MOPA Transmitter in Stew Perry (TBDC) Warmup

Running a newly built 1930s style MOPA transmitter in the Stew Perry (TBDC) Warmup this evening.  The transmitter is running a 89 Clapp oscillator, 802 buffer, 811 final; one of my favorite tube / circuit lineups.  Output power is approximately 75W.  The rig is keyed with a 1962 Vibroplex Champion.
