"So rest easy, if you were ever concerned about the clicking and clacking and what it might be doing to the quality of the relays. They will probably out last the K3 and certainly you."
The key word in MTBF is "mean". How lucky do you feel?
Relay failures, especially in tuners, can give faults that are quite difficult to trace. In the last few month there have been I think 2 KPA500 faults mentioned on this list that were attributed to stuck relay contacts. I am also aware of a recent TS-590 failure caused by a failed tuner relay.
Is your relay life half full or half empty?
