Does anyone knows what happened to my amplifier? When I transmit, I heard a loud noise and notice my Plate HV/IC Meter was burnt, the meter needle was gone, current resistor was burnt, R10, R9 resistor open (.6 Ohm) and both fuses open. What I noticed that diode D16 was not there and missing. I have been using the amplifier for almost a year with out the diode. I contacted Ameritron and inquired why the diode was missing and no help, he said it should be on the board. A year ago when it is still warranty, I sent it back to replace one fo the tube and the technician mentioned to me that he did something else. I did not bothered to ask him. Did anyone experienced this issue and maybe guide me on what to look for after I replace the bad components?
