Hello all,
Has anyone on the list built or used the 833 tube in
a grounded grid amp? I cant find any information on
the data sheets or circuits in old issies of CQ, QST and
73. I need some advise from someone who has experience using this type of
triode in GG service. I have
plenty of tubes and a 30 amp filiament transformer. My idea was to use two
tubes in grounded grid to simplify the construction. But, I am worried that
the tube will not be happy without the -70 volts bias specified in the data
sheets? I dont want to destroy the tubes on first power
up. Will GG operation be possible with the 833?
Thanks, Eric
