Henry reduced the dissipative burden in R-supp 100% in the 8-K Ultra
by adding chrome plating to L-supp until the right R/L ratio was reached
for the 3CX3000A7 layout. Several scoffed and threw rocks when I mentioned
this innovative piece of engineering earlier in the "grate parasitic debate."
Has anyone ever heard of any parasitic problem in an 8-K Ultra? I have had
several of the Henry suppressors in use here for years....no problems.

IMO, anything less than a 15 watt R-supp on anything larger than a 800 watt
dissipation tube is under-engineering for an amp that is going to be used
a lot on 12-10 meters. Been there, done that, stunk up the shack!
