[ Next Thread | Previous Thread | Next Message | Previous Message ] Date Posted: 11:28:01 12/03/03 Wed In reply to: Michael Herklotz 's message, "Looking for Circuit Diagram of P-100 PC" on 07:16:28 12/03/03 Wed Mark Fontana has put a great deal of Pianocorder documentation on CD-ROM, including schematics. Check out his latest post to this forum and visit his Pianocorder web site regarding availability. Several things go wrong with the power supply which are not well-documented, however. Use of a too-small extension cord can take out the 5-volt supply's bridge rectifier, for example; the varistor in the 170-volt supply for the solenoids can fail, resulting in a blown 10-amp fuse and/or lots of arcing and spitting at the power switch.
