I used to have a Pioneer SX-1280 with a Technics EQ SH-Z250 pushing Cerwin Vega RE-25 Tower Speakers. I really enjoyed & loved that stereo. Had to get rid of it. I chose to take care of some family before they passed. I knew it was a good sound system, I just didn't realize how good of a sound system it really was! You only have one mother & father.

70s Matsushita capacitors are very stable. I know theyre not forever but I would trust these over any others. your videos are great, thanks to you and a few other fix it guys on youtube I can now fix my own amplifiers and electronics.

Back in the early 1970s I had a wonderful analogue FM stereo tuner with Dolby FM, connected to an extremely large external aerial on a rotator.

Why don't people take care of this great equipment??!!
I recently dug up our old Pioneer Amplifier, and radio tuner from our shed, it would have the cassette deck but my dad gave that to the thrift store back in 2013.
I had a SA-5370 receiver, had from 1978 till 2004 , with sl 1900 direct drive turntable and Lafayette speakers, sounded great. Wished I’d held onto it did the same job you did clean up the controls. Bought newer Sony 5.1 box set , didn’t have the same sound , at the curb when I moved out. Of my fathers house, I regret leaving it along with my lps , Needed room for more “important “ stuff.
Wow! Condition of this unit is excellent even the sticker at right corner is in its place. Another greater video after Panasonic RX-DT680 boombox video .
Nice receiver. I also have a Realistic STA-100 from the 1980’s made by Radio Shack and it works like a beauty. I can’t go to stores because of the pandemic going on.
Gotta admire folk who keep the original stickers on stuff. Extreme example: I remember one of my friends after his parents had purchased a 28" Sony Trinitron - full NICAM digital stereo, Fastext, matching VCR - the works! Whenever I went round their house they still had the transparent orange 'It's A Sony' logo sticker (the one with the dots) stuck to the corner of the screen! This persisted for well over a year!
That's a real beaut! The dial string arrangement is very similar to the one in my Grundig Studio RPC350 music centre, very complex. The "string" on that though is actually 2 woven sheathed wires that powers the illuminated cursor & has never been quite right since I've had the thing! Even so I prefer it to a digital tuner.
Its good you have wallk in stores to buy capacitors ect, there is no where round where i live(UK) like that it was always mail order now its all on line.
I have a SA200 that was my first purchase of a receiver back in 78 when it came out. I use it for archiving vinyl and I have not turned it off for a good 18 years now. It stays on, but is only used for the preamp. What is your thoughts on leaving it on like this? Never had an issue with this machine but for a rectifier being replaced back in 82.
Just a beautiful mint receiver! These were still built to compete with Pioneer and others, with a decent analog tuner and a classic all discrete amp with no STK power module, no caloducts, just serious power and clean build. The only problem is perhaps the wires that are not specially cleanly arranged and the lack of shielding, but it's perhaps more technicaly easy to maintain and access that way. Great sound anyway, even with your neighborhood vacuuming noise... Just love to see others like these, where there is virtually nothing to do 40 years later. You say the filters caps are done, but I guess numbers are still fine (no stress?).
Just found a SA 5470 in almost as pristine condition as yours for $17 at a thrift store, along with a working Technics SL-1700 turntable that some idiot priced at $6 because the cartridge needle was broken off. None of those dark blue caps which tech's say are so crappy have failed on mine yet. Not sure about the veneer on yours but mine is definitely vinyl skin with fake wood veneer.
I have one, even has that sticker.. mine does have one very small mark on the top edge of the face.. very small but it’s there. The left channel has issues on mine .. looks like a few capacitors are maybe bad on mine as I see the plastic coating shrinking.
I’ve been using my dads sa-500 for the last 20 years. He bought it new in 78. It works great but needs a cleaning. What is the product you’re using to clean the switches?
I never heard of Nuetrol. ???? 30 years ago I used to use Blue wash tune and then the tuner maintain lube after the wash out.... Can you enlighten me on the Neutrol ??
Really nice piece! Better than the all black digital one that I have. Can you imagine the nightmare it would be if you had to restring that tuning dial?
I have the same receiver. It runs very warm, but performs and sounds nice. What could make it run so warm? Puts out heat like no other I've owned. Weird.
What can we use as cleaning liquid? My sony tc-we705s tape deck is working wrong. When i press right direction play button it is playing left direction. Probably buttons has died..
I am located about 45 minutes south of Chicago. I'm guessing based on the radio stations you are in the Chicago area? I have a Technics Sa-700 in beautiful original condition (father's) that needs a good cleaning on the contacts/switches. Would you be able to give it a good cleaning? Thanks in advance.
Sir, I have a Sansui G5700 and the Varistor STV 3H is faulty and I can't find a replacement anymore. Could you please tell me any alternatives for replacement of this component. I'm really desperate right now. Thank you and God Bless..
Think you could make a video on how to set the tuning wire correctly? I know it will currently help me and possibly others. I haven't been able to find any, so you would be the first. Thanks
Nice, top-quality receiver from the 70's. "Digital delay" is something I also find annoying. _ALL_ signal processing (at least with practical bit rates) introduce it. Of course, it has some advantages, too..
I have a Technics SA 5570 stereo receiver that is in nice condition. The last time I used it, which was many years ago, it worked fine. Recently, I plugged it back in and the volume is quite low even with the volume control at maximum. Any ideas as to why there is so little volume?
Can't beat the early Technics gear. Unfortunately I didn't get to buy it until the 1990's and to be honest it wasn't nearly as good as the earlier stuff. Perfect match for the 676 cassette deck you did a while back, guessing they came together?
Way to go with the analog tuning dial,,,realigning the oscillation to tune station to the correct frequency number for the station broadcasting. Might want to adjust the 2 fm sensitivity trimmers,,,while tuned into an fm station,,,and watch the signal strength meter reach it,s furthest point for the maximum strong signal,,then it probably will receive any station without the antenna connected.
my amp's right channel got distorted at volume at 8 oclock dial but when i reached above that dial the distortion is gone,i experienced it when turning on the amplifier or switching the input selector,what to do?
Loverly unit dave :-D, i'm much like you in liking analog systems. Analog is human, Digital is torture lol. I have a toshiba tuner with a thick aluminium front, it has the simple design of scale and lighting. Behind the glass there are two real meters to the left, tuning and signal. There are 3 small push buttons for am/fm stereo/mono and a tone generator. I have a pioneer sa-706 amp with thick aluminium fasia and real meters. Maybe one day i might be able to listen to it again with my knackered ears.
Did anyone ever tell you that your beyond annoying? You race every time the man post anything to "attempt" to say something to kiss his behind. Ever wonder why he hardly answers you? Because he realized too that your a pain in the ass that won't go away. SMH.
That's cheating! All those pots are highly accessible. I have a few of each, SA700's, SA600's, SA505's and one SA500. If you come across one of those to feature, I'd be very interested in seeing what it takes to get to some of those pots under the board.
Caps are fine. Esr was never an issue until switching power supplies. People think caps are the end all. Inexperienced a d unqualified start changing every cap because they don't understand the symptoms of bad caps. The old guys with decades of experience know that caps don't fail that often. They do occassionally go bad, but they were always in specific circuits like the bootstrap or ramp cap on vertical circuits or the odd main ac filter. In tube circuits the DC blocking caps (paper / wax caps) were common. But in big linear amps like this they very seldom fail and when they do you will hear it. No need to measure. These are such high values the esr tester won't measure it anyway. Once you get beyond about 4700uf it is pretty useless. Again the old timers know what I am talking about.
Why swapping the bulbs with LEDs when they ain't broken. I mean LED light is more efficient and stuff but hey, there's still no LED that has the nice red glow that incandescent lamps have if you like warm white light. I hope we'll get CRI >99 LEDs soon. I would prefer cold white, around 5500K. Would make it look modern vintage!
No intent to swap bulbs with LED. Can't beat the look on incandescent bulbs. If they burn out and I can't get replacements then that is a different story.
theres big fans of technics panasonic audio gear i am too Matsushita !! oh quasar too same company lol! i think they also make a 330 watt pr.ch monster look it up hi fi engine ....
Plasma have high speed switching and hv discharge so yes they create much rf noise. They also heat the room up nicely as they suck back a fair bit of power. They do have a beautiful picture. My Samsung 63" is 12 years old and just had a minor hiccup a few weeks ago which was a 10 minute fix and it is again working great. I'll keep it till it blows up.
