...is a new RF relay.

On Friday evening I rushed home from work to participate in the DUBUS 2m 
CW event with hopes of working some new initials using my recently 
christened h/b 8877 amplifier.
Something didn't seem right with the amp tuning and I quickly discovered 
that the SWR was terrible. A continuity check on the TX feedline in the 
shack showed a dead short. Today I climbed up the tower with my 
multimeter and quickly discovered that the relay was the culprit. Some 
slightly blurred photos below (too many Molsons' last night hihi !).

I thought the Dow Key transfer relay was good for 1700W at 144MHz 
according to the datasheet but evidently not.

So I'm looking for a replacement...doesn't have to be a transfer type.  
A SPDT would suffice but it must be capable of handing at least 1500W 
with a 12V or 28V coil.
I can pay using Paypal. Anyone ?

Merry Christmas & Happy New Year to all !
