If it does make power, you have lost your cut off bias voltage and will have to trouble shoot that circuit. If both tubes are glowing about the same color, good chance the bias supply is your problem or your bias voltage switching. 73 and Happy DXing, Mike W2AJI Tryon NC

Or the keying line is stuck keyed to transmit. Might be a cable or the
driver, not the PA.
