Old Classic Receivers: A Mistake to Buy?


I was contemplating purchasing a 70's receiver, as I used to love the construction and appearance of the Sansui, Kenwood, Pioneer, Marantz. However, when I ran this by an audio friend, he said, "Forget it."

He says: They sound terrible. The caps & resistors used before the early 90s' were dreadful. The electrolytics are drying up and will start crackling and substantially degrade the sonics. The switches and controls used were almost never sealed, so they deteriorate and make noise and can't be fixed even by taking them apart and cleaning them.

Tuners: He says that nearly all non-digital tuners used varactors, which go out of alignment and cause problems, so no old tuners, with the exception of the Mac MR-78 and possibly a few others, are worth dealing with.

I am tempted to believe all that he is saying is true, but I see a market for these items, and also know that people claim they are still using these pieces for 25 years.

What's the truth here? Can some of the techies enlighten me?

Awhile back I found a receiver in a dumpster while up in Chicago. It was a Pioneer sx 1980. Well, I hauled it back home with a suitcase strap; putting the 100 lb amp in the overhead on a 727 flite to Daytona. That was a BIG job. No security back then. You know, people saw me carrying that thing and they understood why. I repaired amps before for a living, so I will hence repair this one. Power supply blown output b-plus 65v rail =0. Well this was a tricky one because many of the small components(xistors)are matched and some are not available except as substitutions; specs are not exactly the same as oem. Also all voltages have to come up together or the power supply just blows everything. This happened many times. Drawings and service manual only available in microfich and maybe unavailable. Pioneer in Atlanta (or a serv.ctr.) there can repair these units. Mine works ok even the fm works (capacitave afc cool tuning)Generally, the unit is awesome but circuit boards are old phenolics not glass, alignment is tough-you got to set bias rite or a channel will run hot and you blow speakers-not funny when they are your favorite ones. Toroid xfmr good!
DOES ANYONE KNOW ABOUT A LATE 70S JVC MODEL VR 5555X I GAVE 20 BUCKS FOR IT IT WORKS GREAT WHATS UP WITH THIS MATRIX STUFF
I have been using a Luxman 1120A for about 6 years and never had a problem. Most of the newer stuff out there are a joke compared to the performance of the Lux. You can pick one up for less tham $300.00 in mint cond. I would buy it in a heartbeat. PS I also have a set of Yamaha C-60 amp & pre-amo and Kek C80's and a nice Yamaha C220
I purchased a Luxman 1120A new in 1982. It worked fantastically well for almost 20 years. I liked it so much, in fact,that when it finally started to "go" last year, I invested about twice what I paid for it originally to have it completely rebuilt with Black Gate capacitors and all kinds of upgraded parts. The power supply has also been rebuilt so that it is rock-stable into any electrostatic speaker. I'll take this over any receiver available today at any price.
My bedroom system for years was based on a Fisher 400 driving a pair of Infinity Monitors. (I bought the Fisher for 10 cents at a thrift store) I did not find the Fisher to have the FM sensitivity I needed so drove FM through it from an H H Scott stereo tuner. The final result was just WOW! I never tired of the sound coming through the Fisher, and while not wishing to get into the "woo-woo" area of home audio, the soundstage was such that while watching a stereo vcr ( also of course "plumbed" through the Fisher), I and my lady clearly heard and enjoyed a 360 degree soundstage. I'm not kidding about this, and I attribute this to the vcr's rendition of what I'm sure was the video's "time delay" codings on the audio track of the videotape. And in search of this phenomenon tried several vcr's. But let me tell you, when we were propped up most comfortably in bed watching a video and suddenly, so very clearly, heard pure, solid & full range sound coming from, but for the bedroom wall, sound from the sides of us and even from BEHIND us,(should be impossible, no? As the bed was solid against the wall) we just looked at each other without a word. The one thing I will say is that while I am not a member of the NRA, you or anyone may attempt to pry my Fisher 400 from my cold hands.....and if you are successful, my ghost will do its best to harass you at every opportunity. Period.
