Gday Everyone,

I am new to the world of Radiograms, in which I have just purchased my first.
All I know is it is a Airmaster and it has a speaker that was made in 1947 any help would be great.

That's going to be an early radio. Looking forward to the pics. Valve line-up may help identify the chassis.

What do you intend to do with it?

(Must be pretty chilly up there in Katoomba tonight!)

Photos uploaded.

Not a radiogram, but a console radio. A radiogram contains an electric gramophone, usually situated at the top in the cabinet in the the early ones.

The set you have is slightly later than I was originally expecting before the photos were posted (missed the mention of 1947 speaker).

Radiomuseum says:

"Targan Electric Co. Pty Ltd was originally located at 15 Kerr St. Fitzroy. By November 1930 they had moved to 131 Brunswick Rd., Brunswick. They went into voluntary liquidation in 1935. In September 1935 a new company called Radiokraft Pty. Ltd trading under Air-Master Radio Pty Ltd was formed to manufacture radios under the Air-Master brand. They too went into liquidation in September 1936 and by 1937 the Air-Master brand had been taken over by Superheterodynes Pty Ltd."

Let us know the valve types in it and we may be able to determine the chassis.

From the photo we can see the valves are mostly octal types, a metal one and 2 small glass ones.

I'm guessing there's another valve out of sight.

Lastly there's an odd-looking rectifier (if that's what it is) on the right.

So, yes, a list of valve types would be handy.

Hi Mickey, nice set, but please don't plug it in and turn on yet!

Other members will probably give you a run down on how to procede safely.

Robbbert, the rectifier looks like a TV type 5AS4.

Robbbert, the rectifier looks like a TV type 5AS4.

I am thinking the same. I've had this valve come up in a few radios, including a Tasma 1001. In that case it worked but I do not like substitutes, even when they work and even when they are deemed acceptable, unless they are an exact replacement, such as 80 - 280 - 5Y3, etc.

For collectors, in most cases there will always be plenty of the right valve available.

Yes a 5AS4 will replace a 5Y3 but the filament current is 3 amps vs 2 for the 5Y3 and this might stress the mains transformer.

Yeah... it does look like a newer 5AS4 (older shape = https://vacuumtubesinc.com/index.php/vacuum-tubes/5u4g-5as4.html).

As you say, it's an extra 5 watts wasted for nothing. A 5Y3-type should be used.

Thank you guys for the grate info, advice and the warm welcome.

If anyone has a schematic I would love to have see it.

I am planning to restore it I love the sound and the look. I am also going to add a Bluetooth adaptor hidden in the back so I can play my records ect through it.

Has anyone done this before?

Hi Mickey,

If you don't want to alter your set by installing bluetooth components on it, you can get an AM transmitter. I got a Spitfire transmitter a few days ago and it is great. See here: http://www.6v6.co.uk/vcomp/pages/spitfire.htm

Hope this helps.

That is a great idea. Cheers Diego!

How did you get around the UK Plug ? Adaptor?

Mickey, when you place an order from Australia, they will include the Australian power plug with the unit.

It will then work out of the box.

Cheers,
Diego
