Linear AMP UK - 50MHz Discovery 6 (GS35)

For Radio Amateurs that need effortless, reliable power for contesting, DXing or EME.

The NEW Linear AMP UK  Discovery 6 uses a Russian GS35 triode which will produce up to 1500 Watts with about 100W of drive.
The unit uses a 2.2kVA toroidal transformer with a high power voltage doubler HT board. 
Control and protection circuits are all provided by the specially designed control board. 
The cooling is a snail-type fan which blows into an aluminium RF compartment. 

Quiet changeover relays, anode protection and auto soft start are standard features make the Discovery SIX very easy to live with and quiet, efficient and effortless in operation.

Full output can be maintained all day long for EME, Data Mode and contest operation.

NOTE we can also build this with an 8877 (3CX1500A7) valve as an extra cost option - this higher gain device will give 1500W out with just 65W drive. Click here for details.
