RE: Quick one: Does anyone have Hickok 539C test data for 307A (VT-225) tube?

My 539 book does not include tube information for 307A but perhaps
the information for using a 600A on this tube will help.

filament 5.0
Settings JR-3020-4
Bias 32
Eng. 0
Press button P4
Mut Cond 2500
Cap-P

Please let us know if this works?

Regards to all,
John
