Today I learned that 3mm TIG rod is just a naked 200A slow-blow fuse 😅 But seriously thank you for all the pulling wrenches and moreso for the wisdom you share.
You made my day man. Plus, today is a public holiday. Estonian victory day marks the victory of Estonia and neighboring Latvia in the Battle of Cēsis against the Baltische Landeswehr on June 23, 1919. God bless you.

When you go to a "junk yard", I call it the opportunity yard. Think of all the things that can be made with all of this material. I'm kind'a like you. Growing up, I didn't have a lot of money to buy new stuff. So getting used stuff was the way do go. Getting used equipment and transforming it into something that I can use is the challenge. Good job by you in all of your projects. Just remember what Ben Franklin said, "Necessity is the mother of invention".
I find your videos more entertaining than most television programs these days, keep them coming, always things of interest and a good picture of how much waste we humans produce, so much stuff thrown away that still preforms works with a minimum of repair and effort so much unnecessary waste it is sad really and what could be cooler than a spot welder[built by] named after Doctor Who's arch enemy lmao "Dalex" very cool old stereo i still have the first turntable i bought in 1981/82 a Pioneer pl 200 still works perfectly
The brand name Dalex is older the the Doctor Who´s enemy Daleks. The dalex company produce high quality welding gear since 1945. But it sounds funny. I like the Doctor Who television series.
Totally unexpected…your demo record, the Clancy Brothers and Tommy makes traditional Irish music. Liked this video very much. Less complex repairs and electronics still valuable to many of us.
Here's a tip if your clamp meter doesn't go high enough connect 2 wires in parallel to one of the outputs, measure one of them, then double the reading ;) To measure a low resistance, connect that resistance in series with a known resistance, apply a voltage, measure the voltage drop across the low resistance, then use ohms law
At currents that high the two wires in parallel need to be as equal in length as possible. Pretty difficult to accomplish to do that. Even a slight imbalance will greatly influence how the two currents are distributed among the wires.
@@vbinsider That's a given, like both wires being the same size If the result is critical, you could measure both wires individually and take the average
@@sparkyprojects Are you sure you mean you would measure the both of them and then take the average? I feel like the answer would be to measure both of them and then add them together and that would be your total current for the circuit
10 years... I remember when I was watching your videos like 7 years ago on my old account. I think a year ago I found ur video and the intro reminded me of your old videos.
I agree with you completely on your intro. I really enjoy turning other people's junk into something useful and repairing throw-away appliances. Not too many like you or me out there. I watch all your videos, maybe not the day they come out but will catch up on a "rainy" day or on a day I just need some rest. Thanks for what you do,
The old GRUNDIG Hi-Fi gear is amazing. Both the amp and the tuner are made in 1965 , their predecessors were the SV50 and RT50 . The SV50 were the absolut first transistor stereo amp in the world which become series production. In those days Grundig was a major player in the world with abt.40,000 employees at 7 production plants throughout the world. I remember the days when our local radio dealer got this setup in his shop displaed . it cost a fortune, unobtainable for me. Years later I got the bigger brother of the amp , the SV80 and the RT40 radio tuner from a neighbor who had this componets stated defect and bought himself a new equipment. After a carefully inspection of this service friendly gear, it were only a blown fuse in the amp .New fuse and the setup run like new. I should mention that Grundig use only RCA semiconductors in their products. RCA made high reliable semiconductors in those days.
Whats reality TV?!?!? Love your work. Love scrap yards, old tools and old audio equipment. Very good looking Grundig amp setup and the white was a good choice for that cabinet! I use a Sansui 60's valve amp that i've had for about 20 years.
One thing to keep in mind about "fake" things from the that era isn't that they were necessarily trying to be faithful to it looking like an item. Plastics as an industry were booming, so they were marketed as something of a status symbol. Everything from fake wood-grain laminates, to plastics flowers, to dinner- and drink-ware to appliances. One of the appeals of plastics was they were available in virtually any color and could be made in virtually any shape.
For the chunky transformer, You can use a simple chisel (or a sharper one intended for metal) to cut through the copper. This way, you wont generate dust and scatter the copper everywhere.
“Grundig was one of the biggest players” nice pun 😊 The plug on your spot welder, was made by Harting. We used many different types of these in the injection mould industry.
I very much appreciate the historical references such as the town that designed and built Dual turntables had a watchmakers tradition. That’s the kind of tidbit that brings viewers back to your channel. I grew up surrounded by Garrard and Dual turntables and was fascinated by their mechanical “wizardry “ as you put it. I expect you will resell that stereo and I imagine you will sneak a Bluetooth module into it to make it more useful. Maybe not. A good place to find a buyer would be a retro vinyl shop which seems to be a growing market these days at least in the Seattle area. Thanks again.
Happy you were able to rescue the Grundig Hi Fi. Would like to have owned a Dual turntable. In the 70's all I could find at my budget for my projects were the ubiquitous BSR turntables. I appreciate the time taken for this repair -a - thon, and enjoyed the ''restoration'' project the most. Maybe that style would be less demanding and would free up more of your time ? Vielen dank Gerolf.
That connector on the Dalex spot welder is likely a Han connector made by german company HARTING! They produce very unique modular connectors both in Germany, and in their facility in the United States, often these are used for high voltage machinery that may need to be serviced as an alternative to more permanent and difficult to remove connectors. I worked for HARTING for a short bit and was very impressed with not only their bespoke engineering process for unique connectors, but their absolute german organization and attention to detail. It is no surprise their connector has held up in this application, I hope you'll be able to use more of their connectors in the future!
You didn't destroy a wrench. You modified it for clearance. That stereo system looks fantastic, and I'm not surprised that it "just works." I like the format of segments versus presenting all the finds and then going thru them.
1:30 ‘The victory of the vapid and the mundane’ How you have the nail on the head sir. If only the young Tik Tok addicts would take a minute to understand that too.
Hey, friggin' awesome work on that Dual turntable :). The mechanism is a thing of beauty and a joy for ever. Incandescent bulbs don't really flicker, as the filament has thermal inertia and simply can't react fast enough to flicker at 50Hz. Fluorescent lamps, on the other hand, were a lot more susceptible to this - and that's why you get fixtures of two FLs in industrial settings, one of these lamps is phase-shifted relative to the other by a capacitor in line with the lamp. Otherwise you'd get a stroboscopic effect making rotating parts seem like they're still, leading to workplace accidents.
Totally enjoyed today's video. Back a half century ago I sold high end stereo components. My favorite turntables to sell were Duals. As you quickly determined hardened lubricants are a problem on older equipment. Another issue that often arises with use is worn, or hardened, rubber drive wheels. Back in the day they were not particularly expensive. Don't know about now. Thank you for enhancing my retirement. ;)
I'm 73, and remember Grundig stereo components and Dual turntables. Love these videos, and as an aspirig German speaker, I really like when you toss in random German words for technical things. Keep it up!
I had several dual t/t. The first, a 1019 model. Very nice with a Shure N7D cartridge. Next, a Dual CS 721 direct drive, the absolute best t/t with a Shure V15 Type III cartridge. I was VERY impressed. This table is still for sale for ~ $500 to $1K.
Gerolf, what about building speakers for your "new" Hi-Fi? Here in the US, old Hi-Fi speakers are fairly easy to come by, but often blown or rotted through. Maybe specifically find a busted set and show us how to redo the surrounds on them? Refinish the cabinets?
I worked in Fords many years ago , they had spot welders on the car production line. These spot welders were fitted to over head gantries and counter balanced. The worker would use very little effort to move them around. Years on these welders and gantries were removed and robots fitted ,,, getting rid of staff and keeping the production line working 24hrs per day seven days a week. Loved the old music system,, im playing with old Xboxes and video games. Would love to see you repurpose one of these.
Dalex doesn't want you to have information too repair there old equipment they want you to buy new equipment from them. They are in business to make money not to help you repair the old equipment! It's the same over here in America. I enjoy watching your channel It's very informative. 👍🏻
Thank you for the Dual turntable repair! I have two (dual Duals, you might say) that I hope to repair. I'm sure your information will be super helpful.
The stereo restoration brother.. Beautiful work!! Been following you for years since you fixed that PlayStation 1 you found in that Ebay junk box you bought years ago!!
Absolutely great video! Those were some serious Amps you worked with! I especially loved your restoration of the Dual record player because of personal memories. Thanks Gerold!
Very entertaining, especially the hum from those transformers when you crank them up. Thank you for putting this together to save us from doing our own experiments without having your expertise. And you are forgiven for the spanner melting too, as some tools were never any good, so we might as well have some fun.
hey gerolf, in respect to your intro, there's a word for that feeling of false normalcy-hypernormalization. for reference, that word was coined by the fall of the soviet union. it really describes what I've been feeling for the last three years.
Latelly i've fullfilled my dream to be a guy that can repair everything. My gf firmy believe, that i can handle all of the repairs. Thanks pai for inspiration
Im in the midwestern US and work on a lot of west german and some east german radios sets. Its amazing how far ahead and higher quality that stuff was compared to the us at the time. One thing I would like to warn you about is the crappy ERO capacitors in your radio and amplifier. They like to short and explode.
In the early 90's at Technical collage we messed around doing a similar transformer destruction, trying to blow up large electrolytic caps. Gave up when or huge (50kg+) transformer drew to much current and melted a 32A extention cable!
Loved the 90% mechanical control logic on that turn table. It's also cool to see one that DOESN'T have a rubber belt drive to go hard (Causing inconsistent record RPM), or to eventually disintegrate into chunks and get stuck on all the mechanical parts. Designers today would have wanted to use multiple motors and more processing power than was used to get man to the moon ! :D
I was just talking with my daughter about the repair/ rebuild ethos. She was talking about how GenZ in the USA has essentially no prospects for upward economic mobility without a trust fund, so is relying on DIY and repair/rebuild skills to improve their standard of living. I mentioned how I also feel it is a moral imperative to repair and reuse (if possible) as a good use of resources. I referenced your channel and all it has taught me about repurposing/ rebuilding equipment to be usable again.
Those speakers look like KEF's. BTW, if you want to repair the grilles on the tweeters, try a vacuum cleaner suction pipe on it to pull out the screens.
For rewinding transformers, if you are not willing to invest in magnet wire, you can remove the thick PVC insulation and replace it with heat shrink tubing. Most that would cover this thick wire has a voltage rating starting at 600V.
The HiFi cabinet looks so much better in white, Actually more modern. ng Power meters you found were interesting, In many ways the older unit looked much more interesting.
Hello playing with those transformers making big currents reminded me of some high current testing work I did years ago on current transformers for distrubtion systems. We had to test at 20 times rated current around 8000 amps through the single turn primary we where testing.The LV supply cables had to be fastened carefully as the magnetic fields would push the cables apart violently. It was a interesting job being paid to play with with transformers and your video reminded me of those good times .
A friend of mine who plays music, loves Braun SK55 from his childhood home designed by The legendary Hans Gugelot + Dieter Rams, in 1963. My old freind's name - Hans Zimmer :-) ( I think he plays music in movies now not sure if he is really famous?) That dual/grundig pair embodies everything good that is German!!
Dear sir, I greatly appreciate what you do, and am heartened that there is a person and persons who also repair and reuse. It is a great and noble calling to preserve and prolong the use of things, especially well made things. Things once made with art and intention and craftsmanship. Which are scarce or pricy these days. Thank you
If you do build a controller circuit, it would be pretty easy to use it with one of the modified MOTs and a current transformer and external button. I bet 200A is more than enough to spot-weld nickel strips onto 18650s. Also a diy milliohm-meter is a pretty easy project, and a rather useful one for troubleshooting.
in the US a record player was an all-in-one integrated device, amplifier and turntable (sometimes a radio), since these are discrete items what you call a record player is a "turntable" in the states
My initial thought on the other signal wire was that it might be a thermistor in the transformer to detect overheating during heavy use.
Oh, of course my favourite TH-camrs watch eachothers content 🙄
I'm glad that Big Clive is a Post Apocalyptic Inventor watcher
Spot welders are usually only on for fractions of seconds. Hard to get them to overheat...
@@jackmclane1826fractions of seconds over thousands of hours of continuous duty add up don't they
It make sense, but when Gerolf said the box can stop the current after some time, I thought it would be a sort of current sensing, like he spotted.
Watching the magnetic flux from that big transformer move those huge wires on the secondary side is awesome
Today I learned that 3mm TIG rod is just a naked 200A slow-blow fuse 😅 But seriously thank you for all the pulling wrenches and moreso for the wisdom you share.
So Russians with their nail as a fuse were not that far off after all XD

Also a diy milliohm-meter is a pretty easy project, and a rather useful one for troubleshooting.
Old stereo was a real nice find.
...and that is how TPAI grew into a business making shurikens for the German army. 😁
I'd have the Black Out record on that turn table in about two seconds.
What a beautiful hifi so practically designed

I always KNEW you were a connoisseur.
Aha - a Clancy Brothers & Tommy Makem album! My dad had a bunch of their records so I grew up with them in the 60's. Great episode by the way.
That Lidl magnetic pan :) Good stuff.
There's nothing like an older stereo system. The newer ones just aren't the same quality. 😀👍
My Grandaunt had several Clancy brothers records, I did not expect to see one on this channel...Grüße aus Irland.
