Mine is a standard, CD-63SE. Most noticeable difference is the transformer, but I also spot some capacitor differences. This is still used in a bedroom system with a Nait 1. I tried it last night after swapping some speaker cables over. It still sounds remarkably good.
Inside my new, to me at least NAP 140 circa 1999.
No idea if it’s been serviced or not. Sold as not, and will be heading north in Jan to get it back to standard.
Any ideas from these pictures?
I am going to say its un-serviced. I read recently on here (?? - @NeilS) that BHC caps were discontinued some years back & replaced by Naim, with ANOther type.
Where i was. The soldering in the first picture, on the NAPS140 board ( top left) didn’t quite look like the work of Salisbury! Where the caps connect to the board. But it could well be.
