Does anyone have an Astor OZ extension speaker change over knob?
There is a switch on the side of the OZ that switches the internal speaker to an Astor Minnie Extension speaker when plugged into the socket on the rear of the chassis.
Would be nice get a picture of the knob?
Thanks,
Gary

The label on the rear of radio refers to knob as a a "Remote Speaker Key", so perhaps it was an accessory when you purchased the Astor Minnie extension speaker.

Anyone spot the huge spelling error in the advertisement?

If you look into the hole for this key a short shaft is seen like that for rewinding a clock. It does not appear to be square however. So I think the key would be like a clock key, though perhaps not with a square hole.
I've got this radio wrapped up in plastic because of the asbestos heat shield, so I'm not inclined to take the chassis out of the case to check.

So, it's a rotary switch?

A lot of sets had Asbestos, one has to be cautious as to how it is handled and where. Anything that turns it to dust, or causes the dust to fly is a problem. Even a vacuum cleaner can causes particles to fly and when vacuuming shattered glass & Asbestos a full face shield is advised.
Naturally a respirator is also advised. I normally paint it with diluted PVA wood glue, as a binder. The less you can disturb it the better.

As that is a round shaft & the end indicates it has not been broken off we perhaps need to see another assembled to see clearly if the shaft is flush with the cabinet?
There are two thoughts. Its it a long knob with a lock screw accessible from the inside, or is there a hole through the shaft, which at some time had a pin in it and that was the "drive dog" for a forked key, that is easily made.
I think I know where there is one of these and I have had my hands on it.

The shaft on the switch does not look like it is broken. It sits 2mm inside the chassis. The chassis fits tight into the case so if the end of the shaft had been sheered of it could have only been about 5mm longer. Need to check with another OZ.
The switch is easy to turn. It is not as hard as a later oak type switch.

I can check on mine but it would have to wait until Monday night as I don't have the radio handy at the moment.
