[Elecraft] Power Supplies

[Vic K2VCO]

This isn't an answer to the question, but a comment about Astron linear power supplies. I 
have twice seen a situation in which the screws that hold the circuit board to the 
capacitors work loose over time. The resultant heat can damage the board. It's a good idea 
to check that the screws are tight every few years.

Having said that, I've found these supplies quite reliable otherwise.
