Amp supply and Dentron always had trouble with DIP relay failures
in the ten meter position of that board when used for heavy CW
use, like contesting. This was especially true with tubes having a
lot of input capacitance or low driving impedances.
Other than being unreliable with high duty-cycle ten meter
operation, and an occasional problem on 15 meters, the boards
worked quite well.
