In case you haven't heard from me, feel free to just send me a quick email: inventordonations@gmail.com the same goes for basically anyone who lives inEurope (EU+UK) and hasen't gotten an envelope yet. Your stuff should have arrived by now. In that case, send an email. Don't answer here in the comments, because you don't want to post your personal address here. Cheers, Gerolf

I would like to publicly thank those who support you via Patreon so that we who are on fixed incomes and can't afford to do so can freeload on their generosity. That repurposing of the advertisements into a wall display is beautiful. I have no doubt that the advertisers who originally made them would have done something similar to display them in a booth at a trade show. Far better than relegating them to a landfill.

The picture project was not only inspired, but a great way to pay homage to retro tech.

I always enjoy your efforts at resurrecting old electric motors and pumps from the scrapyard. I also enjoy your background narratives. Keep up the interesting projects.

You should absolutely produce more repairathons in the future. I get lost in the electronics parts, but I still watch as if I understand everything. The lighted pictures are fantastic.

I owned that model of Amplifier in about 1983. It was around 8 years old when I purchased it. It was a fantastic amp. I was really surprised to see one again!

Extremely interesting as always, and as often happens in this small world of ours, the gentleman from the UK who worked for Mohawk Data Sciences. An acquaintance of mine, when I lived in North Carolina, was an Electronic Tech who worked for Mohawk. His territory ran from southern Virginia to South Carolina and he was “on the road” whenever a service call came in. This was from 1976 to 1982 and the Volvo 164 he drove had nearly 400,000 miles on it mostly from those “service calls”. Those early systems were foreunners of what we have today; who would have thought. Great Video !

Thank you for your comment. I assumed it was logarithmic, but did not find any information about that in the service manual / circuit diagram.

Eventually someone came along and said, that the letters are meaningless, and I was non-the-wiser. After installing the new logarithmic pot, it was pretty obvious though, that I had chosen the correct part as the volume controlls worked as intended.

The hollow drill bit is for cutting cross-grain plugs, to conceal screws or plug old holes. Measure the plug diameter and team it up with a drill bit that makes that hole. The process is called plug and pellet joinery.

That retro computer photo panel is one of the coolest things! I love it! Also, sad to see those spruce trees dying off. Spruce is fairly expensive here in the US (at least the high quality, instrument grade stuff), but I really love it for how rigid and light it is.

The hollow core bits are for making plugs, to fill holes, where screws were drilled,countersunk, and then covered. WITH the grain.

So it is actually a crime to take things from a junkyard or even from the garbage collection in a apartment building. The junkyard doesn't sell waste either as they do in Germany. So it's a tragedy going to the junkyard and see perfectly fine objects in the bins but not having the ability to take it with me. Keep up the good work!

The cylindrical cutter my father called a Bung cutter. My father used the bungs to hide a screw & hole . They hide better than a dowel because wood grain is going the same direction, and not the end grain from a dowel.

That is fascinating that the spruce is dying to the beetle. In the states we have the exact same problem affecting pines. Huge swaths of forest are lost every year, mostly where it was planted in monoculture, but in general is sweeping across the country.
