Here is an instruction video of the tune up procedure I use with a Heathkit DX 100 AM transmitter.
This transmitter is more than half a Century old and is still in perfect operating condition. It has been cleaned, repaired and restored to operate like the day it was made.
Climb on board the AM wagon and enjoy the nostalgia and fun.
This video was made for the experienced Ham who does not have a background in tube equipment.
