Hello All:

Here is a neat tube made the Soviets at Svetlana. Heard a lot about
these tubes. Anyone using anything like this?

Tube spec's at: http://www.qro-stuff.com/gu-84b.pdf

The neat thing about Tetrode Tubes, is that it can be designed to have a
low input drive requirement for full output. With a step up transformer
and a resistive load on the input circuit of this Tetrode Tube. The
Pride DX-300 uses such a circuit with a 4CX250. So no driver is required
as the Triode Tubes in a Grounded Grid design.

Anyone using one of these tubes?
