[Heath] SB-1000 high swr on transmit.

[Glen Zook]

The 3-500Z is infamous for leaking around the pins and if the tube has not been operated for a year, or two, it is very likely to have gone bad.

Hello to the group.  I am putting my SB-1000 back on line after a few years of 
no place to operate.  With nothing having been done to the amp, I notice that when the amp is on standby, my swr into my steppir on 40 meters is 1.1.  When I put the amp in line and go to tune, no 
better than 9:1 to 12:1.  I am driving with Elecraft K3 and keying with the 
elecrafts keyer.  Could the tube have gone bad from sitting?
Thank you for any suggestions to start looking.
