[Boatanchors] looking for 30L1 T/R relay

While going through a 30L1 I that won't 'key' I discovered there was no
voltage at the T/R connector.  The bias supply, which powers the relay, is
fine so I suspected an open K1 relay coil or resistor.  Much to my dismay,
upon removal of the back panel, I found there was no T/R relay.  If you
have one or have a parts unit with one, please contact me.  Alternatively,
perhaps you can point me to a source for a new one.  The Collins part
number is 970-2140-00.  It's a DPDT good for 2 Amps and has a 10K Ohm coil
(for DC).

Thanks for your time.
