Hey Mike and all, my experiments with lower and lower mu drivers has lead to a new circuit inevitability. The mu=9 27 (+PP2A3) is still just a little hot for most CDs, but has opened the door to listening to just the EXO-173 on the input, configured as a simple grid choke. The sound is really interesting; you hear all the breathing and the fingerboard sounds, etc. I think the mu=6.5 12B4A is next up. If I had the patience, I'd use the 26 or another DHT; that, for a very rainy day. Anyway, the "inevitability" is that I will add a simple linestage module to each chassis, which can be bypassed with a switch. I would expect to use the bypass most of the time, but who knows; there have been so many big surprises along the way, already. So, here is the question: in terms of magnetician logics, would it be better to cap couple the output of the linestage (a la Bottlehead Foreplay), or would such a grid choke also tolerate a B7 secondary (a la "parafeed" 6N1P) and 1" of wire as a source? Thanks! --keto

Thats exactly what I was wondering. Thanks. Nice lead material on the EXO173, Dowdy and BFFC, BTW. --keto
