setting tube bias

D. P. (noetical1) - 12 Mar 2003 15:59:12

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)

See this post in context.
