I opened up my dad's old Blaupunkt radio.
It has been idle, stored in one of my closets in our old house, for almost ten years and it was made in the early '60s.
Being a sixty year old piece of electronic gear is a big red flag. Shit ages, even though they are not in use.
Just pluggin it in can cause a great deal of damage if some of the capacitors have changed significantly. Or if they just dried out in the case of electrolytics, which would result in a dead short in the circuit.
BAD NEWS.
While I'm still a little gimpy with my left arm, I am planning to replace all the capacitors in the circuitry. It amounts to some bench work, but no real lifting or troubling movements. I can DO IT! It's all tubes, even the rectification. Way bigger than it might look. In fact, it is a little larger on the face than my 23" desktop monitor and about ten times as deep.
Here's a pic. I might have posted this old beasty before, but it would have been about three computers ago or so. Not sure.
Oh, BTW, these are not special in any way. They are not valuable, they were made in Germany by trainloads for the USA market and often sell on eBay now for fifty bucks in working order.
The only reason this is one is worth restoring and maybe a little special to me is that it belonged to my father.
We used to sit in our south Texas home on Saturday nights and listen The Grand Ole Opry from Nashville, Tennessee. AM transmission in those old days and it got a decent signal from over a thousand miles away, in the '60s.
Dad had a lot of radios. Radio electronics is what he did before his musical instrument repair business. This one was always best at picking up WSM, the station that broadcast the Grand Ole Opry. Sadly, Mom insisted that he get rid of all his old radios when they got super busy with the instrument business. He kept this one. It was by far the best and that includes about every brand you have ever heard of and a couple of other German brands you probably haven't heard of.
I wanted to keep the Grundig, too, but Mom wouldn't have it.
Anyway, I have his favorite old radio, now. It is up to me to help it last another two generations.
