[Elecraft] K3 power supply recommendations

[Eugene Balinski]

Another vote for the RM-35. I have had mine for over 30
years.  Not an issue. 

Note however that Astron over specs their power supplies.
 They claim that the RS-35 will do 25A continuous.  It will
not.  It gets too darn hot.  Given the heatsink, it should
do about 20 continuous.   This is with static air cooling,
no forced air. 

That being said, the RS-35 powered all 12 volt equipment in
my shack including the 120W HF radio, TNC, 50W 2m radio for
packet and dx cluster, and any othe vhf or other radios
that I wanted on.  I have seen the ammeter move past 33A
when the SSB voice peaks combine with the transmit cycle of
the packet radio, with no issues.
