been pouring over tall the thread info .
and couldnt find a few things.
im rebuilding my v72(not 'a') , unfortunatly it had a lot of the shorting problems
that occure in the older ones.
what are the transformer ratios. ?
im looking at using sowters , i know they have the choke.
the rectifier (i think) could be replaced with a more modern one ,
does any one know what type ?
is it a 'full wave' . (what type ?)
im also using ef804s they appear to be a bit costly ,
are there any alternatives to these tubes.
im also intrested in a volume control ,
from what ive gathered R18(80k)
is the resistor that sets the volume,
any concepts on this ,
as ive read through the pages , ive seen 'stepped attentuators'
as the solution here.
i would be greatful for any help.
