I paid $90 for this beauty at Cash Converters, in Murray Bridge about one year ago, the turntable not working, but the radio works perfectly and has two shortwave stations. I found the turntable problem was due to the motor not turning, I simply pulled it apart and lubricated it and re-assembled it, and it worked but started running slow, then I attempted to fix the motor and accidentally pulled the wires out of the winding, completely destroying it. I was very fortunate, contacting a restorer who had a spare motor and gave it to me, now everything works wonderfully well and I bought a new stylus and cartridge and use it regularly to play my 78's and LP records, the sound is amazing, much better than these tinny digital things, even my transistor pioneer amp has been mothballed as the sound of this gem is just so much superior!!! It may be mono, not as loud as the 75watt per channel pioneer tranny amp, but the sound is just to full, warm and rich and the mid's and highs all in there and even though not loud the sound fills the house. Quite a gem, not sure exactly when it was made but I'm guessing 1957. It was 4 speed, however the replacement motor I fitted is only three speed, (minus 16 rpm). The record changer only works for the 12" records, the 10" 78's for some reason it drops the stylus where it should for a 12", however I'm not keen on the Idea of stacking 78;s in any case being much more brittle and also rare, but for vinyl albums it can stack 10 albums and play for hours!

What you have there is a 1959 Philips model 204A.

http://www.kevinchant.com/uploads/7/1/0/8/7108231/204a.pdf

This unit has high impedance loud speakers which dispenses the need for an output transformer. A pair a 6CW5 output valves are arranged in a single-ended push-pull circuit.

The Philips "HI-Z" series were more common in New Zealand. I think this is the only Australian Philips model that uses this type of output setup.

That's a very nice setup. Just pray that nothing goes wrong as there are some uncommon parts in that radio.

What is the shape of the tuning indication, that can be seen through the little window on the left? I have never seen a 6BR5 indicator.

Wow, thank you Monochrome, that is more information than I ever dreamed of! I'm a little dismayed that there are paper capacitors still in there I'd hoped it to be at least too modern for them, common consensus now it that these are bad news, although when I was at high school back in 1980, our physics professor showed us how these could be made using tinfoil, grease proof paper and dipped in hot wax, in order to replace them, although lots of trial and error involved in getting values correct, way too tedious really...
Just a shame, I had hoped this great soundpiece would just keep going forever, however it looks like I will need to replace these at least to guarantee that, in any case much better to know than not to, and especially to have a list of components to get in order, before attempting such, so really very thankful as I would have been non the wiser. Recently the dial cord broke, so I will have to pull the chassis out soon as I have ordered some new cord as although I have it tuned to my favourite station, I miss the shortwave at night! The tuning indicator is shield shaped exactly like the Philips logo, with a cylindrical bar graph like element with a green glow which rises and falls when tuning. That's amazing 800 ohm speakers in series!!! One is boxed up in it's own little box and one mounted as they usually are.. Well Phillips were on to something with this circuit as the sound is truly wonderful, it does go up very loud and starts to distort if turned right up, but I never need to operate it loud as the sound is so full and balanced, I had always thought music had to be loud and stereo to sound good, but this baby proves that entirely wrong, it's honestly a work of electronic genius, best music reproduction I have ever heard and it's mono!
