I assume you are referring to T2302, there are no 28xx parts on the PA deck. I
suspect what you are seeing is one of the lead wires from T2302, which is part
of the RF filtering system for the collector voltage to the drivers. It looks
to be bifilar wound, so yes, a break in the common lead would
sell me I'm ready to buy one.

First step: unplug each circuit board, clean and DeOxit the pins and sockets,
and reseat boards. This clears up an awful lot of 7-line problems.

1. All lights light up on a ham frequency except the mic gain green light.

Need more information.
Are the lights on?
Frequency readout?
Is it tuned within an Amateur band?
Are all the buttons on the front panel "Out"?
Does the relay click when you PTT or close the CW key?

Hello group,
In early February, I mentioned that I have the x-lock installed on my TR7 and
generally find it a very good modification. I wanted to follow up on that
comment to include one minor annoyance.
As best I can tell this is an annoyance for any huff-puff circuit installed
using the RIT

Randy,
If the "sticky paint" is the problem, give Claudio's (I4YHH) solution a
try:

It does actually work!

Randy,
I hope someone will chime in on the paint, but Mike March, K4QU,makes the
plastic end caps FAR cheaper than I have seen them on Ebay. He has three
sizes, as I remember, to cover the TR7, accessories and the L7 amps. Email him
at mikek...@gmail.com . No connection other than a VERY sati
Greetings to all,
I just purchased a TR7 that needs some TLC. Need recommendations on paint for
the cabinet, source for plastic end caps (watching some on Ebay currently),
microphones (yes, I realize a lot of personal preference is involved here).

Hi Garey,
My first reaction is, "Wow!" I was hoping there was already a muting
circuit, as with the TR7-R7 pairing, but in that case I doubt anyone
would use the TR7 as the receiver. I'll get my Service Manual out
and go from there.
Thanks much!

I'm not aware of any external 'Standby' control for the TR-7 receiver.
A quick look at the schematic shows that the AF OUTPUT chip has it's own
+13.6 VDC source on Pin 30 of the 2nd IF/AF board. There is a 22 uF cap
on the line, so the cut off 'might' be a little slow, but it looks li
Hi guys,
This morning during my vintage AM net, my antenna changeover relay
decided to quit on me, so I switched on my TR7 to use as a
receiver. As there's no standby mode, before transmitting (100
watts) I turned the RF and AF gain all the way down and manually
switched the antenna to the T
Hi Tony,
I am considering to repaint all the sticky wrap around cases here (in Germany)
with the help of a local car spray boot operator. I will probably use a car
paint out from the catalogue in a grey metallic colour but likely with a
glossy final finish. This varnish will be cured by an elev
