I finally finished my Beepre build ordered back in Oct (somehow there was never quite time at home with an 11month old
).
Similar to this thread, I found A1/B4 resistances climbing into the 500Ohm-1kOhm range instead of dropping to 4Ohm:

I pushed ahead to voltage measurements. All are in spec except for C3/D3 on the nine-pin sockets. I measure 9.2V on C3 and 4.5V on D3. The high value moves with the 6BQ5 if I swap them.
It sounds beautiful, but does 9.2V at C3 on one of the 6BQ5's indicate a problem I should replace the tube for?
Thanks in advance! Kaleb
