Tomorrow I will begin resurrecting the above unit, which has lain unused
since 1965! I am the original owner, but cannot locate the manual, and
forget the various operating modes & tuneup procedure.
Would anyone have a manual scan they could send along? Even a schematic
would help.
I plan to cleanup the unit thoroughly, then remove the final amp
(4cx150), then slowly apply ac to see if the original hv p/s caps have
survived. If so, I will replace the tube and attempt to tune it up.
What is the recommended drive level and plate current at max linear
output? What bias? What are folks using for a RX/TX transfer relay? I
recall I might have used a standard Dow-Key years ago, but that is
nowhere to be found.
Any advice appreciated!
