Hi Phil,

This set is in Riders 11 page Emerson 11.  I had to search 
on CY(space)288 to find it.  The electronic copy is 
difficult to read.  I'll scan the original if you need it.

You'll want to tweak the oscillator padder condensor, C4, to 
align the low end of the broadcast band.  (Trim high - Pad 
low.)  The "padder" is IN SERIES with the oscillator coil. 
from it's "cold" end to ground. I'd expect a compression 
variable cap with lots of plates.  The "trimmer" is in 
parallel with the coil/padder combination and aligns the 
high end of the tuning range.

Regards,
Al
