[UK-CONTEST] OT 4xc350 BIAS

[Neil Ackerley]

Alex,

What range of standing current do you have with the POT adjustment.

I believe you need 100mA standing current for a 4CX350 for SSB.

Please dont laugh but I have a very ancient NAG 144 Linear (NOT!) Amp.
Seems to work OK at the 200 watt plus level. So I assume valve is OK.

Only odd thing is the BIAS contriol Reading in  the Jinglish handbook says 
set to 40 ma for 4CX150 or 350 (Mine has 4CX350)
Full adjustment of POT only allows me to set for 50ma
Does it matter,

Have I a fault or is the info wrong.
Might be easier if  book was in English !
