K5 in my Gates BC-1T was an Amperite 115 VAC glass-envelope,
octal-based time-delay relay with one normally-open contact. It was 30
seconds delay, so that would be a 115NO030. I found that both time
delay relay coils in the rig are actually running on 230 VAC (as are
all the control circuits) with a 6k resistor in series to drop it to
115.
While I was restoring my rig, I found the contacts on K5 "bounced" upon
make, so it would have an irregular start-up time and would sometimes
bounce three or four time before finally settling down. To fix the
problem, I pulled the relay, wrapped it in a towel, and smashed the
glass. Then I burnished the contacts, tested it, then glued a small
bottle upside-down in place of the original glass.
I found 30 seconds to be a bit long for the low-voltage enable delay,
so I ended up replacing the Amperite with an octal programmable
solid-state timer relay I had on hand set to 15 seconds. The K4 relay
for the HV enable delay was excessively long too, a couple minutes as I
recall, so I ultimately moved the 115NO030 to the K4 socket to become
the HV inhibit TD relay.
