Hi Carl,
The 60B uses grid block keying. As I recall there is a halfwave rectifier
ckt that provides something on the order of -80VDC to cut off the final
during key up. You might want to start there as it sounds like that supply
is not working.

Been trying to get a Heath DX-60 going. Here's what she does: It loads
fine to the proper grid and plate current however when the key is up the
current jumps to 200 or more ma. Then when I key it, it drops back down to
the nominal 120 ma. Ive checked everything but am missing something. In
the grid position it shows no current except when the key is down and
peaking the grids is normal. But when I switch to TRANSMIT the plate
current goes to over 200 ma and stays there until I press the key to
transmit; then it comes back down to normal values. I've swapped with new
6146 and checked the 6CL6s...all good. Any ideas? Tnx Carl
