[ARC5] Tube Conditioning

[Robert Eleazer]

I have a set of five NOS 6883B's in an original sleeve I bought on ebay. Total cost including shipping came to about $5.00 per tube.

I want to use two of the 6883B's in a TS-520 I am repairing and have modified for 12V parallel filaments.  I understand that it is a good idea to crank up the filaments and apply some B+ to condition those tubes for a bit before use.

Can anyone explain that process again?

Thanks,

Wayne
