Hi dp,
Well, it's not easy to to. I watched a tube tech do this and it's not
that easy.
You need oscilloscope for sure and you have to know how to alter the
values of the Voltage of the various components in your amp.
(I hope I use the right words, for my tech English is not that well)
If these voltages are not right you won't get the full of your amp also
it will be bad for your amp as well.
My advice, get it properly done by an expert and ask him if possible to
show it how it's done.
You don't want to ruin your "63 amp nor your new NOS tubes....
Just my two cents,
Jerry S. from Belgium.

Subject: [SurfGuitar101] setting tube bias
Hi group:
Many of you all seem to be quite knowledgeable about amp mods and
fixes. My question seems simple: I need to learn how to adjust and
set the tube bias for my 1963 Bassman 50...I have NOS GE 6L6's that
need to be installed...
will I need an oscilloscope or any other specialized tools?
does anyone know a cool link that describes the bias process?
should I just forget about the DIY and seek the assistance my
friendly amp tech?
as always, any wisdom shared would be appreciated,
dp
(ps: the Bassman 50 through 4X12" Celestion/Utah cab with outboard
Fender Reverb sounds awesome...sort of like Brian Setzer but
surfidelic)
