Garey et al,
 
I appreciate your comments. Perhaps I did a little too much work
on my T-4XC. 
 
I just finished restoring my transmitter, and during my work I
found a few problems with wafer misalignment and too much "play"
on certain wafers. Can you comment on the best ways to correct these
problems?
 
I would also like to know what typical settings for plate and
load controls should be when loading into a dummy load. I have never owned
a working C-line before, so I am not sure what "normal" is.
Suffice it to say, I believe my plate control is turned relatively
high. I just about "run out of room" on 10 meters.
 
Also, what kind of output power should I be getting. When I
follow the tuning procedure given in an errata sheet indicating that I
should limit my plate current to 340 mA in order to meet FCC regs, I only
get about 85 watts out on 80 and 40 meters. When loading to full power,
what is the maximum plate current I can load to without melting my new
finals?
 
For those of us that were discussing how to obtain knobs for the
Drake: I called Caltronix today and they confirmed that the 50-133 knob is
only available from the manufacturer if they buy 500 pieces. They are
looking for another vendor who will sell in more reasonable quantities. In
the meantime, they have available the 50-123 knob, which is 1.04" in
diameter vs. the 50-133, which is 0.93" diameter. Has anybody had any
luck with other vendors? I still need to replace one knob.
 
I hope to chat with you guys this Sunday during the CE
Contest.
 
73,
