of course I saved it, now if I could only find it :whistle:

The arrangement was typical, as you say, but it looked like both the triodes of the 6GW8s were post PI and in series with their pentodes. I believe a 12**7 (might have been an AU or AT) PI was feeding it. I have never seen triodes in push pull before as I am still green with tubes. Perhaps this explaination makes more sense. As soon as I find the circuit Ill post it.
