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?

I like the old Heathkit receivers. Heathkit produced some of the finest of the time. Most are very easy to restore(since they were built from a kit most of the time) and they are all built like tanks. Power wise, they were under rated. You could always depend on more than the spec indicated. I remember using a AR15 receiver to drive a pair of old Acoustic Research AR3A's. It would make those VERY power hungry speakers jump off the floor and fill the room with great sound even into their <4 ohm load. They always had superb tuner sections. Unbelievably low cost for what you got if you were willing to invest a little time in construction. Later, they offered a few assembled models. It was a lot of fun building those things. I still have the AR15 and a few others around. Hard to part with history and your roots!
