I have got a "coffee Table" size radio with the brand name HALCO.
It's a nine valve unit, with RF amplifier (3 gang tuning capacitor) and........drum roll two 6V6s working in push-pull. 12 inch electro-dynamic speaker (electro magnet not PM)

Does anyone have any info on this manufacturer, all I can find out is that they were apparently made in a suburb called Nedlands, Perth - Western Australia

Nine valves.... That is huge in a table radio and so is the speaker by all accounts. This radio wouldn't be an easy one to carry. The AWA-branded speaker and STC control knobs is an unusual mix. Western Australia did have a few brands that catered only for that state due to the relative isolation of its population back in those days. It looks like Halco is one of them.

There doesn't appear to be much information on them in the usual haunts though I did find this console on Radio Museum which appears to use the same chassis as your set.

Interesting that VIC has top billing on the tuning dial.

Note the bayonet plug on the power cord.

The console referenced on Radiomuseum has two speakers. Would have cost a few quid in its day.

Wow thats a very nice find. I have not heard of this brand. I suggest you contact Steve he is a Radio Historian. I can't give you his email but he has some items listed in Wanted and for Sale.

Thanks for the replys....
Yes Brad, it weighs a ton.... Well about 20kg.
The cabinet is 1 inch thick ply wood (25mm)
Dimensions are 570mm high, 480 mm wide, 320mm deep.

After purchase I replaced all the paper caps, fitted an earthed mains cord, and powered up slowly via a variac,,,, the audio stages iworked, but no tuner,... After some hunting with a meter I found the B+ supply to the RF stages was down to about 50volts. I quickly found a 20k b+ feed resistor that had gone high, to about 100k. Replaced with a 22k new one and bingo, it burst into life.

I've got another unusual /rare one: a mantle radio branded " Stirling"... It to is apparently a West Australian (Perth) manufactured radio.
It measures 305mm wide, 350mm high, 225mm deep,
I'll send photos...

Cheers Dale

What about the electrolytics?

Buddy, contact Steve http://radiorevialparts.com/. He has all the radio history books and would probably be only too pleased to give you the info you need.

The electors; HT filters good. Surprisingly. So I left them in place.
Thanks for the info re getting hold of a circuit ....

After a bit of thought....Yes I did put a 10uf/400v cap across a 16μF filter cap. The original appeared fine, but it is 70 odd yrs old. I left the original in situ, using its tag to solder the new one to. I've never had an electro go short. Has anyone.? Only high ESR, or physical leakage of electrolyte, the original showed no sign of leakage.
it was done a few months ago so memory was a bit fuzzy.

I've never had an electro go short. Has anyone?

Not an Australian electro, but I recently has an English-made one short out. I turned the radio on, and noticed sparks starting to flash in the rectifier (6X5GT). The electro was a round metal one held in place with a band, and actually 2 capacitors in one can. So I cut the wire to the 6X5 and added a replacement. At switch on all seemed fine, and the radio worked, but soon a column of smoke started coming out of the filter resistor. The other cap in the can had also shorted.

Not a good idea to go lower in capacitance (and/or voltage).

The most spectacular electrolytic bang I've ever had was in a Trio oscilloscope. Quite a mess.

Dew, radio as this you need more than 400 volts with electros , ive got some in soon 600 volt more the better on the higher end in voltage. Best to have excess volts than not enough.

Chaps right ive had a Halco useing 7 valves and a 9 valve console,big chassis for a table set, not much info out there on Halco as they are hardly ever seen.

6X5 has not got a good reputation. I have seen exploded caps and recently had a 500V one fail before 500V. I know that as I had a voltmeter on B+ watching it. I have also avoided 450V ones not for voltage mainly for quality. eg failing after barely two years. I have not bought ecaps from that supplier since.

There should not be a big enough surge from a heater rectifier, for it to go much over 25V from the loaded B+ & not very many domestic radio sets go over 300V on "B" loaded.

80/5Y3 and non sleeved filament rectifiers & Silicon diodes are another story and for a 250VDC rail (loaded) I will not use a cap lower than 500V.

If an electrolytic has been sitting for over two years it often pays to reform before using, even that modern ones are claimed better than the old. The caps insulation is a layer of oxide, which disappears when the cap is out of use. It then can present as a short circuit.
