When a tube has gas ... it's not good. Grundig 2140 restoration - part 2 #PCBWay#
Only $5 for 10 PCBs and every new member get $5 bonus. + Express 24 hour / 48 hour service on https://www.pcbway.com/ I started this restoration by following my usual method, but got a little side-tracked when I got too involved with the chassis cleaning using my airbrush compressor method. Even the DIY tube tester got in the action, and proved its worth. We're a long way from completion, but things are looking good. Enjoy.
In my hobby restoring tube radios, I have so far resisted getting a tube tester. I believe they are too bulky and expensive for my limited needs. I normally just keep a few (known working) tubes on hand, and swap one in if I suspect a tube has failed. I recently did some rudimentary testing on an EL41 power tube, and this led to the idea of creating a simple tube tester for the rather small range of tubes that I normally find in the radios I work on.
I received numerous requests from viewers interested in this project, so I decided to get started on it. The first step was to create the multiple power suppliers that the tester will need. My first attempt left me frustrated with its complexity.
This video shows the process of creating and testing this first attempt, and also portrays the reasons why I decided to go for an alternative solution.
Hope you enjoy the process.

Continuing with the alignment saga on this Saba Breisgau 8, we have to do the tuning motor section. This has two alignments, namely one for the AM and one for the FM signals. We're still on AM right now, so that's what gets tackled here.
Another alignment task is the RF alignment, to ensure good correspondence between what you tune to on the scale and what is actually being received. This required me to repair the broken dial glass, which came out 'OK'.... sort of.
Hope this video proves instructive and fun for you.
Enjoy.

The issues on this radio ended up being quite simple to solve. It's always easier when you can find references on the web and comments from others who have had the same problems!
The final result is quite amazing. I also managed to include some of the specific request made by the owner, like adding 'stereo' headphone output and an alternative DC supply.
Hope this serves to inspire you to get more of these beauties working again.
Enjoy the video.

Telefunken Opus 2004 tube radio restoration - Part 1.
A fabulous stereo tube radio from 1959. The speaker set promises some really good audio when it is done. As I intend to connect a bluetooth receiver to make this set more versatile, this aspect is very important.
It seems to have had some previous work done on it, but is not in bad shape at all.
The cabinet is in excellent condition which always makes my job more rewarding, as I really don't like cabinet restoration work.
But, will it power up and receive anything? Due diligence is called for before we power it up, so the journey begins.
