I just looked at RF Parts. They have a matched pair of 3-500ZG (3-500ZG =
RFP) for about $255. I think that they are Svetlana tubes. The price =
is excellent. Are these good tubes? They also had some Amprex but at a =
much higher price. How about Taylor 3-500s? Where are these tubes =
made?. A pair of these is even cheaper ($238). =20
I understand that the graphite plates will dissipate more power. If one =
gets these tubes, does one increase the plate current to match the =
increased dissipation? That assumes that the stock power supply will =
handle the increased power. From some of the comments, I think that it =
might not. What is an HB supply? Is it a brand or a design that one =
home brews? =20
