Hi anybody out there that could tell me what the coil resistance of

the Trio
TS-500 transmit/receive relay is, it's missing in my renovation

project.
It's driven by the triode in a 6BL8 valve which has 150V plate

voltage. I
guess its high but?


I am not at all familiar with the TS-500 ,but ,I think you need a

plate
relay ,as used in Vox circuits ..it will be high resistance like 2 to
10 Kohms..Usually they have a circuit to adjust the "pull in "

point..
I also believe you can find one at Fair Radio Co. Sorry I don`t have
the stock # ..GL 73 Harold W4PQW.


Fair Radio has it at their website part is P&B KR-4175 @ $2.00
should work OK I have used them W4PQW
