Pieces like this are what I called the best audio in the world any vintage gear be it turntables maps recievers 8 track decks reel ro reels cassette decks the best is gear with weight and all metal and wood cabinets I really am glad to know that you are on KZread along with other guys keeping this great gear alive thank you and be safe from the storm and the virus

That’s a nice piece! Even through KZread through my phone I can tell that thing has some real dynamic sound. Also keep up the good work! Love your videos. I am learning a lot. I really wish I had KZread and this channel when I was a kid back in the early 90’s I was really into electronics like this and fixing stuff

I have this units older brother, the SA-7100. Thanks fot eh video!

I had seen and heard the sx biggest many of them had lot more problems,I currently have this sa 7150 and one before,they are super reliable no restoration required,works

I have an old Hitachi Oscilloscopes, it's also very well made, comes from Japan. One is around 40 years old and works great.

This is an amazing piece of equipment. My vintage Marantz 2265B is nothing compared to this one!

A friend of mine had an old JVC Dolby Pro-Logic receiver which had a wonderful sounding Super Class-A output stage for the front left and right channels. It used Toshiba darlington audio transistors which, if I remember right, were driven at around 300 volts. He only used it as a stereo receiver and nothing else. One day a power surge damaged the receiver causing it not to play any audio anymore, and I traced the problem back to a couple of fusible resistors in the preamp stage, which sadly are unobtanium...

Just found this in the garbage on a tv stand in the alley. I'm pretty excited considering I also have a Concept 16.5 from when I graduated a long time ago. And I found some SpeakerLabs from Washington that are worth about 300 bucks for free at a garage sale. Madness....

Damn !! That thing is huge !!!!!!!!!!!! Toshiba makes great semiconductors !

What do you think of the SA 7100. There is One close by for sale for $300. one of the turntable Channel does not work The rest of it looks to be in very good shape.

I have not seen anything like this in Germany yet A dream device

Its hude ! like those old Sansui...lovelly receivers !

Mmmmm 150W/ch. RMS :D One of the "Muscle cars" of stereo! Looks gorgeous too, inside and out.

BRAVO Perfect the Contact spray

In my days I have taken many an electronic device apart, yet I cannot

man you got skillz.

McIntosh commands even much more. I have 2 MC2105 amplifiers that command over $1500 a pice when they have new glass. New glass is still available. They are strictly 100watt amps no preamps or tuners. They were originally made in the mid 1960s. The build quality is point to point and they are bullet proof as good equipment from that era. I drive them with a MC 220 preamp.Though they are stereo amps, I run them as mono blocks. As you said, pure 100 Watts. Very very low high frequency distortion. Good bands and good recorded music sound amazing. Badly recorded bands and music sound dreadful. It does not hide mistakes. Great video.

Thanks for the tip about the circuit glue in another video. I just saved a portable Grundig shortwave radio. Scraped it off and bingo

Great stuff! Amazingly complex internals in a lot of these old system. I can see why people want these old amplifiers though - they give a richer sound etc, same reason people like tubes as well. When you first took the lid off their I said 'OMG @ the size of that central capacitor', then I realised it was a transformer lol. The actual caps are still pretty large - what rating in uF or F are they?

hey bro. if you have a receiver that puts out 135 w per channel on a 2 channel unit what would be the right speakers to hook up to it? on wattage that is.
