Matt, are your speaker amps ultra linear? And I noticed that you offer a 6W6 option for your Genesis 6 amp, does it still put out 6 watts with this tube?
Howdy, they are not Ultra-Linear, typically the 40% tap is a delete option from my OT winder. The Genesis6 is running about (trade secrets, 250v on the plate @ 40mA, CCS Bias) = Awesome!
