[TenTec] Omni VI Plus audio

[Duane Calvin]

Tim,
	As I remember it, there was a fair amount of ripple in the passband
on the VI and VI+, and the Inrad mod is a couple (more?) of capacitors that
were designed to help flatten that out a bit more.  I bought the mod for my
Omni VI+, but ended up selling it to buy an Orion before I installed it, so
never got to see what the difference was.

	73, Duane

Inrad doesn't give any detail on the mod. Can anyone shed some light on 
just what is being done ?
