[Elecraft] KPA500 problem

[Don Wilhelm]

Jim,

I think you will find the KPA500 transformer to be quite robust, but of 
course there is always a small chance that you have one that could be 
defective.  If you can monitor the DC voltage under load, that would be 
revealing.
Contact K3suppot at elecraft.com or Jack Brindle (he has already responded 
to you and is one of the KPA500 designers).
