I have a Ten-Tec Model 253 KW Automatic Antenna Coupler for sale.  It is 
not working. 

I am positive that the only thing wrong is the main T/R relay, a vacuum 
relay that is no longer available under its original part number.  I 
strongly suspect that the unit took an induced lightning surge, since 
there was also damage to my Omni VI at the time.  When the Omni was 
repaired, I discovered the problem with the tuner.  The tuner relays 
operate, but do not reach a low swr, even tuning into a dummy load.  
Further checking inside showed that the main relay is not operating. I 
tried putting voltage directly to the relay coil, and the relay did not 
operate.

I used this tuner on all bands at 1500 watts output, as long as the 
mismatch was not too great. 

I no longer run a KW, and I do not want to spend the time finding a 
replacement relay.  I would like $300 + shipping for this unit.  I have 
the operating manual.

Jan, KX2A
