[Elecraft] Schematics for KPA500 REV "B"

[Andy Durbin]

"I have a PA board with "REV B" "silked" on it, but the schema I was supplied with is for "REV A". I know there are differences."

I received KPA500 schematics from Elecraft about 2 years ago.  This set includes sheets that are at rev C and rev D but the sheet "KPA 500 PA Module" is rev A.

KPA500 LPF Bank, LPF Control, and TR Switch are all rev D

I don't know the history of changes to the PA board but it would be possible to have a change to the PCB that did not require a change to the schematic - e.g. elimination of corrections made by cuts and jumpers.

If there is a later version of the sheet "KPA 500 PA Module" I would like to have it too.

(Pedant alert - The schematic really is titled "KPA 500" with a space, not "KPA500")
