Fan heater knob - detailed information.

[David WE Roberts]

to those who offered to look in 'stock' to see if they has a spare knob to fit.

My Powerfix electronic digital caliper suggests the following:

Shaft (D shaped) external diameter 6mm Knob recess internal diameter 38mm - although a sub-38mm knob would be fine.

I broke the knob on the temperature control and moved the selector knob across but it would be nice to easily select between off, cold, half and full power.

the year's offerings and locations. Or post in a ham radio group.
