Default Re: The Wellgood Magloop Amp

Deciding to side-step the thermal issues by running the amp at 10V, I'm now sat listening to some some G stations and some D stations working each other on 80m. The background noise level seems to be low and the S-meter is hitting the end stop hard with some signals. The receiver is a Realistic DX-160 and the 1m loop is in the shack (bedroom), a couple of feet from my running desktop and inside a house with numerous wall warts.

Brief excursions up to 12V, and then back down as low as 6V makes no audible difference. At 10V, I=107mA.

That's quite pleasing.
