Grundig 2147 Restoration pt. 1. First look, and first listen. It's promising.

I have done numerous Grundig Tube Radio restorations in he past, and still I am drawn to the 'simplicity' and quality of these radios. This one is from the 60's, so quite a few years younger than the previous models I've done, but I really liked its looks. It was also (apparently) made in Portugal (?). The cabinet, while still in wood, is much more modern and clean than previous models. The faceplate is in acrylic, with a colour scheme that I find appealing and contemporary.
I embarked on this project with the hope that the result will match up to the modern looks, and expect to have some fun in the process.
I hope you join me for this project.
Enjoy.

Never seen this Grundig radio before, I will definitely be following you with this one. I was born in 1952 and start repairing all valve televisions while living in Gibraltar. My main place of employment was at Marconi Instruments Ltd, just north of London, where I stayed for 30 years, setting up and calibrating all types of test equipment. I'm now retired, but still love anything that is connected to radio.

[gaateman]

Great job with your explanations! I cut my teeth in the late 70's, early 80's on digital electronics - TTL logic and solid state. I'm just getting into tube/valve radio restoration for fun and I'm loving it. I look forward to your video explanations, I know I have a lot to learn and you seem knowledgeable and you have a good personality for this! Having worked in the technical support world for the past 42 years, it's rare to find a really good tech that can do good presentations!

[axxxxman]

Ok, I need to move to that island as it seems to have an unlimited supply of audio equipment. I am not crazy about radios, but this one really impresses me. I cannot believe how old it is because it looks so good.

[waynio]

That dial illumination lamp looks well used!

[__Dude_]

Not boring at all. Rather interesting!

[maangamandai]

Gorgeous! Reminds me of Blaupunkt Stockholm 2225.

[jameswortley]

Really enjoying your videos on old tube radio's. I have a Polish unitra that looks very much like the grundig.
Tube layout is the same and even the caps are the same with the strange wax that looks like they have been reworked.
Going to enjoy this.
Thanks for sharing your knowledge.

[EsotericArctos]

The knobs and front panel sort of remind me of some of the Braun stuff... It's a very stylish unit.
It is so clean and just nice looking. This will be an amazing restore.

[alexquant]

I liked the more dramatic Grundig badge on the coffee coloured model.

[tubeDude]

Your right, that's a real beauty! Looking forward to the progress you'll make! :)

One of these fell into my lap about three years ago. This will be my daughter's birthday present. Gotta see what's going on with that crazy clutch mechanism they used between am and fm.

[tomsheppard]

This is the set that drew me to your channel as I bought one bundled with an old Bush DAC90A for £20 the pair. The Bush needed a new output transformer, numerous Rs and Cs but ended up sounding well. The Grundig was going to be spare parts but if you can't see something broken without wanting to fix it... Restrung the FM drive, resoldered the ferrite rod and replaced seventeen capacitors. The FM sounded awful but the AM was fairly lively. A replacement EF89 from an old Philips Improved the AM a lot but there was no magic in the eye and scratchy weak FM. The EABC80 didn't seem to be charging up the detector circuit so I ordered up a new one and replaced the detector diodes with a pair of 1N34s by way of experimentation. The set came to life immediately with good, rich sound and a proper swing on the EM84. A little tweak on the detector transformer secondary added a little more and as the chassis warmed up, even the stiff tone control loosened up. Not the nicest set to work on in my opinion but the sound quality is spectacular. Thanks for the channel; keep up the good work.

[waynethompson]

This set is beautiful!!!
Of course, it needs the customary cleaning, recapping, etc. to be done to it, but it is a gem! I am looking forward to the finished product.
A FYI for you. Take a modern capacitor that you would use to replace a paper cap, and compare the diameter of the leads on the new ones, to what you have in the old radio. If the leads in the old radio are greater diameter, they are old caps. The newer ones have smaller diameter leads on them.

[phil.s]

Yes please thank you! I could really use some explanations and I like your videos, so double win!

[danielsaturnino]

New toy! *cough* project! :) it looks cool. Those cap tops are really weird indeed. Let the fun begin

[DerekHerbst]

You make a good point about the fact that there are very few sources of information in English about the German Radio models. These are engineered to a very advanced level for their time. When I saw inside the back I was, like you, amazed at how familiar it all was. The German "big six" is instantly recognisable. I'm looking forward to seeing how you handle the rewinding of the LW receiver coil.

I'm jazzed about this one. I bought a 2147 on Youtube 15 years ago for the same reason.Grundig makes great radios and it looks really cool. I t didn't and doesn't work. I am just beginning to repair/restore tube radios. This will be my 3rd and I am thankful to be able to follow you along. as I'm used to AA5 and 6's and older american tube radios. Just looking at the chassis made me put it back together and say maybe in the future. I've been hoping to find someone restoring one and wow what a great surprise to see one on y;our bench. I'll be hanging on every word as you go along. I have the dark brown front. Maybe there's hope for mine yet. Thanks, I really enjoy y;our channel

[kennethpetersson]

Looking forward to this restoration. Always so informative, interesting and inspiring. also a big congrats to 10.000 subscribers.

[audioreparaciones]

What a beautiful radio! It reminds me of Dieter Rams designs. So elegant! I hope you enjoy it

[greg]

Thank you for doing the work to produce these videos. I have been inspired to begin doing a few restorations; the first, a Grundig 2440u (about 90% complete), to be followed by a Saba Wildbad 7 now waiting on the shelf. Your methods and techniques continue to be very helpful to someone like myself who has very little experience in the field. Big (2) thumbs up!
