Shango, i'm living in Germany and i'm quite familiar with these German Radio-Sets, so I know the weakest points. But first I have to say: if you get this set running, you can expect a really good sound from it. Normally the Output-Transformers are very well build with 0,35mm (or 0,0138 inches, sorry we're metric) core-laminates, made of "Trafoblech IV", that's grain-oriented silicon-iron. Nothing very special today, but simply the best you could get in the 50's and 60's. The Speakers are "Isophon"-Speakers, a well known and highly regarded german Brand in this era -this wasn't crap. The Tweeters are HM10, but I can't say what type these Full-Ranges are. I see all the Paper-Caps in your Video and it shakes me a bit. Unluckily these are ERO 100's -or as we say here "Zahnpasta-Kondensatoren" ("Toothpaste-Caps") cause of the brittle-whitish moulding-compound. They are all leaky today and really have to go, especially in the output-stages and at all grids. The same for the smaller Electrolytics. The Speaker-Output connectors are the two on the right side on the back of the chassis. These are DIN-Type Speaker connectors, very common here in Germany from the late 50's until the early 80's. You have these with the 3 holes (the plug has only one thicker flat prong and one smaller round pin), so the plug could inserted in two directions, in one direction the internal Speaker were switched off, in the other not. So there is a Switch in these Sockets, and this switch has a very common problem, cause the contacts are silver plated -and now totally corroded after 5 Decades. So I would really say: figure these switches out and short the contacts so you get a proper connection between the Speakers and the Output-stages. If the ECC85 in the FM-Tunes is weak or toasted, maybe you can find a 6AQ8 -it's the only equivalent type. But I know these are not common in the US and hard to find. A last hint: check the B+ voltage. All these Sets used selenium-rectifiers in the power-supply and they often get weak and dropping the B+ voltage. Two types are common: the "Flachgleichrichter" made by Siemens (a flat, rectangular rectifier in a shiny aluminum-casing) or the "Rundfunk-Gleichrichter" made by AEG in a black metal-can like a Electrolytic. Hope this will help a bit. Fell free to ask if you would.

@@shango066 Sorry, I forgot something. You want to add a MPX-Decoder, so the whole FM has to work properly. This Set uses a EABC80-Tube, I know these are not common in the US, so you may not familiar with the circuitry around these tubes. The EABC80 has 4 (!) Systems integrated: one high mu triode (normally used for the first AF), one small Diode (normally used as AM-Detector) and two bigger Diodes with low Impedance for the FM-Discriminator. In this kind of Discriminator-Circuitry you'll find a Electrolytic, the common value for this C is around 5 Microfarads, normally for about 35V working voltage. This Capacitor is a critical Component, cause the AGC-Voltage for the IF-Amp in FM-Mode is sourced right there. If this Cap is leaky or dead, the whole IF-Amp will not work properly on FM. In most cases you'll find this Cap somewhere around the EABC80 and the last FM-Filter-Can on the PCB. The positive Lead of this Electrolytic is normally grounded. Good luck!

@@paulschuessler8477 Its the same as our T8 tube, 5T8, 6T8, 19T8 etc and its used in many radios and tvs for final fm stage. Zenith used it in almost all fm radios so its very common here. I am aware of the stabilizing capacitor too and will probably just change it.

Hey Paul, any thoughts on why the FM would be distorted? Anything over 50% deviation and the FM starts clipping
@albinklein76805 жыл бұрын
You can check the B+ Voltage for the FM tuner with an oscilloscope. I'm not 100% sure but I think the FM tuner gets its B+ through a contact in the bandswitch assembly. If this particular pair of contacts is dirty you get a very dirty supply voltage to the FM tuner, leading to a weird behaviour of the tuner circuit. If you measure it with a normal multimeter it looks fine but if you check it with the osmelloscope you see all kinds of crap. If you are very brave you can align the thing with the "original" procedure stated in the proper German manual. It takes about a week, tho... Btw: In my experience, the 6AK8/EABC80 Tubes literally never go bad. I had lots of Radios from the 50s on my bench with thousands of hours on them (burnt out dial bulbs, crusty tube sockets, shot bearings on the tuning knob) but the original EABC80 was fine. If the filament isn't burnt out, the tube is (almost everytime) fine. ALWAYS change the caps on the terminal strips on top of the output transformers!

It is not Normandy (French) but Norde (North) Mende (after Otto Herman Mende) and was a company founded by Otto's son in 1947 as Norddeutsche Mende-Rundfunk GmbH and shortened to NordMende. It became one of the major brands in the 50s and 60s in Germany. A friend's wife who moved here from England had one of these, maybe the exact model, if memory serves.

@@LakeNipissing Yep, they were still around in the 70s and still a big brand. They were known for wonderful radios when most other makers cheapened out. They started losing ground around then in the super-competitive TV field and, like our own brands RCA, GE and so on, ended up being swallowed by the French Thompson company. (Now Technicolor SA) An Irish outfit now uses the name for appliances and TVs but there's no connection to the original. Nowadays even the Japanese are swallowing other brands or selling them off to others. That comes from outsourcing production. Same thing that happened to our brands. Distinctions disappear and consumers become aware that they are not getting the actual name on the stuff but something from a no-name. Brand loyalty becomes impossible when even brands are not loyal to themselves.

Sorry for jason cruzing, but you definitely have to recap german radios of this era. I am german and those "Wima"-capacitors are nicknamed "Knallbonbons" (in english "firecrackers") for a reason. The yellow tar/wax capacitors are crap as well. The Styroflex(mylar) and the tubular ceramic ones are mil-spec and not to worry about. I use a nordmende parsifal tabletop radio (more or less the same as yours) as a daily driver in my kitchen. It has the original greencone alnico speakers in it and that thing REALLY shakes the house. Its insanely loud with those high efficiency speakers and the maxed out (310Volts) el84s. The only drawback is the old German FM band it tunes (88-100MHz).
@MrHBSoftware5 жыл бұрын
you are right, they are worse than paper caps....i have some Knallbonbons rated at a 1kv and if you feed them with 100vdc they let pass 20v, they basically turned into resistors

The repair estimate looks like it was for a Denon DRA-375RD One thing to prolong the life of these German radios, is to set the voltage selector to 145 instead of 120 or 110. The tubes aren't driven as hard. Usually the voltage selector on these is 110-120-145-220-240... not sure where in the world 145 VAC power supply would exist, but it serves a purpose as mentioned above.
@RODALCO20075 жыл бұрын
Italy had 160/270 Volts power supplies in remote areas in the 1950's. Obviously the voltages at those days were way lower hence the 145 Volts tap was allowed for.
@1995voyagerES5 жыл бұрын
If the 6,3 volts are like they should I would say leave it at 120/110 because usually the selenium rectifier is tired and doesnt let the voltage through that it should. Thats what I experienced with my old radios. For example I have a Kuba stereo console where only 210 volts are getting through instead of 265. We have 226V line voltage and the transformer is on the 220V setting.

Thanks for the information about the 160 Volt AC supply, Ray. I have wondered for ages where this "medium" voltage was used, and even searched online, and found nothing.

All the audio companies made stereo consoles in the late 50's, all you have to do is add the stereo! Isn't like buying a car with automatic transmission, and all you have to do is remove the clutch and add a torque converter and a bunch of pumps? I admit that I was intrigued enough to read the entire wiki article on "stereo" and it's quite fascinating. Sound engineers began in the late 1800's to make electrified audio more directional and stimulating, mostly pushed along by the movie companies and finally to consumers about 75 years later.

Funny fact: many of these radios would shut off B+ tot he FM section when not on FM. Another funny fact: those ECC85's did not like to be running with heaters on but plate voltage off. The cathodes would get "cathode interface resistance" and act like there was a built-in 2.2K resistor in the cathode lead. So one often finds those tubes completely dead, especially on radios out in the boondocks with no FM stations.

The output tubes share a cathode resistor so running only one tube would bias it way above maximum plate dissipation. These run at around maximum normally anyway, increasing the cathode resistors would increase the life of the output tubes. I'd replace them with two separate resistors and capacitors sinc these are two independent stereo channels rather than push pull where a shared resistor would have less drawbacks.

Hey Shango? That receipt is not for repairs on this console. It's for a Denon DRA-375rd receiver.

I'd personally watch the whole thing if it were a 5 hour epic, then again you gotta keep us in suspense (or suspenders?) :) it's a staple of traditional programming to leave the audience always wanting more. Love your "Google" guy at the end of the video, I like it when they play along. Oh, my Beovision 8802 is working now.

Cool RPM app you have there Shango. That white button on the TT senses the 10" record size. The lever near the tonearm support senses the 12" records. No trigger means 7" records.

It was called the Trio-Matic. It was introduced in the USA in 1951 by V-M (Voice of Music). In Europe, it was produced under license by Grundig, in Canada by Seebreeze, and in Argentina by Winco. These companies often put their client radio manufacturers' brands on the turntables.

It was a good solution to the record size detection problem for auto changers, but it was not foolproof. It didn't work well for mixed size record stacks. BSR's Magi-disk selector was fool proof. It used an index flag near the tone arm that each record passed as it dropped. full trigger was 12", half trigger 10", and no trigger for 7". Even in a mixed stack, it knew where to drop the needle.

@@dougbrowning82 Yes, BSR and Garrard could mix all 3 sizes, as could Collarro (Micromatic) if you put them in order. V-M must have gone on the assumption that 7" records would have large holes, so there was no need to intermix them, so the button could only tell if the first record larger than 7". Not perfect for the UK or AUS, where 45s had small holes. Still better than the dumbed-down changers of the 1970s; Garrards with only 4 speed-size settings were the worst.
