 AMPHF - Need help with THP -1.5 KFX not keying
- My THP AMP stopped keying with my IC7800. The amp tracks band changes, fan working, no fault LED’s on, cables connected not loose. Could the issue be an internal fuse, bad transistor on relay/PA board. Problem started suddenly.
Does anyone know a ham who works on these THP amps? I live near Philadelphia.
Any advice would bee greatly appreciated. Thanks
Bob
