Friday Update.

  I haven't done an update like this in a while.
  The SAE 3022 amp left this week. It's super serious blackness isn't for everybody, but it's a very good amplifier.
  I'm embarrassed to tell you that I blew a channel of the Mission Cyrus One amp about a month ago, my fault. The amp only accepts banana plugs for speaker connections, and my proper terminated cables were on loan. I used screw on bananas on another set of cables, and because the holes are so closely spaced, and because one tiny strand of wire wasn't securely screwed down, positive touched negative, and poof! I took the amp to Joe my new service guy, and discovered a lot about this particular example:
  1) I blew a perfectly good channel. The other side had been repaired at least 20 years earlier, with below spec parts, and I was lucky it functioned at all.
  2) There were a number of dried out capacitors. As nice as I thought the amp sounded (I didn't push it very hard), I haven't heard what it's really capable of.
  3) The heatsink and outputs belong on a Cyrus Two! This struck me as odd, until a friend with extensive audio industry experience filled me in. In production runs of this sort, it's not uncommon
to upgrade parts when the specified ones run out or are one is going to complain because their amp is better than specified, as mine, apparently, is. Joe has replaced all outputs and drivers with correct ones, and recapped a lot of the amp. It will be back soon, and it's going to be awesome! The Ortofon 445 speakers left this week as well. The person who took them away has owned a pair of 443s, their smaller brothers, since 1976, and was thrilled to have found them. On final listen, I think I described them well when I said that if you love Dynaco A-25s, you'll love these.
