PianoDisc driver boards

[Rob Kiddell]

Greetings, 

As a follow-up to my earlier PDS-128 Plus inquiry, I appear to have 
two groups of six solenoids that aren't functioning. I suspect the IC 
above the solenoid contacts, but I will have to check board solder 
traces first.

Can the IC's be replaced, or is it easier to get a new 90-note driver 
board?

PS: I've mounted the solenoid rail with 3 short at the bass and four 
in the treble, and attached the solenoids to the boards in that 
order. With the exception of the non-working solenoids, the system 
checks out.

Thanks to all who have replied, 

Regards,
