NorthernTelecom QSQM 500 A & AX Schematic
« on: October 27, 2016, 03:22:02 PM »
Good Afternoon All   ....   I scanned the schematic for a Northern Telecom QSQM 500 A & AX Rotary Dial Desk Set out of A Bell Canada Station Installation & Repair Manual (1981), and attached it in both "jpeg" and "pdf" to this posting.    They are now on file on C.R.P.F. for future reference.     A copy has also been sent to the TCI Technical Library.

Enjoy the rest of the day !

Thanks, Jeff.

Increasing the contrast just a little bit removes the ghost image from the reverse side.

And so it does !    Both the "jpeg" and the "pdf" attachments corrected.     Thanks Karl !
