Braun T1000CD repair - part 2. Re-building the audio and supply board.
The disappointing discoveries in the first video left me rather down-heated, until I remembered that this is a hobby and a challenge, not a chore. The audio board needed complete re-building, and the result was encouraging. The detailed schematics were essential to get this baby up and running. progress is good, and so is the challenge.

In the last episode, I left off with the left chassis element completed, but with all the restoration of the right one to do. This proved less complicated than expected. Good.
However, the absence of Short Wave was a still problem. It took me quite a while to track the problem down, but it was finally done. Yay.
This one is coming along nicely, and I'm really enjoying it. The challenges of alignment still loom, but we'll get there in the end.
Enjoy.

I left off last time with quite a few tasks ahead of me to complete this project. What I didn't expect was for a mishap to occur to make the job even more challenging. Anyway, that was sorted and the needed alignment was done and tested.
The result was satisfactory, but this radio did not perform as well as some on the LW and MW bands. I believe it has to do with the imperfect connection of the mini-whip antenna to this set, and local reception using the ferrite antenna is not good where I live.
However, the job is done, and another treasure is indeed saved from the trash heap.
Enjoy the video.

In this, the second video in my 'Back to Basics' series, I tackle the power supply, starting at the absolute origin of all power, the mains inlet, through the switching, the transformer, and the selenium rectifier.
Some of my previously presented tricks are shown here, especially as regards testing the power transformer safely without connecting it to the mains, as well as replacing the selenium rectifier with silicon diodes.
I am taking it slow, as that is what many viewers have asked me to do, so I hope you get some useful insight from these videos.
Enjoy the series, and feel free to comment.

This tube little tube amp was made in two modules that inter-connect via two cables, allowing for installation in hi-fi consoles, where they were most seen. The Pye Mozart console is such an example.
This unit has a phono input, tape and radio inputs, and the power amp provides 9W of single-ended magic, using an EL34 power tube per channel.

Life is not all about restorations. Sometimes a break is needed, and I'm not immune to some serious beach relaxation. This Island is also completely Covid-free, which makes it absolutely ideal for a getaway.
The Island of Porto Santo is only a 2.5 hour ferry ride away from the Island of Madeira, and this year it seems like the entire population of Madeira has congregated here. The trip is easy and no Covid testing is required, so convenience and the stunning beauty of this place has served to make it the holiday destination of choice for my countrymen in these troubled times.
See you again soon.
