Turned on #121 tonight. Keyed K3 with 15 Watts. Amp immediately went into hard fault mode showing ‘50 VOLTS: 4.5 volts’ recycled and relayed. Immediate hard fault showing ‘50 VOLTS: 2.5 volts’. Next recycle fault shows ‘50 VOLTS: 2.1 volts’ Sounds ominous. Anyone have any ideas? 73 Steve AA4V Sent from my I-Phone
