Hi Gordon,
Yep, I can remember installing new T300's at the NZPO and now de-commissioning
them a few decades later.
They are pretty straightforward and still have a good following and many are
still in active service.
What do you wish to accomplish? If you want to utilise them as a basic 2 meter
repeater, no problems as you can set up the radios as a basic talk through
repeater.
What versions do you have, the /02 probably were the most common and the /01
were made for exclusive NZPO use (BNC test ports on the front for LO alignment).
I'm guessing that if they came out of emergency service use, they more than
likely were on the old CD band of around 149 MHz @ 25 KHz, so would need
minimal re-alignment for amateur use.
I've got The manuals somewhere on PDF if you require them.

Sounds like you have a pair of T355 T356 radios,
You may well want to open up the TX PA unit (Behind the alloy shield) and
change the electrolytics in there as well as this area
is a well known area of trouble and can cause no end of spuries.
Just ensure that you replace the caps with 105 deg C varients and you
should be fine and give you another 20 years of service :-)
Thanks Gareth,
Tait equipment is fairly new to me - even
though I passed their
Christchurch factory every day (some 40 years ago) on the way to work. Most
of my
'fixit' time was spent on Collins, Wilcox, and yes, Collier & Beale
transmitters, plus
Cossor & Marconi radars.
What I have here is two pairs of T355 T356 VHFs. A pair of similar UHF
equipment,
along with an AWA 70 cm duplexer and a very interesting 150 MHz duplexer made
in Finland. Regrettably, someone has cannibalised the rack wiring with
sidecutters
so it is a rewire and make a new monitor panel.
Many thanks,
Gordon.
