Tom and Alan, thank you for your very helpful comments. I do have fans in my
T4XC and also my TR7 and they work well. I mostly use the SP75 with the TR7
and it works fine. I really would love to buy a DX Engineering processor for
the T4XC but they are very very rare-maybe one day I will be
John,
When I had my C Line, I used the Magnum 6 speech processor and it worked
well. I'm not a big fan of speech processors so I didn't use it much, just
when I
needed the extra punch. It may be more affordable than the DX Engineering
processor.

Hello, does anyone have available a S-310-CCT cinch connector for a TR7? This
is the one normally wired on the PS7 cable for rig control, the 10 pin
connector.
I've tried the sources outlined on Ron Baker's website and none in stock at
either source. Also tried an internet search, and

I haven't had to do that to one, but I would start with 5 pF, then 10 pF
if necessary. Be sure they are at least 2 kV caps, which is going to be
the hard part. They also need to be NP0 or 0 TC.
The trimmer cap is 2.7 - 8.4 pF, or a delta-C of 5.7 pF. The T-4XC had
a 6 pF parallel

Before you expend too much effort in this, do you have ANY tubes that
will neutralize? The RCA and Sylvania tubes were very close to the
same and either should neutralize without difficulty or changes. I HAVE
used GE tubes without difficulty also, aside the from fact that they
I use GE's in my T-4XC and they neutralized easily without modification,
with the variable cap near half meshed (pretty good). Oddly, I had RCA's
that I could not neutralize. But by the 1970s it was hard to tell who
really made what tube. Look for a series of dots by the tube number
stamp. Tubes
