In the current design, are the Power Genius XL amplifier switching relay(s) socketed and located on the amplifier chasis for access/field replacement? Being mechanical devices they will fail at some point. Customers may want to keep spares on hand. Contest QSK and QRQ CW require high relay reliability and good MTBF. In the case of failed or intermittent amplifier relays will it be necessary to ship the amplier to Flex for repair?
