Has anyone got a NA323-N schematic?
I thought my 323 boards were S, but it turns out they're N, and I need the gain. With a schematic for the N I could see what components need to be changed, if possible. Thanks for any help.

Standard K boards will overload with a 2.5mV cartridge which is why they produced these:
323N MM phono boards, 2 mV, 47 KΩ
323E MC phono boards, 400 µV, 560 Ω
323K MC phono boards, 100 µV, 560 Ω
323S MC phono boards, 100 µV, 470 Ω
328 Variable boards, 75-300 mV, 47 kΩ
326 Line-level "blank" boards
The 323N was dropped for the 322 BUT both were manufactured together for years. The 323E and N were discontinued by Naim ages ago. The 323E is meant for high output MC.
Also the 20x has an output of nearer 3mV and prefers a load resistance of below 300ohms. The problem with Naim phonostages is that you cannot adjust or even tweak for optimum load. I had a XX1-L years back and it sounded quite 'loose' above 470ohms. It was the same with the XX2 Mk2, so I cannot image 560ohms on a 20X is actually the best thing. It needs to be about 100 - 220 ohms maximum IMHO... and many other users
