Re: [TCML] Wanted (6) 8020 Vacuum tubes, RF filtering

Your 16 inch valves certainly seem sexier than Syd Klinger's 1000 x 1N007's 
to rectify his 3 phase 170kVA for his Cauac TC.  You can see an inductor as 
part of his RF decoupling in the DC line to hs coil.

Syd's diodes were well proven but I know Carlos (Lightning for hire in NZ) 
blew a set of HV diodes on a 20kVA system so used an AC system for his 
display.
