[Heathkit] SB-220 Load Cap Bigger Than Stock ?

[jeremy-ca]

Heath used two different Load caps. The original was a 2 section TRW of 
400Pf per section. For cost reasons they went with a single section 800pf.

If you search the web you will certainly find interior views of both.

The only reason to install a larger one would be if the original arced due 
to a poor antenna VSWR.
