Hello, just wanted to let you know that , finally after following you for years, (they just make me calm ) decided to get my own retro radio to get it work, im based in europe, got myself an old hungarian made Tera T 528 H, gonna recap it and write back, hopefully you could help me with the tuning etc. take care :)
Well you picked a good set there, schematics available on line and if you are new to old radio repair I will give you this very important tip. The glass dial is irreplaceable, do not clean with any chemical as the screen print is delicate and sometimes flaking. If possible take a detailed photograph on a white paper then replacement can be made from a colour print. Look up "David Tipton ". Enjoy you lovely set
@WOFFY-qc9te thank you so much, i will take care of that one, so far i did recap it, it works more or less lets say, i did check the voltages some of them are lower by 30 volts, some are higher by 10 , then i checked all the resistors, they are all within specs, i was thinking maybe the rectifier tube is weak but then the immediate out put of it is well within the range about 5 volts lower , its the other high voltage that is low the one that goes to all tubes, now im out of the ideas, also the cord broke ordered that one. also the weird thing i saw was that 1 on schematics there is a polarized capacitor where the negative is to the ground but on the set it was turned around ?! also found pictures of this cap and they were also turned around meaning the positive was connected to the ground the other weird thing i saw was that the heating element power supply was connected to the frame where on schematics it is not what would you suggest ? thank you in advance :)
@ Hello friend, thanks for the detailed description of your restoration, I underestimated your knowledge so forgive the tutorial on the dial as I thought you were a newbee to this dark art and I made that boo boo forty years ago. I am just starting a set so the first thing I do is take a photo as modern printing can replicate a replacement when unattended consequences occur. Without stepping on our esteemed hosts toes I will give you what I have found so far. First two model come up with that number, one is a trapezoidal shaped cabinet and the other a more traditional piano key affair which I think is your set with four speaker. Now I recall a chap on YT who is rather into Grundig and the Tarta which in my opinion are better. There are some quirky things with the tuning but I have not yet located the circuit diagram so cant be too much help at the moment. HT to the tube,s B* . I am making a guess that it is not hot chassis and has a transformer so first check the voltage is tapped correctly. The chassis will be used for a ground but in respect to the B+ of various voltages from the TX. So you say that the positive of a capacitor was to chassis in your set and another. It is not inconceivable that he chassis is positive in respect to the circuit. Now schematics are not always correct as Jim is frequently finding but some caution is needed. Ok I have just found a picture and the set I see has a TX to the right and 5 or 6 Valves (Tubes) two shielded, and two speaker and two tweeters and a magic eye in the centre no circuit as yet. So we have a transformer. I am not much help to you so far. Voltages, the rectifier voltages you are happy with and what is 5 volt between friends the 30 volts I assume is in the HT if so this is not a great discrepancy but it is anomaly which voltage test will chase down. You say the set works but you are not expressing much enthusiasm so room for improvement. I would check the polarity of the voltages you see on those caps both AC and DC. are they smoothing, filter capacitors or are they part of signal circuit. I suspect smoothing. OK just found this old circuit which shows pos to ground. (Valves are drawn old school.) I think this is correct drawing so proceed gently and do what Jim does limit the supply current and monitor the amps. Off to bed now. hope this has been of some help. past following into google. terta_t528-hg-k_am-fm_ac_receiver_sch.pdf

Alaskan here, (we are like Americas weird cousin). Our country is broken- and has been for decades. Those in charge care more about personal profit than anything else.....Its worse than that, in many ways. Trump may not be the ideal person to fix this, I dont agree with a lot he says...but he has many people behind him who love this country and want to fix it. We cant go on like this.....love your channel
I hear what you say but he should carry the whole country not just his right wing tribe that is suckled by his rhetoric which is no more than that found at a Wrestling match. The man is a grifter and he is using the system to keep himself out of jail, Musk is doing the sam but for subsidies for his cars and rockets both companies are finically very dodgy. He has cost lives and Ukraine is still at war because of his mischief.
Jim, Please don’t give up on us Americans, remember that about half of us voted against Trump. I do not blame Canada for our problems, they are mostly our own doing. My interactions with Canadians over the years has been great. Enjoy your videos- keep up the good work!
I presume this radio is being done for you and not a customer? Else why would you not take the time to open the IF can and replace that wire? Otherwise, good job on it all...I continue to learn a lot about radios from your videos.
I would replace that horrible anode wire by putting some heatshrink over it. And when are you going to teach those cats to recap and do a realignment. 😂
Jim - I've said it before - I love your videos and respect you as a person. I feel like you are a personal friend who's invited me into your home each day to watch your cats play and to watch you work on radios. I don't mind a little rant and raving about politics, but instead of just ranting about Trumps plan to implement 25% levies - please at least consider why he is claiming a need to do that. As I understand it, it is mostly because of your government allowing illegal aliens free passage through your country into ours. I don't know how much that happens, but apparently enough to get Trump's attention. If that is happening and Canada made no effort to stop it, then I think Trump's plan is a good one. He's not tossing goodwill into the trash just for the heck of it - there are reasons for it.
Smoke and mirrors illegal aliens !. It goes much deeper and instead of listening to him you may find the answer in the legitimate trade between Canada and the US and the resources of Canada that the US wants. And a crack at Greenland !. Whilst you looking into things check out the companies his family has interests in and what will be gained his deals. $2B stashed by son in law Sorry but you are being played. Canada is making products that the US needs but no longer make, like so many other products which proudly show made in US, the parts were made elsewhere because its cheaper and that is what the US people want and it cost jobs and revenue to the Fed net result is everyone but the rich loose. Bank debt in the US is ridiculous now at over a Trillion, that is like printing money, who pays that back to the banks. You do with interest to keep the rich going. Why would they want to change that system to make your life better. Like the story of the scorpion that was helped across the river by a frog, they get to the other side and the scorpion stings the frog. When asked by the frog "why ', the Scorpion replied, "it is in my nature" Trump is a grifter don't fall for his crap, laws will change and free speech will be lost. just like 1935. I am not having a crack at you, your comment shows me you are a smart concerned person, the truth is not in the mass media. Take care and don't borrow any money as the market is heading for a crash.
Thank you, Jim. I appreciate hearing a point of view from the Canadian side. More importantly, I appreciate hearing a point of view from someone whom I admire and respect. Not to worry. As a U.S. citizen, I can just about guarantee that the voting public down here will realize their mistake in fairly short order and will have "voters remorse". We'll fix it in four years. Don't give up on us in the mean time. Cheers! Michael in Champaign, Illinois, USA.
I agree. Remember, two years from now are the mid- terms, at which point party control of either body of Congress may change, as it usually does. Even if it doesn't, he'll be a lame duck.
Lets not forget many of we Americans have done our part to rid Trump of our government. We shall over come. Do not abandoned us because of rich, evil and uneducated people who put Trump in office.
Now that is Just DUMB open your EYES look to see what is going on there are plus to all of this all the Hate is not going to put the money Grubbers back in Office
Maybe YOU should take your caustic crap to some other UA-cam channel. We all behave like friends here and if you can't be respectful, go someplace else.
I cant believe how big those cat's are getting. Very pretty cat's.
Goodwill as long as it goes 1 way. Your tds is out of place here. How's your p.m. working for you?

Bert has some balls running up and taking over the bench. You might have to get used to that Jim.

Well spoken Mate. Maybe ranting isn't your style but you're good at it, you're right, and I for one could listen to it for hours.

the problem with fixing up old radios is there is almost nothing worth listening to on AM and increasingly nothing on short wave either.
Thank you for your message Jim! 🇨🇦

Apparently you've never tried to import goods into canada. And you just lost a viewer.
shut up maybe you shouild vote for a new prime minister

Je ne comprend pas la pertinence de ce genre de message
Voyons ! Get outta here.
;)
Canadians don't elect the Prime Minister.
