SpeedRacer	Re: Cathode bias questions The older Fenders are running lower B+, roughly 360-390V and 250 works great in there IMHO. THey also used output trannies with a higher primary imp, generally 6.6k for the cathode biased amps with 6L6's. The B+ in SF Bandmasters tends to be in the low 400's in my exp, so you could probably pop a zener in there to lose the excess voltage, get yourself into the mid-high 300's and it would set up just fine. To be perfect you might try to find a 6.6k output tranny. Hammond probably makes one that will work nicely. The old CB sound is one of my favorites. YOu should be down to around 18-20W output, which is still plenty loud for leads.. and a nice break up. Try reducing the amount of -fb as well..
