[Heathkit] SB-200 10M Input Coil Question

[Carl]

Manuals 595-682, 682-2, 682-4, 682-5, 682-12  has just a 68pf on the output 
side as C-38.

I have a couple of loose schematics with no reference # that show C-38 as 
115pf and a new C-39 as 290pf on the input..Since these show C-19 miswired 
I'll "assume" that this is an earlier version.

One popular mod is to change C-38 to 100pf and reduce the coil to 3 turns.
