Greetings to all. New member here. My amp no longer gets warm ever. Red and green lights work and I checked the fuse and it seems ok. No contacts since this issue came up. RX is fine. Also when switching on the amp I no longer get the slightly higher background noise it gave when first installed. Less than a couple of hours run time on this unit. Hardly ever use it for TX. Any easy checks or is this pretty much a throw away situation?
