounded great for a while but its got some kind of oscillation going on.Sounds like a bias problem does and its like it has a tremolo effect but as you know bassmans dont have tremolo.All filter caps and diodes were replaced earlier,except for th...

thanks!

Im not too good at reading datasheet graphs,just wondering if anyone knew the specs on the diode in these tubes.I know they were designed for detectors or something in radio but I may have a good use for one in an amp if it would work for me. Im using the 6SQ7 for a cathodyne PI and Merlin's page ha...

Doesn't changing the field coil voltage also directly change volume? I would keep it that way. I believe this is what Fluxtone is. www.fluxtone-speakers.com John Yes the sensitivity is directly related to the volume the speaker puts out. That sounds like something worth experimenting with.I have th...

cool,arent you the one that talked to me about the eh150 a while back?I built that,really like it a lot!wasnt even thinking of that being so similar

Just got a cool power amp,all octal,that used a field coil speaker and a HUGE 6k wire wound resistor in the supply.This thing has RCA 6L6G power tubes and Id like to ditch the field coil but I know I have to keep the B+ down for the plate and screen specs.What are my options to make this work?

yeah the stamp on the glass kind of veered me away from thinking it was RCA.I love the "replace with GENUINE "Zenith" Tubes".kinda funny

RCA or GE?

coolest amp light show I have ever seen.I'll make a video clip and post

I have an ART Multiverb LT.Got it at a yardsale,Have a BBE Sonic Maximizer 442 I traded an old radio chassis for.Pretty cool stuff for the home recording desk.I have about $15 in the two.

blue glow on the low notes.They are TAD 6L6GC.though you cant really hear anything wrong and all specs are good,what does this mean exactly? i know some tubes have the glow but ive never seen any in an amp Ive ever owned do it this so intense to where you can actually see the tubes push pull process...

Thanks guys,Zener it is! will try it out

from 380 to 350.trying to avoid changing the PT
