Polysix Service Manual Error list

Polysix Service Manual Error list

2014-11-07 by f115@rocketmail.com

Hey again everyone!

Is there a list of known errors in the service manual that anyone has posted? I'd like to mark up my copy. I've periodically read that errors are there but a definitive, shared list would be fantastic. I'll compile something and post it to the files section once we're all satisfied we have something reasonably complete.

Thanks in advance!

Here’s a list I posted here back in July 2012. I still don’t know if it is complete.
 
1) On IC30,31, pin 5 in connected to +5v, not pin 4.

2) IC30 ground pin is pin 7, not pin 1.

3) The 14042 below IC26 is IC24, not IC34.

4) The capacitor connected between R28 and pin 6 of IC3 is C5, not C4.

5) The diode on pin 9 of IC29 is D13, not D12.

6) The diode on pin 15 of IC29 is D14, not D13.

7) The signal from pin 7 of IC14 is MG Level, not MG Speed.

8) Capacitor C33 is connected to the collector of Q5, not the other side of
R98.
