Thanks for the info...



The output tubes are 41's in PP, but the OPT is center tapped 'off' center. There is no phase splitter. The bottom tube's grid is feed off a screen of the top tube. They only use 175v on the plates. Strange, but it sounds good. I had no idea there might be good used field-coil speakers. I think I'll try to find a permanent magnet one though. I'm not really trying to keep it too original. I do love the looks of it and the vintage sound.

Thanks for the speaker specs.

Tom
