Many thanks, Jason.

I took another look at my PK3 and discovered, as you say, the pin=20
drivers are in a SOT-23-6  package.  I'm not sure why I thought that=20
the pin drivers were the smaller chips on the board.  All I can say=20
is that it was late, I was tired - and probably a little punch-drunk.

Anyway, I now have the parts in hand and will be changing them out later to=
day.

Thanks again!
