Time for the weekly puzzle..

This wooden console has 3 knobs (Tone, Tuning, Volume) and a round 0-100 dial. The plastic(?) around the dial is octagon shaped, as are the knobs.

Valve line-up: PM57 (57 equivalent), 58, 57, 2A5, 80.

There's a numeric serial number but no other markings or brand names. The chassis is sprayed blue. The top has turned into rust, but the underneath is still fine. The dial is a perfectly-working friction drive and has a lamp above.

The caps mostly need changing out, the thing works but it took about 5 minutes before reception started.

Someone went to a lot of trouble to fix the cabinet to make it look quite presentable.

The PM57 is made by Mullard and is probably a replacement, as its shield has gone missing.

Those particular goat shields may be a clue.

I can see that nobody has any idea about this one.

My first thought was maybe a kit chassis from Radio and Hobbies, but the console cabinet looks to be made by a cabinetmaker.

Again, that style of goat shield is unfamiliar to me and I would have thought they make a good clue.

There appears to be a couple of stickers on the chassis rear panel, can we have a better look at these, please.
Also, the small toggle switch on the front left of chassis is odd, inaccessible when in the cabinet and is a much newer vintage than the other components. What does it do?

I've just found a very similar looking radio in in 1935 Radio Trade Annual.

Unknown Console Radio


The dial assembly is a EFCO "Aero" type (EFCO Manufacturing Co. Ltd., of Arncliffe, NSW) & the knobs are "Duperite" (Dunlop Perdriau Rubber Co., of Melbourne).

Not sure about the valve shields (Goat is a brand name) but the I.F. & coil cans are made by Acorn Pressed Metal Co., of Camperdown, NSW.

.Gandhn: the sticker is just a notice warning of the dangerous voltages within. Only the top portion of it remains. It has no clues of the maker.

The switch is in series with the capacitor just to the right of the 2 red resistors. I operated the switch and there was an increase in volume and treble. I didn't look to see what that capacitor does. The switch is definitely a recent add-on.


.MonochromeTV: thanks for the image... the radio shown there is similar (dial, knobs, pattern cut), but not the same. I guess they are saying it's a Weldon... but maybe not.

(Goat is a brand name)

Yes, but it's long been a generic term.

That said, those shields do not look like the pressed metal ones made by the Fred Goat Co.

Marcc has seen the occasional chassis over the last 40 or 50 years. Does this goat shield ring any bells?

Very similar cabinet indeed, but your dial sits lower and the base is different.

This may be American made under licence to avoid the problems with Australian content?

The genuine "Goat" shields that I have seen, have it stamped on them & I have not seen others stamped. It normally consisted of four pieces.
Two sides, that close fitted an "S" type & one with a groove for the "Fly lead" to the top cap, a keyed pressed metal strip that on octals would only engage the spigot & pin1 and a clip to hold the two halves together. That one I have had problems with on a 6D6 but not always with 6U7 which is the same valve with a different base.

The cans on this are likely rolled, EMMCO made radio parts & that is not the latter design of the Australian Stromberg Carlson Gang that many Australian sets had. Henderson made transformers like that one; EMMCO would have made their own. Crosley & SC are American brands however the SC here tended to work independently from USA.

The goat shields that I have seen are made of steel and can tend to rust.

The cans in this radio are a one-piece aluminium, that is just large enough to fit over some spikes at the chassis level, which provides the earthing and the support. It gives a good snug fit. The photo may give the illusion of a circular clip, but it is actually just a step in the metal.


You can see the spikes around the PM57, because it's the one whose shield is missing.
