[Jack Brindle]

Let me answer this one by saying that the designers at Elecraft indeed are amateur radio operators, but they are some of the best and most professional engineers I have had the pleasure of working with. The same goes for the other folks who keep things running.

The proof here is in the pudding. Have you seen any issues with the power circuitry in Elecraft products?

Didn’t think so.
