Grundig 1070 tube radio restoration - Part 3. Audio preamp and power amp done and tested.
Grundig 1070 tube radio restoration log part 3. The audio stages are done, and its time to test them. The audio preamp and power amp now seem to be working just perfectly. Also a discrepancy in component values reares its ugly head.
Braun Atelier 3 Stereo (RC 9E) restoration log, part 4.
This one can get boring if you're not into the 'how it really works' vibe. The switching on this set is rather unusual, so I'll get into the detail using the schematic.

This is part 5 of the Graetz Musica 4R417 tube radio restoration. This series of videos logs the restoration of this magnificent piece of 1957/58 equipment, hopefully bringing it back up to a pristine condition, both functionally and visually.
The radio was purchased as completely defective, and I'll attempt to perform the restoration work in quite some detail.
Comments are gratefully welcomed.

In a recent video, I looked at a schematic for switching on the Bluetooth module in a tube radio, only when the pickup selector is activated. It used the fact that the magic eye tube was switched off when PU was on.
I then mentioned that a simpler option would be to simply use a micro-switch to switch on the power to the module, using some form of physical activation when the PU selector is pressed.
I decided to give it a try, and got lucky: A perfect fit with the first micro-switch I bought.
Enjoy and stay safe.

I use an ELV SUP3 Stereo FM test signal generator for aligning my tube radios, and have come across a couple of slight handicaps with this device: The output signal level is a little high for practical testing, so attenuation is needed. Another problem is the output impedance. The 75 Ohm output is fine for most modern sets, but not for the tube radios that expect around 300 Ohm impedance at the antenna input.
I decided to design and build a gadget that solves these two challenges. It is a stepped attenuator that can be switched up to 50dB of attenuation, as well as an impedance converter, from 75 to 300 Ohms.
The Gerber files will be on the PCBWay share section if you want to order boards for yourself.
Hope it proves helpful.

SABA tube radios represent, for me, the pinnacle of 50's radio engineering. This brand produced radios with all the 'bells and whistles' , and was, unquestionably, the leading brand of the day. The radios they sold were way advanced in comparison with its competitors, which was also reflected in their price. They were expensive, but certainly delivered in reception quality, audio response, and longevity.
This one is a Breisgau 8 Automatic, and came from a radiogram unit which must have been damaged and disposed of. It comes without speakers, but is otherwise the exact chassis that made up the Meersburg model. This means that it is fitted with automatic tuning, a feature that was undoubtedly revolutionary for the period.
I'm looking forward to doing this restoration as it provides numerous opportunities for learning. It won't be easy, but should definitely be gratifying, and fun.
Hope you enjoy the series.

Grundig was a pioneer in the field of transistorised world receivers in the 60's and 70's, having previously also been a market leader in the tube radio era. Many would defend that Grundig was indeed the leader in the transistor era, especially in the production of radios that have since gained iconic status.
The Satellit 6500 Professional was launched in the mid 80's as a progressive improvement in a series of really great receivers that gained a faithful market following, and is to this day something to behold.
I've got the 2000, the 2100 and the iconic 3400, and have always wanted one of these to complete the set. Prices are quite steep, but patience paid off and I got lucky here, so this is it - my own Grundig Satellit 650 Professional. It was sold as not working, which just makes the project a little more fun. I know, I'm a sucker for punishment.
Stick around. It'll be fun.

It's indeed rare that my wife actually comments on my radios, but this one beat them all. She wants it for herself! This is a unique opportunity to add a few more radio orders to the list, as it must be a weak moment she is experiencing :)
The FM dial extension needed doing and it was completed successfully.
The cabinet work was also tackled, and the final result was great.
Testing closes the chapter.
I hope you enjoyed it as much as I did.
