Grundig 3160 tube radio restoration, part 7. Finishing up, and final testing.

Getting the cabinet done took a lot more work than I expected, but now it's done. All the individual elements were properly cleaned, and everything put back together.
Time for a reception test.

Love these Grundig radios. Great to see the love and attention this old girl deserves.

[@alfredneumann4692]

It is an old Radio. And no one knows, which messages were told to us through it in the many many years. So it is no problem, if one can see the age. You have made a very good work.

[@electronicsoldandnew]

I sometimes imagine a family sitting around this radio hearing news of the outside world. I was born in 1963, so that era was over as we had radios all over the place, but in the 50s, these things were as important as a family car. They fascinate me.

[@kennethiman2691]

From a potential junker to a daily driver! That's what the hobby is about in my opinion.

[@electronicsoldandnew]

I agree. Lots of satisfaction when it’s done.

[@paulbennell3313]

Considering how you did it, the veneer repair worked out a treat. Now it doesn't have a massive chunk missing out of it and it's not embarassingly scruffy, in fact it looks very tidy. Ok, maybe it's not how you'd normally do it but given the circumstances I think you did an excellent job. I listened to the reception test with my Sennheiser headphones. Now I know I won't hear the exact sound produced by the radio via your microphone and mangled by KZbin's audio compression etc. but I can get a relative idea of it and it seems well up to expected standard. The treble seems exceptionally good, we can consider the elecrostatic tweeters to be healthy. As a Bluetooth speaker the sound quality must be equal to or better than the majority of equivalent modern items with the addition of one important but oft-forgotten characteristic: Pride of ownership. Someone owning an item such as this radio doesn't merely require a disposeable appliance that does a job. They want style and quality, the sort of quality that would likely cost four figures if such equipment was made today. I'm finding myself wanting something similar to this radio more and more. However, I still think any electronic restoration would have to be carried out by someone more experienced than I. I know a bit about valve equipment although my comfort zone is in solid-state and as the saying goes, "A little knowledge is a dangerous thing"...

[@electronicsoldandnew]

I agree with you as regards the pride of ownership, sorely lacking these days. As regards your journey, all I can suggest is get started on a really cheap set, so it won’t hurt if something burns up. I assure you the next time will be better 😊

[@davidward9935]

This radio sounds wonderful. The cabinet is beautiful. I, like you, come from the era of hybrid tube-solid state equipment. When I was studying Radio and Television repair in high school, I learned both “technologies”. I love the old radio warmth and glow. I also believe that if everything should indicate it’s era. Beautiful restoration.

[@electronicsoldandnew]

Thank you.

[@jginsc]

I wish I could get my hands on a comparable radio at a reasonable price but I can see why the values are pretty high, especially for one that's been restored. Maybe I'll get lucky some day. Great series. I watch them although I can't claim to understand a lot of the technicalities. I'm just glad there are people who want to keep these old radios up and running. God only knows how many have ended up in landfills.

[@electronicsoldandnew]

Too many, unfortunately.

[@petersvan7880]

What a great restoration, thank you for showing!

[@electronicsoldandnew]

my pleasure

[@__Dude_]

It's absolutely stunning what you did here! The radio was crap when you showed it in the first episode -- I woldn't have given it a second thought. But now it is a marvel. All that corrosion is gone, you repaired a clutch and what else. Maybe, just maybe, a little polishing. But like some other comments say, this radio is old. It is not supposed to look brand new!

[@electronicsoldandnew]

Thanks for that. I sometimes forget what was achieved, and ponder only what I failed to do.

[@stevewithers6766]

Yet again great work..

[@migsvensurfing6310]

I would be very happy with the result. Great work. Personally when I restore radios and other vintage stuff I never go for getting it to look brand new, it needs some patina so I think this one is perfect.

[@preiter20]

Beautiful restoration Manuel! Enjoy all of your videos.

[@electronicsoldandnew]

Thanks Paul

[@Wenlocktvdx]

Seeing it so well restored made my Easter.

[@electronicsoldandnew]

Have a safe one.

[@danielsaturnino5715]

Brilliant work for the current amount of resources ! I hope you are all doing well.

[@electronicsoldandnew]

One has to make do with what is available. We are well here. Hope all is fine with you too.

[@electronicsoldandnew]

Thank you

[@paulbache3940]

looks very nice, and I suspect the sound is better than average (hard to tell via utube)

[@electronicsoldandnew]

It’s very good.

[@tubeDude48]

Excellent job!! I would have made a DIN to RCA adapter.

[@mattmarion6442]

Beautiful work. Do you happen to know the type of bulbs needed for the dial illumination?

[@electronicsoldandnew]

Not at the moment, I’m afraid.

[@mattmarion6442]

@@electronicsoldandnew I just installed #40 bulbs, and they seem to be working fine. They're spec'd at 6.3V 0.15A, which is a higher current draw than the original 7V 0.1A but not excessively so. FWIW.

[@electronicsoldandnew]

👍

[@alastairchestnutt6416]

Very impressive AM reception. Sounds very pleasant on FM and bluetooth. Do the electrostatic tweeters make a significant difference?

[@electronicsoldandnew]

They make quite a bit of difference. Makes the sound complete.

[@retro_tech]

Great job (as usual)! Can you elaborate a bit on your "usual bath of shaving foam"? I'm restoring a 5195 (which has exactly the same grill cloth) but I can't manage to get it clean. I tried a bit of shaving foam on a corner but it only seems to make the fabric dull and fluffy.

[@electronicsoldandnew]

I wet the cloth with shower, then spread the shaving foam on it liberally. Leave for about 10 minutes and Rinse off with shower. It works pretty well most of the time.

[@retro_tech]

@@electronicsoldandnew Thanks! I'll give it a try.

[@sincerelyyours7538]

Looks and sounds great to me! Can you hear how well the electrostatic tweeters are working? Are they any better at conveying "spacial awareness" to the sound than, say, normal dynamic 4-ohm side-mounted speakers? I have a Grundig Type 2030W/3D awaiting a refit that has the latter speakers. It was supposed to have a "3D" sound filling quality that single-speakered radios didn't have. I'm curious to know whether Grundig radios with side-mounted electrostatic tweeters were better in that regard.

[@electronicsoldandnew]

I can hear the high end quite significantly from the electrostatic speakers on the sides. However, I’ve heard SABAs and telefunkens that used normal smaller speakers on the sides and the effect was the same. I’m not sure the electrostatics are that much better, if at all. They do add a “volume” aspect to the sound, making it “bigger” but I believe the wooden cabinet itself is mostly responsible for that.

[@Martin-io4wc]

Manual quick question. Who is the manufacturer and model number of you [red] multimeter? I like the feature of seeing ripple voltage on a dc measurement.

[@electronicsoldandnew]

It’s a Brymen. I have two. The little one is the model BM235, and the big one is the model BM869s. For dual readings (DC and AC), I use the big guy.

[@lyntonprescott3412]

Radio China coming in strong on SW!

China has good SW stations. I can listen Radio China very clear from here (Chile) Cheers!

Caldeira, Tipton, Carlson, Terry, George, Brad and Segeborn! I'm in for a valve/tube-powered easter!

[@electronicsoldandnew]

I always find it strange when someone lists me in the same sentence as Mr Carlson. I’m honoured. Have a great and safe Easter.

[@jerkerfridh8189]

Well, the great Canadian wizard plays an equally important role as do all the others mentioned. From various levels of skil and equipment you're all doing your best to teach, explore, explain and entertain, each with his own personal twist. Safe Easter!

Add Blueglow Electronics and xraytonyb to the list and all is well :-)

[@Martin-io4wc]

Thanks Manual. I will check out the multi-meters. Another item of interest. The LF beacon you hear at your location is aero navigation beacon 'PST' which operates with 400 watts of RF power on 338khz located at the Porto Santo Airport. See: www.google.com/maps/place/33%C2%B004'07.0%22N+16%C2%B021'30.0%22W/@33.068329,-16.3586109,497m/data=!3m1!1e3!4m5!3m4!1s0x0:0x0!8m2!3d33.0686111!4d-16.3583333 During the winter in the northern hemisphere it may be possible to monitor that beacon here in the USA near Chicago. If I log it I will let you know. Martin

[@electronicsoldandnew]

I know about the beacon, but had no idea you could pick it up from there. Do let me know if you do.

[@davidbrooks9073]

How did you go about fixing the electrostatic speakers please?

[@electronicsoldandnew]

I didn’t need to. I fitted them after cleaning, and could clearly hear the sound from them, so I did not open them up at all.

[@davidbrooks9073]

@@electronicsoldandnew that's a shame (not for you) was waiting for you to tear them apart and show how a pro would fix them...never mind, great videos tho cheers

Damn fine job! The unit deserves its Badge of Longevity. Thanks.
