Your 2-B is Version 2, (change at s/n 6290,) and has one more resistor
and one more capacitor than Darrell's! Both changes are in the BIAS /
AVC

Yes, the 6EA8 is a direct replacement.
As most know, a tube tester is at best a rough check of a tube's
operation, especially in RF use.

Hi George,
you don't have to apologize, it's an unhandy feature that's different
than most lists and hard to remember.

Garey,
My 2-B does indeed have the earlier circuit and does not have the double pole
switch.
I am wondering how difficult it will be to find a

Has anyone done the BB Technical Services Hum modification on their 2-B?
The mod replaces R56 with a jumper and adds extra capacitance to C70. This

I've not tried it, but there is a reason for R56 being there. The

Thanks Garey! You are a wealth of information.
The schematic that came with my 2-B manual is yet a different version from the
two schematics on your

Wow! A new version. That would be the correct schematic for your

Garey has confirmed that the schematic that came with my 2-B manual is the

The mod has replaced the 6X4 rectifier tube with solid state diodes.
The tube is serving no purpose and can be left out. Most likely the
