In this hobby I always look for something different in the projects that I undertake, and this one is truly special. The B4X52AT from 1965 was one of the first transistor radios made by Philips, and is in the best condition of any radio that I have ever worked on. It was a gift from René from the Netherlands, and I truly hope I've done it justice.
Enjoy the video.

I have a bunch of those old Phillips capacitors, got them in a box of new-old stock caps from electronic goldmine out of Arizona here in the USA. While I have never needed any of them, testing shows they still are within specs via the M Tester. The rest of the caps that came in the box are new and all have tested great, most are good brand name; I love getting their surprise packages filled with all sorts of parts, it brings to mind a janitor sweeping up the floor of the warehouse and bagging all the parts that have landed on the floor during the days filling of orders or something. I have quite a supply of caps now and most of them cost less then a cent each, just that I need to sort them and store them. Thanks for the great video I love watching repairs and restorations.
👍
That's a really beautiful radio. I love that sixties look.
👍
That’s a lovely radio Manuel and a very nice gift. I’ve not seen one of those before. Great job on the filter caps. All the best Graham
Thanks Graham
Thanks for the video . Amazing radio receiver .
👍
Thanks for the video! 👍🏻 Amazing radio receiver.

Hi, Manuel. The 2 LW stations you are tuning from North Africa are Médi 1 (Morocco), on 171kHz and Radio Algérie, Chaîne 3 (Algeria), on 252 kHz. Regards
Thanks for the info. However, I seem to get RTE Ireland on 252kHz.
Correct. Both stations share the same frequency. But Radio Algeria having a much more powerful transmitter, you will be able to tune it during the day, as Médi 1, while RTE will only be heard during the night.
👍
beautiful it looks great.. grs.from Holland.
👍
I thought exactly the same thing about TVs. Some were in a dusty forgotten warehouse there's vintage color TVs still in the box unopened. Thank you for the how to video. Cheers
Pleasure
Hi Manuel. What a gem! I’ve never seen a radio of that age looking so good. Did you find the date stamp inside? Phillips have certainly lifted their game since the 1930’s in terms of serviceability. I could hardly believe it just slid out of the cabinet like that.
I think your decision to leave that circuit board alone was a wise one. They are so easily damaged.
Thanks for yet another interesting and entertaining video.
Rene told be it’s under the little packet with the spare fuse. I looked everywhere for it 😊
@@electronicsoldandnew they'll likely be date codes on some of the components, especially the speaker..
👍
Great video. A very nice, well designed radio.
👍
Permeability Tuning is the tern used for inductive vs. capacitive tuning.
Thanks. Always forget the terms when I’m filming 😊
That's a beauty!

Greetings:
FYI: A speaker with a second smaller one amidst the larger cone is either a coaxial speaker or a whizzer cone depending on the presence of a second voice coil/magnet assy. The whizzer is a small stiff cone mounted above the existing voice coil. Just helping where I can.
I thought I saw multiple dial lamps, but with the single lamp showing, the dial pointer is unseen in the video. The video shows a port for two dial lamps; but it is unclear whether one is for AM and one for FM or for better dial lighting overall.
Dave Tipton rolls the edge of the stuffed electrolytic between two pieces of wood mounted at 90 degrees held within vise jaws as he demonstrates in one video.
👍
Call the National Trust!
Maybe an alternative would have been to slice the big cap can in two where the retaining band goes round it. Easy enough to hide the cut then. I've found a pipe cutter handy for slicing capacitor cans open, although this can may have been a bit large. Nice result though, on an interesting set.
👍
Easy to disassemble Philips? Lucky man!
Truly lucky 😊
hmm, yeah, try repairing a 727A or even worse V5A/V7A 😉
Hi Manuel. That is a great looking radio. Possibly as close to new old stock as you are likely to find. Being a Philips, I was waiting for the awkward gremlins that is so common with the brand. Luckily you didn't encounter any. Superb stuff as usual. Cheers Chris
I guess the gremlins took a break 😊 for a change
@@electronicsoldandnew yep, i looked up the circuit and it's all germanium transistors, luckily not the AF11x types that suffer badly from tin whisker shorts but the later AF12x types which are much less afflicted, but still can happen, i've had the audio ones, AC128, etc. short to their metal case 😲
I am glad this is a one part video;)
👍
I guess my multiple series videos are not for everyone. I can understand it when someone wants to see from start to finish. That, however, is not how I normally do my projects 😊
I don’t think so. I understand people liking different types of videos, and can accept either choice 😊
@@electronicsoldandnew It's not about length of the video, it's multi part that I don't like. For multi-part videos, I wait until "final" episode and watch it completely.
I actually do that myself sometimes with some of the restorers that I watch. The reason I do it my way is because I don’t work on a project continuously - it’s my hobby and therefore sometimes has to be paused while life takes over. I therefore prefer to “report back” as I go along.
I think it's a wise decision to leave alone what isn't broke. If the capacitors fail later on down the line, you can always change them then. Those IF cores and that early PCB are so delicate, I don't blame you for leaving them alone. If it ain't broke, don't fix it is probably the best policy here. Great radio and great video to watch.
Thanks
I have one of the first philips portable record players from 1962...
👍
That's a great looking AM/FM mono set! Would it be worth it to put a second speaker in that nice ready-made spot for it? It won't be stereo but it might give it a bigger sound in mono. Or would that be too much for the radio's AF section?
Probably would mess up the output stage 😊
those blue philips type caps mostly seem to last well ,and you can still get ones that look pretty much identical, apart from smaller, under the name vishay
👍
Very interesting radio Mr. Caldera, I wonder if Philips never made any pocket transistor radio in the 1950s or early 60s, I do not think I've ever seen one I think, but it would surprise me considering it was such a large company.
Or do you mean it's their first full size (table model) transistorised radio?
And it has the typical octagonal speaker, which is completely tarnished of course, like they all are. But they do sound good!
I guess it’s actually one of the first table models, you’re right
yes they did do some 'pocket' sets, i have one, from the mid 60s .. as well as many 'larger' upright portables, from the late 50s
Like most manufacturers, Philips was making transistor radios in 1960 or perhaps even a few years earlier. But as with other manufacturers, Philips delayed converting the majority of their table radios to transistors until the mid 1960's. So, this is a relatively early transistorized table radio.
Grundig made some early transistor table radios that had battery operation such as the "Black Magic" sold in the US and in other countries under different names.
There is a more deluxe version of your radio called the "Pallas". It appears to have two speakers but is not stereo.
👍
For example Czechoslovak Tesla made its first table top transistor radio in 1962. Its in the same case like previous tube model. But it runs only on battery, there is not power supply for 220V.
👍
"Brilliant" Manuel your enthusiasm for the hobby and respect for the original design for these radios is infectious, fortunately the Phillips gremlins must've taken a long weekend when this radio left the factory. Your montage to Dave Tipton's skill is well-founded, I suggest however that as it's winter in North America and summer in Australia you see about visiting him. However a spy at your office says that you been delinquent and your desk is piled high with work. I miss your review of the schematic however, I agree your premise if it works leave it alone. Take the family out for Chinese we need more chopsticks.
I agree that Dave is probably having better weather than I. good idea 😊 my work does definitely suffer a little, but everyone I work with compensates for it 😊 I too miss the detailed tube restorations, and am looking forward to doing another one. Trying to juggle things on my desk 😊
@@electronicsoldandnew Sometimes I believe I get overenthusiastic about our banter and look for opening moves.
On the subject of Madeira whether Versus Queensland your climate is ideal (Preaching to the choir) average of 22.5°c low-16°, So Yes perhaps we should start a fund for Dave's vacation to Madeira. Alternatively might I suggest a joint channel teleconference rebroadcast on RUclips.
I’ve actually suggested the dual video to him, but Dave is shy 😊 he’s like me: took me ages to actually show my face, if you recall.
@@electronicsoldandnew Certainly I remember, but you're getting bolder all the time you even had your cat on camera.
True. And my daughter should appear at 20k subs 😊
In *1954, T.I.* released the first known 5-transistor radio called the *Regency TR-1*
👍
There was an earlier (1953) transistor radio which was never mass produced and was earphones only though.
Very nice radio we had one just like this , but a tube one and a little bit shorter .Unfortunately the shortwave broadcast almost dead in US , except few religious stations. Sometimes I receive Havana radio from Cuba .
👍
That Buzzing is from a TRIAC DImmer or LED lights. Not from a storm
Greetings. Can you tell us the model of the Philips radio?
It’s in the title. b4X52AT
Great radio from a company that was great in it's heyday. I noticed that this radio has no AFC on FM band. That is unusual but it works well non the less. Also, the term "Monday appliance" gets thoroughly debunked here.
True, no AFC. I guess on this particular Monday, everyone came to work under the influence of the New Year resolutions to do better, so it worked out well 😊
Germanium transistors might have to be swapped out for silicone transistors as germanium grow whiskers.
👍
6:30 Very often with this Type of DIN Speaker Connectors You can actually decide. You can plug it in in two Directions, one Direction will mute the internal Speaker, the other Direction - possibly - will _not_ mute the internal Speaker..I do not know why they actually did that, but they acually used the DIN Headphone Socket in this Way as well...
Good to know. Thanks
Sometimes the radio would connect to a speaker in a different room. My grandparents had a radio which used to be connected to a speaker - in the neighbors' house! - as they couldn't yet afford their own one in the 1950s.
So it makes sense to keep the internal speaker active in such a scenario, as opposed to when you just hook up a better speaker.
👍
TECHNICS Electrolytics might be the way to go.
FM sounds distorted, at the beginning.
Can you receive RTL on 234 kHz longwave? Sadly it will be switched off at the end of the year…
No, I haven’t come across it yet, unfortunately
Apenas lo ví desarmado, pensé que mal puesta la marquesina del dial que tapa la parte tweeter del parlante. Un punto débil de diseño.
👍
On a cap can that large, I wonder if you could just cut it in half where the bracer is and leave de top untouched.
I could have done that. Would have looked much better.
Maybe next time :) to be honest, no one will ve looking inside of it.
Its almost an OCD thing, we know what we do and we wish it was perfect :)
👍
RAFIQUE MASTOI SHJ UAE DG Khan great 🏝🇵🇰
Thank you.
A real time capsule
True 😊 I wish I was as well preserved as this one
Too much sun and that AIRPORT landing that took 10 years off my life . Still its a Beautiful Island will return , The radio is MAGIC , Thanks & take care
a@@electronicsoldandnew
We get use to the landing. Makes all other airports seem … boring 😊
@@electronicsoldandnew Me too!!!!
We must hold a convention Madeira … that would be fun. Nobody would want to leave 😊
In this digital age, there's something very satisfying, warm, and "organic" about good old fashioned analogue devices with physical "twiddly" control knobs! ... Digital is perhaps a little bit "sterile" and boring by comparison!
I too love the oldish knob controls …
nice beast!! thats nowhere near one of their first transistor radios, maybe their first mains 'tabletop' transistor radio? they did do some small bakelite cased battery ones similar to the 'philetta' valve sets, their first transistor radio was a battery portable in the late 50s.... i dont have one of that model but one thats maybe their second or third one ,(at least here in the UK)
as for finding a 'new old stock', i have a Defiant(UK co-op own brand) late 40s/early 50s small wood cased thing in its original box, looks pretty much A1, no use, or very little use
I believe you’re right. Must have been table-top model
And back to Philips... I see some sort of sadism in you :D
Yes, my wife said the same thing when she saw it. She still remembers the recent rants that I had about the other philips 😊
Appears to be a well made radio compared to today’s Chinese garbage that will fail in 2 months
👍
