Why can't I stop watching this stuff? I have a 1949 Philips BX290U as an ornament sitting around. It hasn't produced anything for decades but humming and cracking sounds when turned on. Maybe I'll try recapping the old beast. Fun!
Shango, on those IF transformers, the deposited silver on either side of the mica wafer constitutes the capacitor, while the metal tabs are only contact points. The way I've approached this issue myself is by removing the wafer and testing it with a very sensitive digital capacitance meter in order to get an idea for the suitable replacement capacitance required, but this does usually require slight touchup of the transformers afterward since no replacement capacitor is exact. In lieu of not having a meter with enough sensitivity, I think your method of substituting the caps with variable trimmers is pretty ingenious.
You probably already know about this, but I recently came across the Electronic Goldmine in Arizona, where you can get high quality caps and such at a very decent price. Especially if you don't mind sorting out a mess of crap, get their gold surprise package, it is filled with top quality resistors and caps!
Hi mister Shango, my name is Angelo from holland. I just want to say that i am very pleased that i can learn so much of your videos! I also like the way you explain your videos and you speek. sometimes i really have to laugh about your super dry humor..so.. please go on with your wonderful videos! It gives me so much plesure in many ways! greets, Angelo from holland
you were talking about copyright strikes, I did a video not too long ago on working on a baseball themed pinball machine, I put a clip of Lou Gehrig doing his famous retirement speech in it, and they copyright striked me on that. A guy standing in the middle of a baseball stadium talking, from 82 years ago is somehow copyrighted.
Could you do a video on who to connect a sweep generator to a radio and then connect an oscilloscope, and configure the oscilloscope to use the sweep output, there are no videos on youtube on how to do this.
Greetings from Sun Valley (aka Burbank North), I have an idea that most 120vac series string (no input x'fmer) tube sets should work with an external 120vdc supply. I think that may be useful when you wish to rule out PS filter caps as a source of hum. Simply a line fed bridge rectifier and huge cap (isolation x'frmr optional).
That will cause excessive voltage. A 120 volt line rectified to DC would charge up to the peak voltage of about 170 volts. What Shango does have though as shown in a very recent video (to the time of this comment) is a 120 volt battery bank.
Nice save,on a cheaply built G.E.,but it sounds great i hate that kind of circuit board ,i have a G.E.i recapped,only caps were needed were the filter caps everything else disk i do love G.E. for that ,i dont have your skills.
I only get one radio station here in Mudgee! 93.1 Real FM & its shit. They play crap music & even the announcers are boring to listen too. I wish I could find someone in my area that is as good as you to repair my old vintage radio.

Radio sounds pretty darn good now. Fun to watch something come back to life.

Another great video... Them IF cap repairs are not for the faint of heart. Way to get her done Bravo
i guess it's quite off topic but do anybody know of a good website to watch new movies online?
@Merrick Gustavo Flixportal xD
@Grady Braylen thank you, I went there and it seems like they got a lot of movies there :D I appreciate it!
@Merrick Gustavo no problem xD
Holy crap there's alot of radio stations in L.A.

I would never have expected to hear a german song on one of your videos. Good job on this radio. Regards from Germany!
Que receptor bacana, pra início de conversa ele é valvulado, e os valvulados tem a melhor recepição e o melhor som! Rio RJ BRASIL

I have to agree, it's a good sounding set for a table radio.
Great video always look forward waching your videos
i love all the videos keep them coming shango066
That radio sounds really good Shango, Looks a real mares-nest inside though. J.
[ Pufferonies ] priceless ! Great fix.
Nice radio, sounds good.
Good stuff, as usual.
Where do you place your leads for sweeping? Awesome radio now that its alive! I enjoy table radios and vintage G.E.'s (mainly 60-mid 80's). ~Jack, VEG

Thanks for the useful information i do repair videos on mostly old radios lately. like you channelboh and i subscribed as well.
belly tripper i wasnt talking to you bud
Could you explain where the leads from the sweep generator and from the oscilloscope go on another video?
great movie shango
Great job. If I may ask...where did you get your training?
Why not replace the mica with something similar? What could work?

You really know your shit! Good work.
Hy, I'm buying some efficient speakers and I see a company named "Jensen" makes them. Do you have any opinion/comment about them?
I have the same radio but I don't know how to re-wire the dial cord because it has fallen off do you know how
5:01. Yep.. its called a crosley.
14:00 Was it really German female singer Nena with "99 Luftballons" ? On a American radio station? Nice. 😎
Yes. That was a big hit song here in the USA in the 80s from the one hit wonder!
@@jimw7ry She had much more hits in Germany, sung in German of course, because of "Neue deutsche Welle" this time. 😊

does anyone have a schematic for a magnavox 10t358r
is this a stereo set
6:13 sounded like thunderfoot for a second....
Those Jwco electrolytic capacitors are the nastiest, skankiest caps I have ever come across. I refuse to use them now
You could have puffaroni and cheese with those caps?. 😎
Now try to resurrect the parts set ! sure you can do it.
Nice save,on a cheaply built G.E.,but it sounds great i hate that kind of circuit board ,i have a G.E.i recapped,only caps were needed were the filter caps everything else disk i do love G.E. for that ,i dont have your skills.
“The can is crimped over the base” .. my patience is “baked” .. the caps are a bit “puffed” …
Could they have gotten the audio output tube and rectifier tube any closer together without using a compactron?😆
day 8368 b i'm going to mend and make this radio work god dammit!
Why people go through the time and or money to recap electrolytics and use junk new caps I will never understand.
y see a lot dry solder joints... lol....
Wow...compared to Zenith these look like junk.
Horrible factory wave soldering. I hated working on units with these kind of boards.

I know there are some people in Newcastle who could do that but its a bit of a drive , also how did you go with those fires the other day ?
Violence Jack those fires were scary that we had here back then. They came close to my parents place.
