Hi Guys:

No progress to report. My wife discovered she could use ear buds instead of the headphones and she has been happily (and quietly) playing the feaux piano (my old 2000 arranger) off and on all day. She won't give it up long enough for me to perform my "surgical inspection."

I did attempt to use the microphone by plugging it into the back of the 2000 after removing the headphone "dummy jack" to see if any sound might emanate from the speakers in that fashion. No luck. Dead silence.

I also tried the trick of plugging in and removing the dummy jack into the headphone connection rapidly and repeatedly. Still no sound from the speakers. It may be days before I get to find out if the board is the problem... but I will let you know what I discover if I ever get the opportunity to open it up.

Thanks again for your suggestions and interest,

Dave Rice
