I’ve done numerous German sets like this one, and it really sounds like an alignment issue. You could do a simple alignment by feeding a 10.7MHz unmodulated carrier via a couple of turns of wire over the ecc85, and max the voltage level across the detector cap. Just tweak the cores prior to the last one (the extra sensitive bugger) for max negative voltage across the cap. I then just tweak the final one to null out the detector by ear for least distortion. If you find that this improves the sound then you can do the full alignment process as described in the service manual, which, I agree with you, can be a pain. Good luck. I really enjoy your work. PS: they actually suggest that you do an alignment after every change of the ecc85 because it does throw out the alignment by simply putting in a new tube, so the front end is really sensitive to everything you change there.

At this point I ask myself why I restore tube radios. 99% of "music" they receieve is trash anyways. Thats like being resurrected from the dead to become a Kardashian

Sounds like the discriminator needs a slight touch up' Like you mention if you go tweaking those cores, something may break loose. Maybe you can check for zero volts at the balance point, it may be dead on. I always remember your alignment video of a cheap transistor radio and how much the distortion was minimized when done. Keep at it, Dan, you can do it!

Coming along nicely Shango. That's a nice console too, fully featured yet compact.

Major takeaway from this video: today's radio sucks. My hat off to you though for working on what looks like a nightmare to repair. Learned a lot from this video.

The stereo effect is also enhanced a lot when the external speakers are plugged in. Grundig sets had similar layouts with bass speakers in the front next to each other, and tweeters at the sides of the cabinet + external mid range speakers, values were often 5 Ohms.

Loewe-Opta made one model of table radio, the Hellas 2841W, which had two front-firing woofers, two side mounted midrange speakers and a horn tweeter which radiated out both sides of the cabinet. It also had separate amplification for the woofers.

Shango you could do an alignment with a 6LB sledgehammer, this radio will then allow you to listen to people on the astra satellites, beaming down mind numbing spirit crushing gameshows whilst theyre stuffing junkfood in their mouths. Choose your future, choose Life.

I am genuinely intrigued by this set. These consoles are rather hard to find I’ve realized. I was offered a really large telefunken once but that offer never came to surface. Thanks for these great videos!!

You’d like to think the alignment won’t be off, and from what I hear about these German radios, it usually isn’t. But... The same person who packed the tube sockets with lithium grease, may have also started tweaking on the adjustment slugs, with no more equipment than the screwdriver with the broken tip in their hand.

I recently had a problem on a similar vintage Philips radio with the same tube lineup minus the separate output tubes. It picked out all the stations, but the volume was very low and the eye tube didn't move at all. Both on FM and AM. I found a problem by measuring the voltages on the IF tubes, g2 voltage on the one of the IF tube (EF85/6BY7) was only 2V. Caused by a shorted bypass polyester capacitor to ground. Replaced it, and now it picks up stations even without any antenna. Also the first time I saw that type of capacitor to short.

My Scott 320 tuner had very similar symptoms. It didn't have as weak sensitivity, but the audio was distorted like that. I found an old Scott tuner document that gave the basics on how to align it. Using that, going off the eye tube, and by ear, I was able to get the Scott pretty much dead on. What appeared to really clean up the distortion was what I believe to be the discriminator slug. I found when I was tuned to the strongest station, I was able to tweak it until I found the sweat spot and the audio was perfect. What I found interesting is with the discriminator dead centered on the scope, it appeared to be off when listening to it on a very strong station.

Way to go Shing it's coming back around that thing is awesome I don't care what you say I would you still adopt it

Shango you and I have the same mindset man I love your Humor man I swear I think we can be brothers

I'll try that again. The tuner socket looks suss and the other socket with all that white crap in it, needs to be cleaned or replaced. My mum has an old Kriesler radio gram (we live in Victoria Australia) AM only but with a decent antenna connected there was always a slight gap even on the strongest stations. It is a stereo 3 way unit with electrostatic tweeters and sounded great in its hey day. I never pegged the tuner seeing eye valve no matter what station you tuned in. It measured the strength and the closest I got was about 1 cm on the strongest channel. I wouldn't worry about that. Worry about the distortion and forget the seeing eye valve. Cheers from down under. Andrew.

I've seen those tubular ceramic capacitors in old Japanese dollar store radios. I didn't even touch them in the one I have; actually I only replaced one capacitor in the whole thing and that was a tiny paper capacitor across the second IF coil which I replaced with a poly one.

I have to buy one of these older radios, but with a better FM stage....the Zenith with the pre-War & post-War FM bands just looks cool to me...I saw one console with a wire recorder from 1947 on KZread, I'd want that just for the novelty, maybe get some of those wire spools, play around with it.

Life would be boring if no one was ever offended by anything.

9:43 What a reward for getting a 30+ year FM radio working lmao

shango You know how to maintain suspense!

This is probably a stretch but. have you tested the EM84 to make sure the eye actually closes? I came across a replacement one a few years back where the eye didn't close all the way at the proper voltage

25:05 I just came back to listen to that rap hahaha😆

34:47 There's the original Mumble Rap by Van Morrison (and if I remember correctly it features a transistor radio too).

To get rid of the distortion I'd do a full alignment, also I had to slightly detune the FM IF for a wider passband to get rid of the distortion on strong stations. If you have a sweep oscillator it's best done visually to get a flat passband. (or as you said, stagger tuned)

Shango do these old radios have something like, a "squelch" circuit ? I was wondering why there was no static between stations, and then you mentioned it ! I'm thinking back to the days we all had CB radios in our trucks..lol. They were fun ! Like having a cell phone party line.lol

You are so amazing man hahahahaha

Happy Holidays then!

If the limiter stages in the IF are not going into saturation and letting amplitude variations through to the detector, the ratio detector can interpret that as distortion. It is also possible that the IF alignment is off. The only real way to sort it out is with a signal generator and a distortion analyzer. All my knowledge of this stuff related to solid state equipment, but the same principles apply. I'm sure someone with more knowledge of vintage tube IF's will chime in and hopefully enlighten us all. I do agree though, it seems like a lack of gain issue to me as well.

Awesome video! When does your mumble rap album drop?

i struggle to get dab+ down where i live and kinda weak fm signals depends where its placed

I can't wait for part 3!!!, and Shango is right, to awaken after forty-plus years to crap that sounds worse than animal sacrifice, just isn't fair.

Shango, I am no expert I have a feeling that the problem is in the tuner maybe you should try impedance matching the antenna, try a bunny ear w/gain boost or something, what about that cap you changed in the tuner, could a 150-500pf trimmer be substituted? What do you think cause the failure in that cap? Maybe there are more bad ones in there. I hope you don't think I am trying to confuse you, but I am getting frustrated too, I can just imagine what you're feeling.

it had a turntable too. 10 grams tracking force but mum got it when I was 8 years old.

good job

at 16:25, why have a resistor or capacitor with a coil wrapped around it? I have seen this before in other valve radios, but never found out the reason for it. Thank you for any replies... Ian.

I don't know much about FM, but it sounds like there's some overloading going on. In an AM radio, if AVC/AGC isn't working right it will blast the detector---that's something that could be checked easily enough with voltage measurements

Another thing that seems to have gone away is the Stereo signal pilot light? Maybe not too soon to disappear, will be analog signal on the FM band?

@@Captionmarvelous The change in deemphasis should result in a bit more or less treble, most noticable in "s" sounds. Germany is also slowly working on pulling the plug on analog FM. We now got a service that's called "DAB+", it's digital an powered by the AACv2 Codec. One transponder could create a stream with up to 224kbps. The problem is: To save costs they cramp as many radio stations into that steam as possible, resulting in music station having to work with 48 kbps. The reception is awesome, but I can't listen to it for more than 10 minutes. Dynamic is lost, stereo separation suffers, and artifacts all over the place.

Distortion on weaker stations is exactly what you get when IF / detector alignment is messed up. I've got a '90s Sony that I had modified with 110 + 150 kHz ceramics years ago, and those appear to be badly mismatched, as since then FM sensitivity sucks and weak stations are distorted. Keep in mind that IF stages often tend to be amplifiers + limiters at the same time, which will widen their response as signal strength increases - it's a practical compromise to improve quieting with a limited number of stages, and obviously against textbook advice. Japanese tuners in particular tend to do that a lot. So a weak mixer tube would not cause the issue per se but make it more audible. I am under the impression that Nordmende was one of the worse German brands as far as parts quality goes... they were among the last to phase out paper capacitors for one thing.
