You may want to try Organ Service in Chicago. Check the MITA (musical instrument technician association) web site for his address and phone number.
There are also other people in MITA who can help you with this problem.
Best of Luck,

I am looking for an IC for a 70s/80s vintage solid state Piper autocord 100/730 organ. Specifically I need Hammond part number 075-042148 which is a 6-stage divider IC. PD-455 is the generic equivalent. If you have one of these in the junk heap I am looking for the lower oscillator board or one of the above mentioned chips. These chips were probably common throughout Hammond solid-state organs of that era. Any help anyone can offer locating one of these obsolete components will be appreciated.
