[Elecraft] KPA500

[Jim Wiley]

Not to mention the time one of the diodes in my Drake L-4B amplifier 
power supply decided to let go under load  - -  sounded like someone had 
let loose a 12-gauge under the operating desk.  We're talking LOUD!


Or the time one of the (tube) finals in a  Drake T-4XC  went South - I 
was on 20 CW at the time.  One heck of a light show from the back of the 
rig, but the thing was still making power, so I sent a string of AS AS 
AS until it finished cratering and blew the fuse in the PS-4.  Then 
switched to a backup rig and finished the QSO. 


Them were the days.
