[Johnson] Viking Thunderbolt

[Steve H]

Turns out I located some chip type resistors for my input load tests, so 
dont need the resistors anymore.

I began painting the rear cover, some photos here:

Ran out of flat black, so some areas are not as good as they could be.

Since this is now a fairly modded Thunderbolt, I thought if the cover was an 
off-purple
like a Muave or Eggplant shade that meets the original Johnson Burgundy half 
way on the color
chart....a little red in the purple to deepen it, would be a good pick if I 
can find the right color.

The flat black I guess will be more or less the primer coat from here.

Still need to fix the issue with the grid choke smoking though, but I am 
being optimistic that
cleaning up C2, the neutralizing cap which was loaded with soot may resolve 
it....or the new resistive input
network of 200 ohms, not 350 will also help.
