K3: KPA3 100w amp

[DOUGLAS ZWIEBEL]

Other than the price, have there been any changes to the KPA3 module
(and associated parts/fans) since it was first introduced?

Minor changes in some component values is my understanding.

I am still using the original PA in S/N 2 (pre-FT).

There were a few units that "escaped" with a capacitor (C3) that should not have been installed.  If you're buying a used unit, you might want to check for that before installing it.  See below:
