Then why do I see a flood of "vintage" audio electronics (not just turntables) on eBay etc. selling for ridicoulus prices? Lots of it is junk. And theres even speakers that were designed 60 years ago.

One man's junk is another's gem. Some vintage audio equipment was junk when new, and it's now just older junk, but most gear was built with reliability and serviceability in mind. Many dealers back then maintained their own service departments that had to fix the stuff if/when it broke, so these were priorities for those dealers. I have several pieces of gear that are 20+ years old, and a few that are 40+. They worked and sounded great back then, and they still do, despite the ubiquitous use of - oh,
NO! - many much-maligned electrolytic capacitors, none of which was ever replaced with more "transparent" caps. Failed caps - few and far between - were always replaced with equivalent parts.
A few of my vintage components have required service over the years, but repairs were generally simple and reasonably inexpensive because of the way they were designed built. I was able to perform many of the repairs myself, and only considered replacing failed components when newer gear offered genuine, audible performance gains or enhanced capabilities, which really haven't come along very often. (I'm talking strictly about audio gear. Video technology has advanced so rapidly over the last decade that replacement has become preferable to repair for most, including me.)
