Old Crow's Synth Shop: Polysix "Mini" Service Manual
I have two versions of the Polysix Service Manual: the standard version
with the 11x17 fold-out pages of schematics and board trace maps, and a
"mini" version I made to condense the schematics onto single pages. The
mini version is presented here first as I need to figure out the best way
to present the big fold-out pages of the standard manual (my scanner isn't
big enough for 11x17 size paper). The standard version will appear on
this site once the format for the large pages is decided.
The "ink blotches" in the text portions of this mini service manual are
really from a colored highlighting pen. I could have scanned these pages
using greyscale or color, but the OCR/text mode of the scanning software
produces much better results, and I used this to make it easier to
read. Some of the schematics may be difficult to read due to their
size vs. the page constraints; this will be much improved in the
standard version of the online service manual.
All files are in pdf format; get the free Adobe Acrobat Reader if you don't already
WARNING: Do NOT attempt this calibration procedure unless absolutely
The standard version of the service manual--which includes the circuit
board trace maps--will be made available at a later date.
