Wanted: WS19 No3 control unit

[Bruce Parker (RIP)]

Yes, an amazing early British set from a very hard to find maker. Well done!!

It's British (and the company is still operating, mostly as a Defence contractor, I think). They also made photographic equipment: Agiflex and Agifold cameras, Agiphot enlarger, etc.

Unless you use an extension cable on the droplead, I think you are going to have severe difficulty in mounting the control unit and Junction Remote Control close enough together - although the control unit was mounted flat on top of the set in the Daimler Dingo, so if there is room you might get both of them on there. The other problem is: where does the remote cable reel mount? If it's on the turret then you need a feed through the rotary base junction (if fitted), or to connect the JRC to a droplead when required for use - it also needs a 12V supply for the relay to work, and I think the green light may have to be visible to the wireless operator when in use.

Best regards,

Thanks Chris and Bruce.

I've done a lot of measuring of the space that's left in the turret and I just don't think there's enough space available for the remote control unit next to the control unit. May have to ponder that one a bit more.

Chris - the driver is indeed provided with a No1 distribution box (as per the
attached picture) and is connected via the vehicle wiring system. The DAC has a crew of three so the commander and gunner are serviced by the control box in the turret.

Looking at the wiring diagram I assume that the connections for the distribution box come from the 6 pin plug on the power supply unit. I'm guessing then that I need a special power cable for this, one that has both a 12V power supply wires (+ & -) plus speech and signal wires. Add that to the "I need" list I guess.

You will need a different power cable with additional wires in side.

On my Humber AC I wired in the power mic box used on he tanks so you can still talk even if the radios fail. Obviously the driver needs a carbon mic powered by the transformer in the Number One Distribution Box.
