Forgot to mention that when powered up it was very noisy somewhere from the mechanical drive, noise did not get worse when Play or Fast Wind selected.

Traced problem to the rubber tyred friction wheel that is driven from the motor pulley and then it drives the flywheel when a tape speed is selected (tape speed selection also switches power on).

Found that when the friction wheel was manually pulled back so not contacting the motor pulley and flywheel, the noise then went away and the motor and upper idler wheels that were still rotating were pretty quiet. The flywheel was smooth and quiet when manually rotated, but the friction wheel when manually rotated was stiff and graunchy. Lifting the copper sprung arm that holds down the friction wheel, enabled the friction wheel to manually easily spin, then realised that the sprung copper arm was in the incorrect position over to the right side, in first photo can see where it has worn a mark on the top of the friction wheel.

Moving the copper arm to the correct position in the middle of the friction wheel as per photo 2 (it sits on a nylon dimple) completely eliminated the noise.
