Sounds right. I installed the radio last year, but can only listen to it through the tannoy. Im in the process or rebuilding the 4 headsets used in the vehicle so the intercom can be utilized.

Chris.

In Bruce's first post on this thread, last photo, the image is the information plate inside the cover. The section dealing with the loudspeaker states the two terminals marked '19-Set' are connected to windings of 30 ohm value to match the output from the I/C amp in the 19-Set, if that helps at all.

It does.

The loudspeaker is obviously a rather heavier load than a couple of headsets, so needs to connect to the IC amplifier rather than one of the set outputs.

The Control Unit 190 is an odd beast with a single droplead for the wireless operator, so everybody else must be using the intercom - either via Junction Distribution boxes (No.3 or No.4 because the Mic+ line feeds into the IC amplifier so it can't be for the power microphone) or the loudspeaker (presumably once the gun is deployed).

Chris.

Default Tannoy

What is the average price of the loudspeakers. Original paint complete. No strap. All lock hasps there. Original marking with stamp. Arrow with p beside it. Getting rid of a pair but don't want to rip anyone off.

Something like that should just be free..... Really though; someone who knows the market chime in so he knows what to charge me. Jesse.

Jesse,

Can I ask you where you got the wiring diagram plate for the radio compartment junction box? I have been looking for one for some time now.

thanks, Perry
