Look what a friend gave me. Need help to ID

[rob love]

On my recent roadtrip to Alberta, a friend gave me a bunch of WS19 set stuff. Some of it I recognize as regular WS19, but some I do not. He gave me an WS19 Amplifier and the table it mounts to. All 8 of the rubber mounts have broken. My first question is what or where did the table mount to? There was also an AC supply unit, and I think I have a couple of those out in the shed already.

Now for some more "new to me" oddities. The variometer has a different cord coming out of it. Was this a ham radio operators post war modification?

Aslo, the metal plate does not match up to the wooden block on the mount. The metal plate wants flathead screws while the wooden block is not indented to accept the plate.

Next photo is a lamp assembly, a smaller than usual dogbone, and a couple of little ceramic electronic items. Any help?
Third is one of the small dogbones next to the normal larger dogbone. I got about a half dozen of the regular dogbones, then some with the cord for the crystal calibrator, and the small ones with the cord for the crystal calibrator.

There was also one dogbone with a amperage meter spliced into it.

Next is a photo of some more misc stuff. There are multiples of most of it. I am guessing the green brackets with the neck and chest straps are to hold a microphone in the "stowed/ready" position?

Another box of stuff. It included one of the nicest spares box with key that I have seen. That will be moving into the carrier. Does anyone recognize the little test box, or what is inside the sealed box? The previous owner didn't have the heart to open the boxes, and neither do I unless it is something I would actually use. One shot shows the ID plate on the table.

Again, I am no radio collector. They are just an accessory to sit in the vehicle, so I know little about the oddball stuff. Please enlighten me.

No idea, may be specific to the Canadian amplifier. I've not seen that variometer extension before.

The block may just be a spacer because I think the variometer fits to the amplifier table frame so does not need an adapter plate

Small dogbones (6-pin - 6-pin) are for the earlier WS19 Mk.2

Lamp is the standard "Lamp Operator" - you remove the red lens and the bulb from the supply unit, screw the cable in instead, and clip the lamp somewhere where it sheds useful light without dazzling you.

The ceramic items are high-voltage silver-mica capacitors.

The dogbone with the spliced-in meter is a later bodge by someone.

Be careful with the AC power supplies: the 6X5 rectifiers are a weak point and if the insulation between the valve heater and cathode fails they can destroy the transformer.

Best regards,
Chris.

Thanks Chris.

What about the large silver cables that allow the plugs to be stacked? Are those also a amplifier item?


These were held in a technical college since the war, so some items may have been modified for their test purposes. Apparently the stuff was boxed up after the war was over and refound just a few years ago when they were given to my friend.

It's all Canadian Amplified No.19 stuff.

I guess I had better be looking for some parts manuals. It is not quite as easy as looking for regular 19 set stuff.
