Mine has an EL34/6L6 bias switch but I just ordered 6v6s from thetubestore.com and they gave me the right grade of tubes that I can run in the 6L6 mode.
It was just a curiosity to know more about the inner-workings of the amp. I haven't used yellowjackets but I am using 6v6 valves in it right now and it sounds pretty sweet.
I was wondering how many gain stages the raw mode on the rectifier series was since that mode is a lot less gain than the vintage or modern mode. Just a curiosity of mine.
