[Henry] Henry 2K relay problem

[David L. Thompson]

Dick,

The transceiver is an even older IC-740.  As far as I can tell the relay
circuit just opens or closes (to key) the amp and thats all the Henry is
looking for.  I have used the IC 740 with the amp for several years.   I
still have the old time delay relays but have long since replaced the 3B28's
with solid state stacks (wihich put out 100 to 200 moves HV and are much
better in voltage drop).  I think I have the relay working and have found a
replacement
6N02 to try.  For now I switch on the HV toggle switch, turn it off and
right back on and the amp keys.  Thanks.
