You have a new follower Max 😊 Did a very fine job as I can see. I have the same Pioneer SM83, just bought it yesterday. Didn’t check does it work to be honest, but the guy I bought it from, said it is in fabulous condition, hope he was saying the truth 😊. Greetings from Bosnia and Herzegovina…
I've got a beautiful Gertsch CRT-1 which is a 3-stage co-axial ratio transformer with a 10 turn pot for the last 3 digits. Most unique electro-mechanical thing I've got. Solid as a brick and dead-on accurate. Love these things.
Man that is so sick! From the massive pushrods and cylinder to the glorious old school font on the crane, just a joy to behold! I used to work on modern Jennbacher 6 series gas engines, running on biomethane, outputting 3.3 MW (electrical, about 6MW of heat generation which is the main function)! V16, 6liters per cylinder. That turbo spooling up is something else. Uncanny how advanced and efficient ICE's have become. Thanks so much for sharing
Hi Max, did you ever get hold of a schematic? I also have an A-G10 which is in need of repair. I have the original remote control which motor drives the volume control and also offers phase inversion, regards Rowan
I have a Tektronix Oscilloscope 535 A with roller cabinet in working condition for sale as well as a VTG Precision Model EV-10-S Vacuum Tube Multi-Master Tester Tool. With manuals
Independently fused MOSFETs mean if one shorts the amp just keeps on running, albeit with less output. If you were impressed by the 450, you should get a PPX1600.
I own over 250 of these, in various models / configurations. I even visited the old Gertsch building in Los Angeles, 20 years ago, hoping to find some Gertsch remains in the weeds around the building. ESI made a lot of nice ratio transformers as well, and you can buy a few of these, brand new at Tegam corporation. It's hard to beat an old Gertsch box if you want to accurately divide an AC voltage. There are a few precautions to observe in order to get maximum accuracy, but when you do, they outperform most (if not all) semiconductor multiplying D/A converters. It's easy to generate 1 Vrms, but it's tough to generate 100 uV accurately, unless you start with 1V (say, from a signal generator) and subdivide this voltage with a Gertsch box. You can generate very accurate low-voltage sinusoids, well below the noise floor of some of the best benchtop multimeters.
That must be about 20 meters of cable, i saw this scope teardown on element14 i think where they just put a coil of coax around the image tube. So you can delay the signal, and see what triggered the scope Well see the signal before the trigger pulse. But the coax probably didnt have the same bandwidth as this cable. Looks like some effort went in making it, makes you wonder how expensive it was.
Sehr gutes Video. Bin jetzt schon mehrmals dort gewesen,.interessant zu sehen, wieder Verfall und Vandalismus seinen Lauf nimmt.Dein Video inspiriert sehr…
Great video. Could you activate the automatic subtitles in other languages? They are only in English. It would be very useful for people who speak other languages. Thank you so much.
It cataracts seen it even on new vintage TV’s I restored. You have to remove the CRT completely and with a hot airgun at not to high temperature but enough to heat glue and use a plastic or a metal paint scraper to separate safely glass from CRT while prying safety glass away while keeping heat on it very slowly and allow glass to slowly lift. Then one glass is off use Acetone to remove and clean up glue on CRT and safety glass. I put new Optically Clear adhesive and start glue in center and let run out to edges while putting even pressure not to crack the glass or implode the CRT and then UV cure it. You can use a large vacuum chamber to get bubbles out. You don’t have to put the glue and can put rubber at edges of glass so safety glass doesn’t hit CRT and just reinstall.
50 years ago Fluke was Fluke, today Fluke is Fluke. What do you think from a company who change 3 times the name? HP, Agilent and Keysight. All the Agilent and Keysight instruments are pour quality, sorry.
I am looking at some VTX 1000. If anyone has corrosion under the board check the track under the audio cable that is soldered diagonally (as well as the outside edge tracks at the back). Also, if anyone made the mistake of touching both heat-sinks at once and getting a huge belting shock then check for a short on the 3 legged sensor on the heatsink. One amp i received had the wrong resistor values in the protection circuit, changed them back to 1.2K and 690 ohms because someone had put 6.6k and 1.1k, Still hunting for audio on one channel but probably something to do with the broken selector switch on the back of the bottom board, i have a blown VTX-1500 somewhere for spares. Had many of these amps over the years, lots of vtx 1200 a 500 some 1000 and a few 1500 and some 750, selling them all now. Using MC2 Lab Gruppen, QSC but i might keep a vtx 1500 or my flight case with 2x 1200 just because i love the build of these. Not a touring amp but you could add lock tight which may help a bit. A bit heavy these days but not much can go wrong with the power supply! So simple! Once i had a stack of these setup at a night we were doing, for some reason i had put a sheet of toughened glass somewhere in the stack, i remember something broke the glass and the amps moved a bit and then one of the 1200 blew up. It was just the diode bridge rectifier, can;t remember now if a wire had come ff of it or of the rectifier blew up but apart from this i have not really had any issues. I bought a load of broken ones as spares and started to fix those. The vtx 1500 i bought for spares was too dead to bother with, blown to bits it was! I also have a load of crossovers and some other cloud amps. I have an 8ch 8x 50 with zone mixer and a 6ch i think they are 6x 120W
