[600MRG] WD2XSH/6 transmitter failure

[dave.riley3]

add:

RG8 is about 17 pf per foot ( styrene type ), so pre figure length and 
then some, connect, then clip to tune ( with power OFF fer sure )...
Use both connections at one end, other ends open, not connected for EZ 
cut...

With power off, tune final tuning cap with good load on final to see 
minimum final grid current change...
Yes, driver connected and hot, final HV OFF, this will let you tune 
neutralization real fine in safety...
