HI Richard, thanks so much for your reply. It is possible to purchase a NAIM Phono board for this preamp? I think this is the reason i am not getting any signal from the phono imput after connecting the LP12.
these other boards you mention are they costly to replace?
HI Richard which version S,K, or E do you think best fits a LINN LP12 and a Candid MC Cartridge with the EKOS SE2 tonearm and a Radical PS. Ebay has many 323 photo stages but just found a NEW 523 K pair of phono boards NEW still in the box.
yes i just saw them still in the box but you are correct that does not mean they do not need an update once received. The price the seller is asking is about double what similar boards have been selling for in sold items plus shipping from England
Another alternative would be to take advantage of the powered AUX2 input on the NAC52 (this gets dedicated power rails from the 52PS) and use a Stageline K, or a secondhand Prefix K. The Prefix would be my personal choice, as I presume you use an LP12, and fits within the LP12 plinth. Only issue is finding one and making sure it has the Linn SME connector rather than the connector for the ARO.
AIUI, there are two boards, one per channel. Richard posted this pic ( from Kuma, I believe) about four years ago . .
You can see the edge of the second board, and what looks like an “absence of metal” (a large hole) directly underneath.
The NAC52 used a pair of sandwiched main boards. For the Phono input, one daughter board was positioned on the top main board and the second daughter board positioned on the lower main board underneath. Obviously, the only way the second daughter board could be fitted was via a hole in the U shaped alloy chassis tray.
I may have an image of this somewhere, but it could mean looking through thousands of pictures in my Naim picture files…
