   No.
   I am rebuilding a 2 X 813 amplifier that a friend gave me, mostly updating the power supply.
I plan on using Belden 8866 Ultor wire, that 3/16" red stuff that goes to the bell of the CRT, it is 
rated for 40 kV.  I plan on "lacing" a ground wire to it with flax lacing twine.   It will go 
through insulators at both ends and possibly secure at the amplifier end with red High temperature 
silicone sealer.  I planing on using ceramic stand off insulators and #8 machine screws (using ring 
terminals) at each end as the "connectors."  It is a 3.6 kV (unloaded) supply
