[Heath] DX-60B Update

The replacement parts for the DX-60B arrived today, R35 the 270 ohm, 2W
resistor, R34, the 100 ohm 7W resistor and C19 a 0.001uf, 1.4kv disc
ceramic cap, all of which are in the power supply circuit.  I installed
them all and proceeded to the test phase.  Everything went according to the
manual as far as the tune-up was concerned.

Measuring the output, the rig is putting out about 45 watts to a dummy
load..  The spec says the input power is 90 watts so I would think the
actual rf output should be around 70-75 watts.  Not sure why this is
happening.  I'm getting the proper grid and plate current to the 6146 which
tests good with a tube tester.  Any ideas here?

Anyway, it's good to have the old girl running again and I really
appreciate the help I received.
