Dear all,
just puted two new 3-500ZG obtained from RFparts into my TL922 amplifier, what
suprised my a little bit is an idle Ip what is now 190mA/in CW mode... By
Service manual the idle Ip should be aprox 100mA for CW /2kV plate mode and
200mA for SSB /3kV plate mode.
Otherwise on PA0FRI PA mods page I saw 170mA for CW and 260mA for SSB suggested
for two 3-500 Z Eimac PA like L4B, SB220 and finaly TL922 By Eimac spec. sheet
for 3-500 advices 115mA per valve...
Now Im in doubt where the truth actualy lies? Are 3-500Z and 3-500ZG so
different?
Any idea or comments are welcomed!
Tomas, OK1DXD
