Yes I set out to go with 12b4's as I always end up with more gain than I need. But you all caught me at a week moment with the transformer. I was just finishing my trials with the $12 Allied. when you were ploting this one, so I bought one, then well I have some 87's in the bin. what the hell group build sounds like fun. The rectifer is a 6by5 and i have not listened to it yet. The wallwart I got at the thrift shop is dead...John
