Hi Pete,
I'm sorta glad I didn't get one of those, tho' I almost did.
Thanks for the detailed writeup, particularly on the relay job, as
that's more directly applicable to future work by others.
One problem with your webpage, the only pic that comes up when clicked
upon is the last one, of the socket wiring detail. I suspect that's a
small typo in the links, and easily fixed.
It's documentation like yours that pave the way for others to step into
things that they might not have otherwise.
tnx, 73,
Al, W8UT

Recently I purchased an R4B and T4XB from an estate sale as did several
others who subscribe to this list. Both the R4B and more significantly
the T4XB required a lot of work before they were air worthy. My two
radios were from a lot of 9 that were customized and used extensively on
CW. Some of the modifications were at best bizarre. One significant
repair to the T4XB was to install a new TR Relay which is a plug in type
unit that were later specified and used on the later TR-4's and T4XC's.
This relay has a different coil voltage and is physically smaller than
the typical ice cube relays or original OEM relay.
I have created a webpage to document how I adapted this plug in style
relay to the T4XB. Others who may be faced with replacing their OEM
wired in relay may find this useful.
The webpage is located on my website here:

While we are at it I am looking for a standard 40M (18.1 MHz) crystal
for the T4XB.
