[R-390] Vacuum tube question

[Kenneth Crips]

I have a Viking II transmitter which has the low modulation levels in part 
from low au.  I am not interested in extensive modifications to this unit I 
would just as soon leave it in stock condition.  There are a number of tubes 
which are a direct replacements for the pair of 6AU6 tubes at the beginning 
of the audio chain. Some of these replacements have either a higher 
plate,and/or higher grid dissipation.
