What's that big tube in the center, rectifier or voltage amplifier? If
it is the rectifier where are the input stages/voltage amplifier tubes?
John - thank you for your reply. As noted below by Keith, it's a 5Z3. With
separate AC and B+ switches, the amp is also set up to run an 83. The 5687
input/driver tubes are behind the output transformers and can't be seen in
that photo, but can be seen here (older photo without the globe 46s):

The bass response probably sounds "better" because the damping factor
with the 46 is lower than with the 45.
I thought lower damping factor would result in "worse" bass? Are you saying
that I'm prefering the "loose" bass produced by a lower damping factor?
