[TCML] FW: vttc grounding issues

[earl rhodes <earl_1975@xxxxxxxxxxxxx>]

hi everyone
i realise there is lots in the archives on this subject but i still dont find a definative answer
some use mains ground others use rf ground
does the power level have some say in the matter ?
i 
 have used all the grounding options  and it is easy to change from one 
to the other but im not seeing any difference in performance from either
 setup
im using a 3.5kw gu-5b tube
and i say rebuilding the coil 
what i mean is i never finished the build in the first place and i 
damaged the table it was on it collapsed under the weight of the 
filament xfmr and the two mots so im rebuilding it and adding 
improvements as i go along
and my grounds are bugging me!!! which in your opinions is the best way to go
please advise!!

p.s a qiuck look round and also some testing videos are on my channel you can also see how its evolving as i go  along
heres the latest vid the rest are easy to find once you see this one

hello everyone 
i seem to be getting a little confused  with my grounding 
im building or rather rebuilding a vttc and im wondering which ground i should use do i use mains ground or rf ground
 to clarify my situation  my power is coming from a matched pair of microwave xfmrs one being driven antiphase to the other with the cores together (nst style)  my dilemma was or is ..that do i ground the centre and leave the output floating and rf ground the secondary coil
or do i ground the output of the microwave xfmrs and leave the centre ungrounded and again rf ground for my secondary coil
or  do i lift mains ground altogether and use rf ground for everything exept the centre of the power xfmrs which will be ungrounded
can you understand my confusion or am i just dumb
earl
