Bogen H30 Chassis + PT +OT + Choke

[Super_Reverb]

So, I managed to get my paws on an H30 PA amp in good condition and am wondering if y'all have any ideas. Presently chassis is config'ed for 2 x6L6, 5U4, and four octal preamp tubes. I want to keep the outputs and rectifier, but plan to use 12ax7 for V1/V2 and either 12ax7 or 6SL7 for PI.

Am not sure of PT secondary voltage, but would like to implement an adjustable PS for PI and output stage.

Any thoughts?



Cheers,

rob

Only thing I would say is that from past experience I find the old Bogen amps to run higher voltages than expected. Maybe because of modern wall voltages these days.
