Well, my personal solution to the problem is simply to make sure that any amplifier, transmitter or any amp parts that I sell only go to licensed amateur radio operators. At flea markets I'll have a

I have looked at some of the other sites for amp parts and find that they have seemed to have evolved to CB junk and audio amplifier stuff and of very little use to me. If there is a good site for am

The first is why do most wide band common cathode triode amplifiers use plate neutralization and not grid? Usually they have a dual capacitor in plate circuit and not grid. It would be a lot easier t

I actually talked with the gentleman for a while at the Hamvention. He is actually getting orders and I admire his ethics. As most of us know 95% of the amplifiers that will operate on 10 Meters are

It seem that most of us have forgotten that resistors have another limit other than max. power dissipation. That is a maximum voltage rating . It seem to me if that rating is seriously exceeded there

A swinging choke is a cheap form of open loop voltage regulation. As the current increases the inductance decreases this increases the voltage on the following filter capacitor. In essence the filter
