[SignalOne] Who works on CX7s?

[Charles Hugg]

I have acquired a Signal/One. It is a  really nice CX7 that has been
converted to a CX7B, I think. The Front Panel label says CX7 and the SN is
#256. But it has the Signal/One CX7B Power Supply board installed and it has
the Signal/One LED Readout installed. Both of these units have Signal/One
CX7B 1974 labels. It also has the Tube Screen Fuse installed on the back and
a meter light installed above the S meter. I didn't get much paper work with
this one. There is an  Info Sheet in the manual outlining the mods on CX7s
to make it them CX7As and there is a similar sheet from Signal/One covering
the mods to convert CX7s and CX7As  to CX7Bs, but I don't know if all of
this work has been done on this radio.
It seems to work. I plugged it in and turned it on. No smoke. I heard some
strong signals on 20 meters(good S-Meter readings), but there was what
sounded like an AC hum on the audio. It was a pretty loud hum, so I turned
the radio off. I think that it has set up for quite awhile. It probably
needs some caps replaced.  This transceiver is one of the cleanest radios
that I have seen. I looks almost new, especially on the inside.
The boards are shinny and have not been abused at all.. There is not really
much dust collected on the chassis.
I think that it might really be a keeper. It even has the amber and green in
the readout like the CX11A.
Does anyone know of someone who will work on these radios? I could take it
too
them within Texas or surrounding States.
