I think some of you are mistaken about the reliability of old gear. I own a McIntosh MAC 1700 receiver made about 1970, which I bought from the original owner in about 1993, and it has never needed any repairs. I bought a Pioneer SX-1250 (made circa 1976) in the early 1980's from the original owner, and it has only needed one minor repair (back in the late 1980's). Both work great. Perhaps some of you have purchased used equipment without carefully examining it first, or have been unlucky in buying abused equipment.
I also own a lot of much more modern gear, but these old pieces do have some advantages over the electronic processor controlled equipment. For example, they are much easier to operate, as one switch does one thing, not countless things depending upon what other button was pressed first. And they have their affect whether the unit is on or off (that is, one can, for example, lower the volume control with the power off if one now is about to turn the unit on and one wishes to not have it loud). And if one listens to FM, you will be hard pressed to get a better tuner than what one can find in classic gear from the 1970's. You don't need to take my word for this, just look at the specs. For reasons that escape me, modern home receivers typically have poor tuners. Obviously, it is some sort of business decision, as my modern car stereo has a tuner that is quite capable of picking up many stations, and it is not an expensive one.
