Philips MT4 Swingalong Transistor Radio New Year Restoration Part 2
Ahh great job mate… you can’t beat the sound of an old AM valve receiver must get mine in the bench and get them working
Thanks Champ. Yep, Am valve radios and radiograms are the best. They remind me of when I was a kid listening to a DJ playing all the hits and best of all, it was lo-fi lol
Nice restoration Frank, at least you had a schematic diagram for it.
Excellent job Frank, great interesting video to watch. Thank you for schematic too, must put more on my "Drive" for everyone ! Cheers
Thanks so much Baz :)
ps: Yes, the more schematics we share the easier it gets for everyone. Helping people is the best reward
Great resurrection Frank. This hobby requires detective work and sometimes luck. Look forward to your next video cheers
Definitely luck at times Chris, Thanks for watching :)
I always hate to see radios like this especially with wires hanging everywhere. I would never have even taken on a job like that so kudos to you Frank you did an amazing step by step job.
Larry, when I first saw it I thought no way, then after having a think I thought why not, I cant make it any worse lol. In the end it wasn't that hard esp with a bit of luck thrown in.
I think that you have done a fantastic job on this radio. Well done.
Thanks Terry, much appreciated :)
Well done Frank, a great resurrection 😁
Thanks again Mike :) Three years ago I would not have had a clue of what to do lol
Good Show
Thanks JE, much appreciated :)
You have gotten to be quite the sleuth when it comes to putting things right into a partially complete radio. You might be able to claim you can fix everything but stupid. My hats off to you Frank.
A compliment from you is a joy to read Steve and boosts my confidence, thanks so much 😃😃😃
Howdy there partner. Nice simple set of solutions to the solid state version of a three speed record player. Scrabble anyone?
Howdy Tex, three triple word scores for you lol
Nice little player. I remember these kind of players from when I had a repair shop aeons ago. They used an extra winding on the motor field winding as a transformer to power the amplifier. Ingenious
Nice fix and sounds good. Love your music choices 😁
Thanks Mike, Cowboy music is tops lol
Nice little player Frank, I must chase up some of those cartridges, need a couple very soon. Top Vid as always !🙂
Thanks so much Baz :)
What really surprises me Frank is how many people want their old radio repaired rather than go out and buy a new one. And its obvious most people in Australia do take very good care of their radios. My question is are new radios that expensive in Australia? That's great you got this one to work so well. My first major transistor radio was a Zenith 1000 oceanic that had broadcast and 5 SW positions. It was made in 1957 and I got that one to work with a minimum of work. ua-cam.com/video/YFk7Km6kh6U/v-deo.htmlsi=Nukp7rgPxkzE4EA7
I think nostalgia has a bit to do with it Larry in bringing back memories of listening to granddads or aunties' radio when you were a kid. Some people have definitely looked after their old radios while some just leave them in the shed for decades. I'll check out your video too. hope all is well with you :)
Thanks Frank, love the funky red circuit board 😁
The poms had a bit of flair back in the day Mike lol
Good Show
Thanks :)
Yeah Frank, we say shits and giggles here also but for some reason I cleaned it up a tad. I see that the American manufacturers aren’t the only ones raising their transistor count up for a selling point. That radio is only a 7-transistor radio because TX4 is a diode since the base and collector are wired together making it a diode. Thanks for sharing the video and the prints. The radio does sound nice and definitely a keeper!
I wonder where shits and giggle came from Ken lol? Yeah, it is a good little radio and definitely a keeper. I wouldn't mind another one in a different colour
Surprisingly it works like a champ! Recapping it will make it last forever. The engineering design was excellent. Didn't need the center tap supply.
It does work well. I've been listening to it all morning, so far no glitches
Why only 360p?
That is strange. Is YT getting cheap on the bandwidth?
I have been given a 150 C in a nice bakelite case. How did you get the knobs off ? Don't want to wreck them .
Hi, trying to remember but I think I just had the chassis only. If there's no grub screws holding the knobs on then they just pull off. Likely they're stuck fast to the shafts. One trick is to wrap twine/cord several turns around the base of the knob and start pulling. They can be difficult at times. I've also used a plastic lever designed for car trim removal. Hope this helps, and you have a great name for a song BTW :) www.amazon.com.au/Wetado-Upholstery-Fastener-Terminal-Blue-8PCS/dp/B08ZHZMMHR?th=1
Interesting and cheap radio Frank, 3 different style tube bases and no on/off switch, whatever the model is, this Aristone is a very poor-quality, low-grade radio but nevertheless it would be in order to repair. Thanks for sharing.
Thanks Frank, another great fix 😁
Thanks for watching Mike :)
Never seen one of these radios or that fancy red valve Frank. It certainly sounded good after the caps plus only 1 IF ! Would need a good antenna back in the day I'm assuming. Very interesting video !👍
Thanks Baz. Aristone were cheap and nasty as you can tell lol. Radio Museum says they were mainly sold by Myers but the company also opened a showroom in Elizabeth St. here in Melb. Yeah, those red loctal valves were common in Aristones and Stromberg also used them occasionally
Pretty nice job Frank. Always good to have a fairly easy one.
Thanks Larry, always a bonus when the easy ones come around :)
Never saw an aluminum encased Loktal tube before. The maroon colored jobby, an EF50/VR91 which were used quite a bit back then. Surprised after a tube pin and socket cleaning it works! New caps really fixed it. Too bad it must have an on/off switch on the line cord, one IF transformer , and find a long wire for an antenna. Real cheap design for sure Frank. Known as "city" radios.
I can't think of the owner's name ATM Steve, but he was renowned for cheap sets. He would buy excess cases from the manufacturers and fit his cheapo chassis in them. I don't see those loctals very often, but they were also used in a particular stomberg mantel as I recall
Thank you frank for a nice video. I discovered the pigtails on most modern caps and others are tin plated steel. I guess it’s a fraction cheaper but makes the wire difficult to bend. I have read reports on the uk vintage radio forum of these leads corroding. Ironic the inside of the cap will last for ever and the leads rust through!,
Thanks Robert. I've noticed the thickness of some leads are greater than other and yeah, they are hard to bend
its good to know the basics . thanks for the video frank.
Thank you Larry
Thanks Frank 😀
My pleasure Mike
Thanks for doing the segment on volume pots, it’ll be a big help.
Happy to help out as much as I can :)
I always thought the reason they are called pots is because at times they can drive you potty. Very enjoyable video.
lol, how true Terry
Good little vid on pot part replacing . More important is testing it to see if you were successful at doing it.
spot on as usual Steve :)
Great video for the newbies Frank.
I would never scrape the carbon off a pot.
@@kenf8563 Thanks Ken, I hope it helps some people. I agree on NOT scraping the carbon
That came up really well good job. Where did you get the repro dial from? I acquired one of these recently and it has been recapped and is working. The dial markings have flowed down thr glass with time not helped by someone trying to clean the rear of the glass.! . There is still rubber wire to replace. The HT is higher than the manual shows at 225 volts but that seems about right for a 6v6 These are a most impressive set and the sound is good lots of bass. They were expensive , according to radiomuseum 27 pounds in 1948. Also the converter valve doesn’t look like a ech35. At one point you did replace it with a red one. The ech35 has double the conversion gain of a 6j8 or 6k8. They are all pin compatible though.
I can't believe that radio left the factory with no on/off switch, perhaps whoever changed those 3 capacitors had to change the volume pot. For a seventy-year-old radio it's in pristine condition.
I see this a lot from past owners who tinkered with their sets Ken. Yes, it should have an on/off switch being from the early 50's. Prior to the war on/off switches were pretty much non existent in radios down here. At least it was looked after rather than sitting in a shed for decades
Thanks Frank, that radio is as old as me 😁
You're as young as you feel Mike :)
Another one bites the dust. Thumbs up from me. 👍
Thanks Terry :)
Nice one Frank. I haven't seen this model with that valve lineup. I reckon it was a Friday & use up what valves are left !😁
You're probably right Baz lol. Any idea why I got full volume when I switched off the variac?
@@exeterslab7781 no, doesn't make any sense at all. Might never do it again, until the customer gets it back, 😆
@@techobaz55 lol with my luck yes!
Good one Frank. Looks like a highly collectible toaster instead of a radio BTW.
It's probably worth more as a toaster Steve lol
@@exeterslab7781 Is it for sale? I have bread
The missing link
lol, I love it Thanks Paul
Thanks Frank, at least you found out that everything else was OK 😁
Mike, I had to laugh when I saw the problem, pity it took me so long lol
Looks like you had a case of a jumper wire gone AWOL, that’s what I call bridging the gap.
lol. Good one Ken
Some American radio have a jumper plate between two terminals to go from the loop antenna to a longwire but this is very odd otherwise. Follow the wires until they end!
You got that right Steve. It's something I just don't bother looking for. I will from now on lol
It's funny how the silliest of things can trip anyone up.
Yes and so annoying when you see the obvious lol
Any chance you could do a video on changing a volume control?
I certainly can
European tube gear is so weird.
I think that's the smallest tuner I've seen so far on your radios Frank; those permeability tuners can have their advantages, and the radio/MP3 sounds great. What, Trigger's not into commercials?
They are tiny for sure Ken and the MP3 on these sets always always sounds good. Maybe Trigger was out to stud that day lol
You oughta get hold of one of the late Tony Maher's B battery supplies. Very quiet and delivers the goods, runs on only 6 AA batteries.
I'll look him up for sure. Thanks
Nice fix and adaption, loved the hat. Thanks Frank 😁
Thanks Mike. Yes a cool hat, I want one lol
Roy Rogers brings a new meaning to the word recapping. I think you did a banger of a job with this one Frank. All puns intended. LOL
lol, thanks a heap Steve
I definatly want one of those hats Frank, can wear it in workshop to stop any intruders ! Good vid mate, I like those Philips radios but some have dodgy IF Cans, which I have found out. Cheers
I think we'll have to get in line for a hat like that Baz lol. I've not come across any bad IF cans on these or the Fleetwoods, I've been lucky I think
