The Explorer uses two 3-500ZG valevs in grounded grid configuration, and along with a 1.2KVA toroidal transformer gives continuous operation for long periods, even on RTTY. Pretuned input circuits are incorporated on each band so that your transmission sees a 50 Ohm input load on each band.

This design from Linear Amp UK with high specification and rugged construction has features normally associated with expensive linears. However, this model is offered at a very realistic price and it will loaf along at the UK power limitation. The low cost power tubes mean that tube replacement will not break the bank.
