I'm doing some maintenance on my beloved 1970s Technics SL-1710. This includes recapping the main PCB, replacing the tone arm lift dampening fluid and general cleaning & lubrication. // Kindly sponsored by my favorite PCB manufacturer PCBWay! www.pcbway.com/
Service Manual for the 1700 and 1710:

Electrolytic Capacitor List:
470uF 50V axial
33uF 25V radial
10uF 25V radial
4.7uF 25V radial
2.2uF 50V radial
3x 1uF 50V radial (replaced with MKS caps, see below)
3x 1uF 50V radial bipolar (replaced with MKS caps, see below)
0.33uF 50V radial (replaced with MKS caps, see below)
0.22uF 50V radial (replaced with MKS caps, see below)
I used WIMA MKS2 metalized polyester 5% 63V 5mm capacitors to replace the smaller value electrolytics and the bipolar capacitors.
I replaced the large 470uF axial capacitor with a Vishay axial cap.
For the other regular electrolytics, I went with Panasonic FC series capacitors.

The original thermal grease that Technics used is non-perishing, I recapped my SP10mk2 (made in 1980s) in 2020, and the thermal compound was in perfect condition. I also worked on a Technics SU-3500 integrated amplifier from early 1970s, and the thermal grease was in perfect condition as well.

@JanBeta 6 месяцев назад

Yes, the grease was not dried up in this one. They must have used really good stuff back then indeed! The only portion that was completely dry was the part that connects the heatsink to the case. :)

I have a SL-1700 that I bought new in 1978. After 46 years, I think its time to replace the caps, especially those leaky pesky Matsushita ones. I know many people say don't fix what aint broken, and the caps look ok, but at near half a century why take the chance? Especially since I've babied the thing its whole life. I realize the 1710 is just a 1700 but in black. Appreciate this video!

I bought an 1710 a few months ago and I like it very much. Brought it to the service for RCA cable replacement and oiling but if I had found this video earlier I would've requested the capacitor change and would've tried to do some of the work myself, at least the oiling and dampening fluid. I am saving the video for further work on it. Thank you!

@JanBeta 5 месяцев назад

Nice! These things are really great turntables indeed. The capacitor replacement makes sense as I pointed out because it (hopefully) puts less stress on the IC. Hope you have a lot of joy with the Technics for a long time to come! 🤞

Thanks for this video. I have been waiting a long time for a complete restoration video for the 1710. I have one and love it very much. Will never replace it. It is built like a tank and the quality is better than Nasa's satellites 😊. Mine is from 1977 and has never been opened, oiled or anything. Works like it was new. Uses Nagaoka MP200 and Ortofon Bronze. What a sound I get. But now the old man will undergo a restoration just like yours.

@JanBeta 2 месяца назад

Excellent! Glad to be helpful. The Technics turntables from that era are extremely well built indeed. Not much that can fail if you maintain them properly, literally built like NASA satellites (also at the same time as the Voyagers, coincidentally... :D).

@landspide 6 месяцев назад

Really nice turntable

@JanBeta 6 месяцев назад

Yes! The Technics turntables from the era are absolutely magnificent. They still make the 1210 to this day (virtually unchanged from the 70s model) for a reason, not much you can do better in terms of reliability and usability, I guess. :)

Nice Turntable, nice to see what's inside. The Engineering of these things always amazes me. I have A Technics 1500 , which sounds excellent, but would never take it apart .

@JanBeta 6 месяцев назад

Yeah, lovely mechanics and electronics that were built to last. The 1500 is not that different from this one, I believe. They are not that difficult to take apart. Probably worth doing a recapping eventually, to make it last even longer. :)

@ronny332 7 месяцев назад

Replacing the capacitors of the power supply is a great idea. I have a 1210 MK5 (bought new, works great) and a recolored MK2 in white, looks great. I thinks it from the 80s. But since years I keep it in the cabinet, because there is always a bit mains buzz on one channel. I renewed the wiring years ago together with the pickup and always thought, I did something wrong, but was never able to find something ... the capacitors looked good, so I kept them where they were.

@JanBeta 6 месяцев назад

Definitely worth a try! If you have mains hum in the output signal it is either a grounding issue or leaky filter capacitors. Hope you manage to fix the 1210! Very much worth it giving it another try, these things are absolutely magnificent!

@bobrandale4864 6 месяцев назад

I love this! Mine is a Sansui SR-636 direct drive - Sorry, no dates were printed in the manual, so I do not know when it was manufactured. I seem to remember purchasing it in 1978, though...

@olik136 6 месяцев назад

I have some Dual turntables from the early 70s and it is interesting to see how different they are. Basically there is the electric motor running directly from the mains and everything else is mechanical.

@JanBeta 6 месяцев назад

Running the motor directly from the mains and relying on the mains frequency for speed adjustment seems to be a German approach to turntables. Thorens did the same thing with their early models. I’ve never worked on either of those brands but read up on them a bit after somebody showed pictures of their Thorens on Mastodon. Interesting!

@EdwinNoorlander 6 месяцев назад

I still love and use my 1610

@JanBeta 6 месяцев назад

Nice! The 1610 is very similar to the 1710 I believe, same tone arm assembly but with some added mechanics for the automatics. Should last you a long time still, hopefully. Maybe a recapping wouldn't hurt to keep the IC fresh. ;)

@EdwinNoorlander 6 месяцев назад

@@JanBeta yes. I have fixed de timing. The 1610 have a repeat en auto start and stop. I was looking for a broken one to make it full controlled with my own PCB. But this one was fully working on some timing issues.

Allgemein, Vintage-Tech von Technics ist immer ein Kauf wert! Ob Plattenspieler, Tape-Deck, etc. Ich rede hier von Sachen aus den 70er bis in die späten 90er, denn ich finde Technics hat Anfang der 2000er nicht stark, jedoch merklich, qualitativ nachgelassen.

@JanBeta 6 месяцев назад

Technics hat auf jeden Fall immer gute Qualität abgeliefert früher. Die neuen Plattenspieler sind wohl auch gut (vermutlich, weil sie größtenteils seit den 70ern unverändert sind). :D

Würde dann demnächst, hier bei Dir noch eine Besorgungsliste dazu einstellen. Da haben sich bei Deinen Angaben 2 Fehler hinsichtl. Spanunng und Kapazität (bezugnehmend d. Manuals) eingeschlichen.....

@JanBeta 5 месяцев назад

Ja, die kleinen Elkos sind RM 2,5. Die originalen hatten das gleiche Rastermaß. Wobei das eher unwesentlich ist, die Abstände auf dem Board sind eher größer und sollten auch mit anderen Maßen problemlos passen. Die Elko-Liste habe ich von den ausgelöteten Teilen abgeschrieben und nicht aus dem SM. Kann sein, dass sich da Fehler eingeschlichen haben (oder es gibt verschiedene Versionen der Platine, was zu der Zeit relativ gängig war). :)

Hi Jan, I use a Technics SL 1500 and a SL-1900 myself. I have already completed the work you have done on my equipment. You've done a great job! But are you sure that the modern headsells and modern pickups are better than the original Technics SH-98 headshell together with the Technics EPC-270 C-II? I've fitted the EPC-270 C-II with a new elliptical replica needle and I'm thrilled. Unlike other systems, the needle carrier does not seem to sound duller with age. Maybe you could give the EPC-270 C-II a another chance. Cheers!

@JanBeta 2 месяца назад

The original pickups are very good indeed. In the end, it's a matter of taste as with all things sound & music. :) I am not sure if my particular original pickup was compromised in some way, but I definitely heard a lot of improvement with the Ortofon. Clearer high frequencies and tighter bass response in my case. I used the original pickup for a long time and had several elliptical replacement needles for it as well but it still didn't sound as crisp as the new one.

@thechannel4874 6 месяцев назад

Sehr gutes Video. Vielen Dank für die wertvollen Hinweise. Eine Frage habe ich noch am Rande: ich weiß nicht, ob es der Trafo ist oder evtl der Chip oder …, aber ich höre ein deutliches Brummgeräusch, sobald der SL-1700 mit Strom versorgt wird und eingeschaltet ist. Hast Du evtl einen Lösungsansatz? VG

@JanBeta 6 месяцев назад

Danke! Das Brummen ist wahrscheinlich der Trafo, schätze ich. Bei älteren Geräten ruckeln sich manchmal über die Jahre die Windungen ein bisschen los. Dagegen hilft nach meiner Erfahrung eine Behandlung mit einem Mittel zur Platinenversiegelung ganz gut (ich benutze Kontakt Chemie Plastik 70), das du großzügig in die Windungen des Trafos sprühst, um sie quasi neu zu vergießen/verkleben. Habe ich schon bei einigen älteren Receivern erfolgreich so gemacht. Aber Vorsicht, das Zeug ist tatsächlich quasi flüssiges Plastik, wird seeehr hart, wenn es trocknet, und stinkt erbärmlich. Ich empfehle so eine Behandlung nur unter freiem Himmel. Das Trafobrummen ist aber ansonsten auch nicht wirklich gefährlich. Dass sich die Isolierung der Windungen tatsächlich irgendwann durchreibt, habe ich nur äußerst selten erlebt.

I had a similar issue with my Turntable, SL 1600. I removed the transformer bracing, placed electrical tape around the edges of the transformer and reinstalled it into the brace. Transformer hum completely resolved. I’ve read of others having similar positive experiences.

@zero0ryn 6 месяцев назад

My SL-7 still works great, but the audio distorts badly at high frequencies.I changed the cartridge to an ortofon OM10 but its still the same :( I tried to increase the tracking weight but it didn't really make any difference.

@JanBeta 6 месяцев назад

Mh, the cartridge/stylus would have been my first suspect for high frequency noise, too. Maybe bad records or too much dust? Or maybe there’s a problem with the preamp? Not much else that could be causing the issue, I guess. The audio output should just be the output from the cartridge just going directly to the turntable outputs. Internal wiring could be an issue, too, but usually that would cause more havoc than just distorting high frequencies. 🤔

@zero0ryn 6 месяцев назад

@@JanBeta I'm using an ART usb preamplifier, I tried a new stylus, though it's not a genuine one.

@JanBeta 6 месяцев назад

Is the preamp set up correctly (MM cartridge, gain not clipping, ground wire properly connected)? There’s not much that can go wrong with the turntable and cartridge itself I guess. If you have the chance, I’d suggest trying another preamp or an amplifier with a phono input. Never tried one of those Art preamps but they don’t have a very good reputation (according to some customer reviews I’ve read). Maybe you just got a faulty unit. Dust on the records or electrostatic buildup can also cause high frequency distortion. If you have a carbon brush to clean the records before playing, that might also help. Otherwise I’m out of ideas.
