Very nice!
There you go a piece of cake for someone with your experience. It looks beautiful, nice and clean Kev, "scrubbed up well"
I am pleased you think so well of how it sounds, your opinion means a lot, mine adds a depth to the music like nothing else I have.
And tuner alignment! - now you have yourself a tiger by the tail - but I am sure you will master it.
Likely a flaked out transistor that didn't like new life Nice work though. You tackled a monster there. I have worked on a couple of them and they are really fantastic sounding amps.
Ever heard the BA-F1 and the CA-F1? These have a very similar sonic signature. I actually prefer this set over the X1 for musicality. They really got these right.
I just cranked it up through the JBL4412's I have in the Lab here, Holy Crap!! McIntosh what?? What an unbelievable sound out of this thing!!
Highly recommend hearing one if anyone hasn't......Simply stunning!! Its one of those "hearing things in the Music you've never heard before moments!! I wonder what the tuner sounds like??
Dumb question from a noobie..What exactly is an SCR ?Well, I have gone through this extensively in the last few hours monitoring voltages etc, I have had to take a bit of a guess as to what it might be because of course, when I fired it up, it came out of protection.
I had a couple of SCR's left over from another job, so I have replaced that, I remember the one in my G22000 went flaky......So I have had it running for a while now and its all good, I will run it on Thurs and Fri all day again as I have a big project on so I can monitor it all day while I work.
When I turned it on just now, it came out of protection a lot quicker than it has been doing so hopefully its all good now....
Can't be much else.....
There it is, upside down on the bench again!!

So are those SCRs normally located in the protection circuit like it is on the X-1?A pin for pin replacement that I have used for the 2SF656 (although overkill) is the X0402MF - note it is a TO202-3 package which is a little bulky (compared to the 2SF656's TO92 package) so will need to confirm space availability etc

Well done Kev, that can't have been easy to find.
