Technics Amp repair with NO PARTS! 

Couldn't have said it any better!

So relaxed and informative. A winning combination. Dave Jones must be rolling in oscilloscopes, his output is BORING. 🥱🥱

What spray do you use in the end of video?

I know next to nothing about electronics, but there's something so appealing about Mark's videos that I can't stop watching. Can a 64 year-old like me learn a new trade? Mark's videos give me hope. 😀

I totally agree with you. Mark mends it with smiles for miles.

Hi ! I'm from France too, and i don't agree with you, because in france we have ''repair café'' to repair every thing, and we have a lot of people interesting with that ! just for information , regards, and congrat to this guy for showing how to repair !👍

@@jeromelefevre8000 hello, vous pouviez aussi le dire en français puisque c'est notre langue 😝 😝

Sounds like it would be a good place to open up shop. Here in the USA, there are basically NO electronic repair shops existing anymore. Once the word got out that I repair electronics, I have so much work that I could quit my day job, and support myself with electronic repair only. There are still plenty of people out there with expensive pieces of electronic gear that they would like repaired.

I use a great hifi repair shop in Nîmes. So far they’ve been amazing

Hi from Athens! There are still electronic repair shops, which most are in industrial places, there’s a shop in north Evia that repairs and sells collectible old tech.

nice!

Are thy common to fail or something? The sound quality difference between analog and digital is huge on my amp. So much crisper with digital.

@@proudofyourroots9575 maybe you´re hi-fi equipment is unique, or you don´t have a good analogue source to compare it ,as an example i restore 3 of my old decks and i remenber when starting to win more money i bought for the first time a black component stereo system ,i first invested in a ES system from Sony this because since 76 i had been using everything in light grey or brushed aluminium and i already had a pioneer PD-7300 cd player bought in 87 (i think)and bought the most expensive and well talked about cd player from CEC(chuodenki) a belt driven cd player but when i recorded from cd to a TC-K909ES cassette deck, the cassette ,a tdk sa-x it sounded better than the source also my old turntable was really good sounding a PLC-580 from Pioneer and invested in some pair of huge speakers from cerwin vega made of wood with a lot of veneer (believe it or not the red menbrane in my two woffers didn´t rotten as in all cerwin vega speakers i saw from the regular series) ,they cost me at the time each,what today is 1.000€ and a bit more ,the convertion is not perfectelly done, this to say that my 77 turntable and my deck ,modern at the time and high-end of Sony in rock music or music with guitars the cd always cuts the vibration of the guitar chords, the amplifier was a TC-F690ES(or close to it) from early 93 which ,don´t know the reason why ,only in Portugal and the U.K. were sold with two huge power transformers and two also big capaciteurs, the sound was really clean but digital wich i had a DAT deck after the reel to reel deck it was the best recorder i remenber having , the cd player also with lot´s of cds sounding perfect ,not those analog freaks that analog is the best and always buy vinil . well i do have around 9.000 LP records but also have 4.000 compact disc , and what i like is to hear musique with quality ,that i already had in my 76 system but so tired of looking at it, allthough everything works today with perfection , i arrived to the conclusion that digital is in a good path but not evolved as the analog , one can have a complete digital system but the sound is always analog or we wouldn´t listen to music but the sound that the spectrum 48K used to do when charging a game, i believe in you but maybe a singularitie , i can add that some of my friends have expensive cables from rca to optic fiber to conect digital or analogue source´s but it´s weight it broke the digital input on their amplifiers and i use a section of cable tested and proved that it´s the best cable for processing sound but not with a heavy protection, kind of regular cables with a bit more thicker copper cable. Today i record cassettes again. I found around 8 boxes of 10 cassettes from TDK most of them SA-X but also have SA ,CDing type II ,AD-X type I and D also type I and either than my sony deck i had a CT-959 from pioneer and a DRM-800a from Denon, and i make compilations and they sound so good ,even the minidisc that i have 3 decks seems always the same sound but good ,i also bought boxes of 10 minidiscs from TDK when minidisc in my country failed to atract the consumer, so there are good analog sources or maybe all and some digital sources to, but limited to some weird sound of the guitars that when listening to the same LP in a vinil record it sounds like a real guitar, like when we play at home ,with digital is not possible but each own to it´s own ,if one is happy with what he has one shouldn´t look for better, regards

@@RUfromthe40s jesus christ man, learn to communicate on youtube. Writing essays no one will ever red. LMFAO Only time analog sounds better if its an analogue instrument. Any modern recorded media goes through a DAC. Theres no pure analog.

@@proudofyourroots9575 No, they are not. It was just a humorous statement. Digital audio is very reliable.

Absolutely test / calibration equipment envy... 😊

You will suck his tool.

I believe this is a remnant from the 90's, when the first RoHS compliant solder was introduced. You had the same with automotive components. Especially those that got a lot of heat cycling, like ABS-modules.

Yep. The switch over to lead-free solder was to blame for most of this.

Hi, was that general maintenance, no parts, or was something else e.g. no input? Thanks, best regards.

@@franciscorompana2985 No parts needed. The only issue with mine was the fan noise and I was able to repair that by removing the fan, disassembling the motor, cleaning the dust buildup and adding new oil to the bearings. The only tricky part was that there is a small plastic bump on the bottom of the plastic shroud that holds the motor. The motor has to interface with this bump correctly, if you don’t, once assembled the fan blades will interfere with the housing. It’s trivial, but it is a detail that can’t be overlooked. While I was in there, I also cleaned and replaced the thermal grease on the heat sink.

lol im running that exact setup (minus the TT). Mine is the g91 from 1991. Everything works flawlessly, except one of the cassette decks. This deck fortunately isnt one of the cheapo models they produced just a few years later (so its worth fixing). I think i saw a receipt for the set up and it was around $600 (on sale) and that included speakers in 1991. The guy i bought it from barley used it. I got everything for about $80 about 10 years ago.

The magic of video editing

They certainly are...those tape decks...but amp is still going good after 32 years..sux120.speakers still proper!
