I've read some of the service notes which mention to two large 3k and 4k wire wound resistors. The circuit diagram for the capstan motor shows three wires red, yellow and green, or red, yellow and mauve depending on which diagram you look at. Problem is I can only see two black wires connected to the motor from the resistors and that's it. It mentions a 2uF capacitor, but I can't see that either! Problem is that this is intermittent which makes it hard to pinpoint the cause.

Yes that is confusing Terry.
I can only assume that your R82 is not a full Mk. 2 (as referenced before) and its capstan motor is not the type that requires a Run capacitor, i.e. it probably is a Shaded Pole motor and hence only 2 connections.
