Opened up the Input/Recording level control, took some force to prise it open. The in-operative wiper contact somehow fixes to a Paxoline disk, the disk is split in two. Considered trying to superglue the disk back together but decided the whole control is past being fixable.

Useful seeing the 2 sets of SPDT switch contact as after checking which contact connects to which external connection contact, this will help a lot later when I come to hardwire the switch's wiring, probably will opt for permanent automatic operation (automatic in terms of the tape automatically reversing at end of track 1 when recording, not automatic in terms of the recording level).

Could not fully open the other end of the control but could not see any obvious signs of the mains voltage On/Off switch contacts ?

Have made a start trying to identify the mystery set of contacts, which have 3 screened cables connecting to them. One of the cables (red sleeved) connects to a small pair of contacts on an arm that the pinch roller is mounted to, this pair of contacts make/close when the pinch roller moves to the Play position.

Have not yet been able to identify these pinch roller operation contacts on the schematic, the other side of the contact connects back to a relay but cannot work out which relay it is or its contact number.

Am waiting for a German Service manual (copy) to arrive, hopefully this will help in identifying these contacts, the German schematic I downloaded the other day is not good enough quality to be of help with the contacts.
