6CJ3 rectifier or 6D22S rectifier

[56oval]

I,m building a push/pull 300B amp with seperate power supply for input/driver stage 6sn7 and 300B output stage .
I was going to use 866 or 83 M/V cons out weight the pros.
Next the 5AS4 better than most 5U4,s .

Reading about the T.V. damper diodes eg.Lynn Olson and a few others .
So what are your thoughts
6CJ3 or
6D22S Svetlana

looked at the 3B28 xenon gas more RF than the M/V.
Cheers
Malcolm.

NOS 6CJ3s are bullet proof. I used them in my bread board amps for a few years without a single issue.

MV rectifiers are so cuuuute (not a single issue with 866A in one year or so ... but ... yes they need more care)

Hi,

Go with 6CJ3. They do not require anode cap.

I,ve tried 8 different tube suppliers around the world none have 10 of the same 6CJ3,s.
different brands have different voltage drops 25v@700ma
50v@680ma
25v@350ma
Ih value 1.8
2.5
1.2
So I might go with the Svetlana 6D22S a hard valve to get pinout and ratings on.

Neither do 6D22DS - it's a cathode cap (same difference, though!)


I've been using 6D22S for a couple of years. Nice long (30sec) soft start, up to 600v h-k, ~350mA current and at least 1000v PIV. Forward voltage drop is only 10-15v.
Evatco sells them in Australia.
