This type of Philips tube radio has always interested me, but they are quite expensive and rare. They also follow a slightly different design and build philosophy to the German radios I usually work on. All that just made me more determined to get one, and here it is. This is a mid-range set, and a good place to start. It is also almost exactly as old as me, so this gets personal.
I wanted to follow my usual procedure, but also needed to know if it worked at all. In this first video, I'll power it up to check, after taking the necessary precautions to avoid any mishaps.
Hope you enjoy it.

Hi Manuel, these are a nice radios, the better spec models had wooden end caps which look much better than the plastic. The thermal fuse Z1 on mine was missing and I manufactured a new one using Rose metal as Chris mentions below but I think it melts at about 95C to 98C, I still have quite a bit of Rose metal left if you need any (ordered from the Ukraine). I thought the string operated switch was odd, not enough contacts on the main switches I guess.

@electronicsoldandnew 2 жыл бұрын

I remember you rebuilding that switch. Mine is fine for now. When I grow up I want to get the B7X43A model, which is the top of the line for that era. They do come up for sale but are very expensive.

@chrisclark6192 2 жыл бұрын

Hi Manuel. That is a great radio and they sound really good when working correctly. The cut out link on the power transformer is actually a rose metal link and not normal solder. Rose metal melts at around 80 degrees. Years ago rose metal was used mainly by plumbers when forming bends in pipes. Again thoroughly enjoyed watching this. Cheers Chris.

I have the exact same radio. Those 2 tar capacitors are best replaced with 1000-1250V units if you are doing a proper restoration. They can experience very high voltage pulses if something happens with the speakers or the output valve. Otherwise, the mustard capacitors are all 100% fine, as they were perfected by the Philips by then (they are 2nd generation of the Philips poly film caps). I did have a problem with a shorted styroflex cap on my unit, this was caused because the cap was touching the insulation of the wire and it chemically reacted over the 55 years

@electronicsoldandnew 2 жыл бұрын

I agree with the caps rating, but these are 630V caps so should be OK. When I receive the 1kV caps I may well change them. Good to know about the mustard caps. I hope mine probe OK.👍

This was interesting. I have a BX7, can't provide the rest of the model ref as the radio is hard to get to at the moment! However, it is the bi-ampli model with reverbeo and stereo. The stereo confuses some people, because the radio section has FM, they expect to find stereo radio, not so. Not only was stereo FM not available when the radio was produced, the stereo part refers to playback of external sources, like tape and record decks, because, as bi-ampli suggests, it has a two channel amplifier section. So on radio it can deliver quite high sound levels. My example has been in the family from new, my father originally purchased it. He was a big hi-fi enthusiast so moved on to a proper audio system and gifted the Philips to my Grand mother. When she passed away my father repatriated it so to speak! At one time I worked for Philips service here in the UK and actually took it in one day for a service! One of the older service techs there had an original service manual for it and gifted that to me, he was really interested to see it as there never many of them in this country. I took the opportunity to replace all the valves, a few caps and, as the speakers were actually in stock at Philips in Croydon, I replaced them to! I also realigned it and cleaned it all up. The only thing that didn't work then, as now, is the electrofluroescent backlight panel behind the tuning scale. I would really like to find some way to bring that back to life. Otherwise it still works perfectly and is in extremely good condition, the piano finish on the wood even is still perfect. I almost sold it about 20 years ago but am so glad I didn't as the family history connection and my servicing experience with it are now cherished memories. They really are the pinnacle of the valve radio era.

Hi again, Manuel! I restored a radio just like this one some 3 years ago. It had the usual cleaning of switches, and all the tone switches were in bad condition, one broken, (had to glue the switch insulator). The tuning on FM is often called "variometer tuning" with the inductance. Also it had bad EZ80 and output. As we do not have national FM service any longer in Norway (alas) the owner wanted to hook up an external DAB adapter. Yes, that rear-mounted string-operated switch is a "typical Philips contraption" ;)

Fortunately we still have FM here, so these radios can get some use as it is. However, I will be adding a Bluetooth receiver to this to make it even more useful.

There are a lot of similarities in Czechoslovakian Tesla radios. Many of them have Philips heritage, as some of the Tesla factories were Philips before they were nationalized. Some Tesla radios also had the Wood's metal thermal fuse on the transformer. A common case was that the fuse blew for some reason (usually capacitors failing) and the owner just wrapped copper wire around the fuse, closing it shut for good. I have a parts chassis with such an improvement and - as expected - there are blobs of wax under the transformer.

Thank you for a really enjoyable video. I am currently attempting my first restoration of a German radio - a Nordmende Rigoletto 59. I have worked on a number of Philips radios, which are relatively common here in Australia, unlike the German ones. Your comparisons with the way German radios are built are very helpful. I have been using Carl’s capacitors since I started restoring radios about 2 years ago. I was amused to note that yours arrived in less time than it takes in Australia! I am enjoying your channel and I’ll watch the rest of this series through, probably tonight. Cheers

My pleasure Don. That Rigoletto is a great radio, and very similar to the grundigs that I’ve done on the channel. Actually, you’ll find that most of the german brands are incredibly similar in concept, layout and performance. They also tend to use the same tubes, so it helps. It’s actually serendipitous that you’re commenting here today, because only yesterday I mentioned you and your channel in a new video I working on. I hope you don’t mind - but I’ll understand if you don’t want me to. It’s a Philips 461A that I’ve started on, from 1937, and looks exactly like the 1082 you showed on your channel. I referred to your videos to help me open that thing up, because it’s a nightmare. The three parts to the chassis is a first for me, and I’d have taken ages just to work out how to remove the knobs. Mine is also a bit of a mess, but ironically it actually powered up and was receiving when I first tested it. We’ll see how that goes.

In the last two years there was also a Planoton B4A23A/01 and a B5X23A/74. I always thought these style radios to be the origin (at least here in Europe) of the modern (1970s and later) receiver - the radio itself sits near your record and tape player in a cabinet or shelf together with records or tapes in the most convenient location in your room and you have two full-size, three-way speakers positioned in the ideal listening position, at a location different from the radio itself. At least that's the way I would have used it.

Your video made me remember about an old tube radio waiting for the restauration on my shelf, so I went to quickly check on the basics. It's a yougoslavian radio, probably made similar to the german ones. There is not a lot of components under the chassis really and it surely looks quite different than this one. Restoring power section and the audio circuit is going to be pretty straightforward I guess, but I probably don't have the knowledge to repair the RF part if anything is wrong. And it seems not to have any FM. Opposed to your the tuner scale cord is torn. It was quite a luxury peace back then I guess: it has stereo output, inputs for both tape and phono and even switched jack for the external speakers. But under the chassis it's really messy. Rergarding the weird oblong 4-pin plug at the back - I have a Philips "pop" turntable from 1936 and it has the same connector. On my device it's between the tonearm and the preamp and so enabling to plug in an external sound source, eg. a tape recorder or a radio. To use the tonearm it is bridged with a sort of plastic jumper bracket. The only thing I miss in this plug is the ground pin.

Broken dialglass and no speakers, but the rest looks ok. The label on the chassis says "TYPE: B4X23A" just like yours, but then there's another label on the backplate that says "Philips B4X12A" It's a model where the front is plastic, not wood as yours has, and the top is covered in cloth or some fabric stuff.

Interesting. I've seen many Philips radios (I lived in the home town of Philips so they were everywhere when I was growing up) and this one is a bit odd. It pretends to be stereo but it's not. It's also no bi-ampli (two end tubes per channel, one for low frequencies, one for high), it doesn't have potentiometers for tone control, no adjustable MW antenna... But it does have the Philips record player input and a DIN connector. Weird! Definitely a cheaper model. I've seen Philips radios that look almost like this one with a built in record player, stereo amplifier, reverb springs and full tone controls. The speakers are on the side because Philips figured you would put them in a corner of the room and bounce the sound off the walls. I didn't know there was a system to the tube radio numbers of Philips, I did know they have a lot of hifi equipment where one of the digits is a hint about when it was built.
