Hello everyone,
I'm further along in my building of my first grid driven amp and could
use some input.
I USED to have a Care and Feeding of Power Grid Tubes, but I lent this
'bible' to someone 5 years ago and haven't seen it since.
Could someone give me some idea of what voltages I should be looking at
and maybe the currents as well.
I have the parts to build a solid 4100 volt supply which is CCS at 750
mils. Have tested it and all seems well.
Running 600 mils with a pair of 4-400's is well within plate current
specs and will give me about 2400 input ( not considering any E drop due
to load).
Any suggestions what to run for screen Voltage? I can do 400-500 volts
easy with parts I have.
How about grid bias? Any ideas what I should be building for? It will
be variable, but what should the max be? -150? ...-100? ...-175? I
don't have a clue.
Maybe some of you who have gone before me, can shed some light on what
values worked for you.
Thanks in advance.
