Attitudes
Take a look at Roger Russell's McIntosh history site. The very early SS Mc gear sells well on eBay all the time. Someone here said the early SS stuff was noisy, but looking there, it appears that the first Mc SS gear was quieter than their immediately preceding tube stuff. Of course, Mc could have been the exception, but I think that opinion prevailed back in the day.
Having lived through that era (as a kid), what I recall is that transistors were first commonly found in portable stuff, and no one took them seriously for home audio uses. I remember my dad buying one of the last tube Fisher consoles, with an amazing new multiplex FM tuner. The multiplex unit was a separate chassis wired in next to the main chassis. I saved up a long time and got my first stereo, a Scott 344C. I recall the big Fisher had 35 wpc, while my Scott had 40, and I can still vividly recall one of my father's friends hypothesizing that transistor watts must be smaller than tube watts, so he was going to buy some other tube unit. Moron, but it was common belief that transistors were inferior, and always would be. I also recall feeling vindicated when only a few years later, Pioneer and Kenwood effectively put all the old tube makes out of business. Didn't feel so jolly when it happened to Fisher and Scott, too, even after they switched to SS.
Anyway, this long babble was leading up to wondering whether the prevailing attitude back then has caused the very early SS gear to be less sought after than the later stuff. Comments, anyone?
