[TCML] GU5B VTTC rebuilt

[Liviu Vasiliu <teslina@xxxxxxxxx>]

Hi

I made a few grid network modifications preparing the setup for full CW (I collecting parts for a new power source). I am runing now with a 0.56 Kohm high power grid resistor (made with different size high watage resistor). The tube runs cool (it is safe to put the hand on the anode 1 minute after fillament shutdown, with the coolers on)

I hope to finish the new source maibe in a week (just currious how it behaves in CW).
