Nac 52 phono board removal

Firstly, does it have phono boards fitted?  If so, then it's very straightforward once you remove the cover - be careful with that, you don't want to catch the polycarbonate fascia as you slide it out as it could be quite brittle by now - you just pinch and release the plastic locator tabs and then lift each daughter board up and off. 

Hi Richard, yes it has K mm phono'S. I think 525?? Thank you for your instructions. Any idea about the input socket for the Cds2, I have done a search on the forum and everything seems to refer to the older nac 52's. This one being almost at the end of the run I was thinking things maybe different? Also I'm  aware of the record muting benefit.

Thank you

Sorry they are K 523. Anyway pull them out easy thank you Richard. I'm Just using the 52's cd input seems to sound fine. Do not want to play around that amazing but brittle hiline to much. The olive preamps seem to have a very tight din socket compared to the cds2's out put din socket for some reason.

On the early NAC52s there were more daughter cards so it was possible to fit, say, NA528 boards, which are totally unnecessary on a high quality CD player like the CDS2.  

The NAC52 inputs are actually numbered and you could label them as you wished - a sheet of sticky labels came in the box.  Any input is fine, but I wouldn't use one of the tape loop input/outputs unless that was all that's available.

I was able to pick up some "through boards" and use the phono input as another non tape input. Old Denon CDP is through it at the moment.
