Good morning all,

I am on the look out for an AW22 speaker for a Radiola 611-T 7" with 1100 ohm field coil. I believe it has a 3 ohm impedance speaker coil and attached O/P transformer.

If anyone has such a beast they are willing to part with please email me with details.

That looks odd? Normally the bigger ones were 6 1/4" then 8"

I think I repaired a 611 & a couple of others around it, at some stage, I know where a couple of them are, I may be able to check? Hard to remember when you have repaired hundreds of sets.

Hi Marc, how are you?

Just measured the cone 6.75" and 7" to frame edge. Manual states 7"

The field coil is open circuit but not at the ends of the coil and the cone is torn and rotted, the O/P tranny seems to be ok.
If I cannot get one then I will replace it with a PM speaker and find a choke for the power supply.

A lot just use a WW resistor as a sub. I squared by resistance applies, to get the wattage it has to deal with.

Of course with most Australian circuits, they do not have the decency to be like a lot of the German ones and list element & rail voltages, & currents to make the serviceman's life easier.
