Jordan pier you are good at restoring vintage radios 📻 and alignment of vintage radios and vintage streos 🎉🎉🎉🎉🎉🎉

Jordan pier your vintage AM FM state portable radio from the 1960s is awesome 👌 👏 👍

Great job. Good to see these things being saved from the junk pile - and a suprisingly beefy output stage !

Favorite line "There's not a whole lot to these things, they're nice and simple. Now let's see, I gotta remember where all this stuff went"

I am glad there are people like you that restore old radios and other electronics. I would be doing the same thing if I had the knowledge and equipment. I am learning some, but not yet been able to practice on anything.

Find old books on how to service old radios. they were popular in book stores in the 90s. find old books on vacuum tube and transistor theory. learn how to solder - well. Learn to use a DMM well. Buy dead machines, learn by doing and try to get one working. Start with All American 5 tube radios. Work your way up.

Saw your comment on learning to fix transistor radios..I can send you some repair books.

Hello, I really enjoy you vids doing transistor radios. I can only hope that you choose to do more in the future. Tanks.

Look extremely close to my little JULIETTE FPR-1250, but the 9-volt battery clip goes to a holder for 4 “AA” batteries. The front styling is just a little different, but purely cosmetic. 📻🙂

Jordan pier your utube videos are awesome 🎉🎉🎉🎉🎉🎉

Old germanium transistors have lower voltage drop fully opened than equally specified and equally old silicone ones and germaniums also required less static bias (same current but over less bias voltage from equal supply) thus less static current consumption, so to squeeze out more power and convert less of it into heat, especially in battery powered equipment it was a common practice to use them in low power output stages. Soviets used to do this in portable radios even in the 80s.

The sticker on the back said 6V not 9 volts. I suspect it uses one of those larger 6v batteries with the 9v style clip connector

Nope, not a bigger 6 volt battery, a 4 cell battery holder that uses AA cells, and has a mating connector on it. BTW, the reason I'm saying AA cells, is the label said 4 x UM3: UM3 is the same as AA.. UM-1: D UM-2: C UM-3: AA UM-4: AAA

I Had An Old Philco Radio I Bought At A Garage Sale & It Had Very Low Volume. I Would've Fixed It If I Had The Equipment. At ThatTime I Was Only A Teenager. & I Didnt Have A digital Vom Meter Cause All They Sold Was The Analog Vom Meters. & That's Why My Hischool Said I Couldn't See Good Enough To Do Electronics Work.

I call those "ball game radios" because years ago people would bring small transistor radios to the game to listen to the play by play as they watched live.

Great vid, thanks! On the battery, it was pretty clean. There was a lot more noise due to the AC P/S.

You can also make a battery door out of printed circuit board which has the advantage of being able to solder clips to it. Yay! Shake-o-Cam and 1khz!

Great job. I wish I could do this stuff.

Has "ALCO" on the print side of the board, which was manufactured by Alconic International Ltd, Hong Kong. As for when it was made, can see a date code of "2G" on the Hitachi transistors, which is July 1972. i've seen Japanese 2SB germanium transistors used in Hong Kong made radios from as late as 1977.

@@JordanPier The 70s AM/FM/SW radio with the germanium transistors I've got, Is a Harrier Super Marine, plus I've got the original sales receipt dated for June 1977. Looking at my radio most of the transistors appear to be Philips plastic TO92 silicon devices, dated December 1976. Except for the outputs and those are Matsushita 2SB178 metal can germanium devices, with heatsink tabs attached to them. However on the rear there's a British registered design number, along with "(C) Copyright 1974". So it had probably been in production for a few years, using the same parts. The radio was made by MTL Electronics Corp, Hong Kong. I also have a made in Japan, Monatone brand shoebox type mono cassette recorder, was originally purchased new for Christmas 1974, and that is all Sanyo germanium transistors.

@@JordanPier I was thinking at the time, many manufacturers had a 'stockpile' of germanium transistors used in the audio stages, but given that you mentioned the Hitachi made plastic case transistors in the RF stages are not the most reliable, there must have been a prolonged transition from solely germanium to solely silicon, and to that, the use of an IC in the audio stages is another manufacturing dimension...

yes sending the components I saw that it was a post from the years 1974/1975 because in 1960 the components were more expensive

I wonder if that little gem was one of those no name radios sold at Woolworth?

Missing battery tray for four AA cells and battery cover. Tray connected to radio using a 9 Volt connector. A 9 Volt battery just makes it louder. Didn't Federal make a mini toilet radio ? I remember one that if you lift the lid up the speaker was in the bowl.

Another great video my man!!

Well that was ill, now it works really well :-D "Capacitors fix everything" lol i had to laugh. I'm thinking about a parallel universe that replaces good caps for halfbaked ones, and the good ones go back to a shop for advanced wearing out lol. Oh the shop gives you money for supplying old worn out caps to put in peoples radios. Yes i am silly.

Excellent

Jordan pier iam going to san Diego CALIFORNIA in October 2023 19-23 for five days with my cousin and his wife we are flying there 😊😊😊

This appears to be a post-CONELRAD receiver. It was probably one of the earliest ones to come off the assembly line that didn't have those little triangles at 640-1240 kHz.

Enjoyed your video. I'd love to have a capacitor wizard but the prices have scared me away so far.

Great Radio 📻

When it comes to car stereos like my factory 56002467(1991) Jeep Cherokee AM/FM Cassette Player, what is the cause of either the left or right channel going out and on a 56009004(1992) the volume knob is maxed out but needs just a little bit more volume? I`ve got cassette players also on some 56003021&3019(88-90) that won`t draw the tape in and seat it down into position but you can hear the motor running. You have to push the tape in and then you have to pull the tape out with needle nose pliers. On one player you have a high squeal thru the speakers but no AM/FM reception.

I have an fm radio that only picks up strong fm signals. Traced it to a few points on the board after the antenna that if i put a jumper clip on those points i get more stations. I can see a transistor on the board near the tuner but could it be bad?

That and vintage electronics would probably fare better with an EMP attack the silicon IC driven conglomerations..

Not really worth fixing but still interesting. During this era, they put phony wood on almost every consumer product. This was likely one of those radios sold at a discount store or perhaps as a "special purchase" on sale item. Because of the variety of component makes, I suspect this radio was not manufactured by a major manufacturer.

7:47 Question: Is this antenna lead for FM telescopic antenna or for AM ? Great troubleshooting video with lots of explanations.

Dear sir I have a radio for service which is not receiving anything. It's a 3 band radio I have removed the sliding switch and opened it carefully and cleaned everything in it and also checked the resistors, if coils and transistors which are all good. The Hunts mold-seal .0047mfd capacitors were used for bypass and many polystyrene caps in IF and mixer stages. These capacitors becoming hard to test and should I replace the whole capacitors in the circuit or not. Please suggest sir.

Remote troubleshooting a problem like this is nearly impossible

A bit of 'fiddling' gets good reception, sufficient for a copyright strike..! A good result with a few inexpensive components..

Why do we fix these things? Because it is nice to see one's hands are not shaking while soldering and one's vision stays in focus, as is often compromised with faulty robots, when control logic and original servos are no longer correctly working but they are still trying to solder new components in.🤖 Please, be not just a hobbyist, make an effort, and do try thinking like a correctly lubed and tuned machine.👾

You miss a good oportunity to use the signal tracer!!!!

You're turning the dial on the radio touching something in the radio. Maybe moving the coil of a wire. Maybe turning the pot, maybe maybe maybe. But I have no clue or what you're doing because you're showing me something on the generator, and if I can't see what you're doing on the radio, can adjusting something. Then I learned nothing.
