 When all is well, the resting plate current should be zero or nearly so with no excitation. ​ Whether in QSK or PTT/Vox mode, standby or operate, the current should be zero.  If you key the amp via PTT or QSK with no excitation, the plate current should be around 100 ma.  Before, the outside cabinet temperature where the tube exhaust air leaves the cabinet was 198 degrees F.  After the fix, the cabinet temperature at that point was 98 degrees F. When all is well, the resting plate current should be zero or nearly so with no excitation. ​ Whether in QSK or PTT/Vox mode, standby or operate, the current should be zero.  If you key the amp via PTT or QSK with no excitation, the plate current should be around 100 ma.  Before, the outside cabinet temperature where the tube exhaust air leaves the cabinet was 198 degrees F.  After the fix, the cabinet temperature at that point was 98 degrees F.
