[TenTec] Problem with Hercules II

[Mike Cumbo]

Hello Wolfgang,

 Great amp, love mine. Does the problem exist on all bands or just on one band?

Subject: [TenTec] Problem with Hercules II

Hello:

I have a problem with my hercules II. When switching from transmit to 
receive there is a loss of sensitivity. The problem is intermittent. 
Keying the amp a couple of times the sensitivity returns. Problem exists 
with keying via VOX relay and also with QSK mode.  Switching the 
amplifier off brings the sensitivity back at once. I think there is a 
problem with a contminated contact in one of the relays in receive. The 
Kilovac K41C vacuum relay in the output was o.k. After instaling a new 
relay the problem still exists. Maybe one of the relays on the Input 
splitter board (81430). Probably K3.

Any ideas?
