Pianocorder Documentation

WARNING: The Pianocorder Reproducing System is a "hot chassis" device containing dangerous and potentially lethal voltages. The technical portions of this documentation assume the reader has a basic familiarity with electronics and knowledge of safety procedures involving high voltage equipment. It is strongly recommended that you consult a qualified technician to service your Pianocorder, and by downloading these documents, you accept all liability for damage or injury caused by working on the system yourself.

All documents on this page are in Adobe PDF format.
To view them, install Adobe Reader, available here:

Since some of these files are quite large, it is strongly recommended that you download them first before trying to open them. To do this, right-click on each file you want to download and select "Save Target As...".

These files will take a LONG time to download over a dialup connection. I am willing to supply the files on CDROM if you send USD $4.00 to cover materials and postage. If interested, contact me by email at the link below.

Please do not attempt to contact Superscope/Marantz at the numbers and addresses listed in these documents; the Pianocorder division was sold off back in the late 1980s. For parts, service and repair, consult this list of Pianocorder technicians.
