If you ever need to work on the Ohms circuit of a Solartron 7150 Plus, be warned, there is a schematic error in the service manual.  In diagram 2.1 (PCB1, Floating Analog), the top of resistor R22 should connect to the Source terminals of TR4, TR9 and the top of R26.  This "wire" should NOT connect to the gate of TR4 as it appears to do in the schematic.

I couldn't work out what was going on here for a while, and then the penny dropped!

The schematic in the original 7150 Service manual is correct.

Regards,
David Partridge
