[AMPS] LK500-ZB Amp Supply ...help

[Roy Koeppe]

Tony,

I don't have that info anymore. But put your VOM on say 5 amp scale, DC, and
use it to pull up the amp's relays with. See if it kicks up violently at
first, and then read the holding current. At any rate, it is way too high
for a direct connection to rig. Make a solid state relay driver or pull the
amp up an alternative way.
