CHALLENGER III

The Challenger III uses a Russian GS35 ceramic triode valve.

This is a very rugged valve,which is capable of producing high power for long operating periods.

The Challenger will cover all the HF bands,10-160m with separate band positions for the WARC bands.

There is a massive 2.2kVA toroidal transformer producing 3600V after the voltage doubler board.

Cooling is forced air from a Papst flatpack blower located just under the transformer.

The Challenger III features a newly designed control board, which provides protection for grid over-current, plate over-current, over-drive and internal valve flash-over.

It also provides soft-start,warm-up timer,sequenced relays and high speed switching relay.
