K is specific to MC, N I think equals MM (at least it does with the stageline, K/E/S are for MC). @Richard.Dane what’s your opinion on 62 vs 72? Primavera has a 62/140 and his friend is offering a 72. No info on servicing history for any of these.
Oh I see, it’s clear.
That K label notify that This Phono BNC is just for MC Cartridges, no option for MM
and now for variable input boards ( V label ), can this AUX BNC connected to CD Player, or what is the best input in NAC 72 that best suite for CD Player?
You need first to know what Boards are actually fitted - as they might have been swapped.
A K board is specifically matched with Linn MC’s. An S board is the general purpose MC board. The N board is MM. The V board is a variable, line level board, intended for CD use - but not generally preferred, these days.
Am sure most of this is in the link you were sent…? Please - read it.
Good luck finding 326 boards.
Has the 72 been serviced recently?
If not, remove the 328 boards and have the original links remade. Then sell the 328 boards. They have little use now. One use was for early cd players to allow you to " tune" the high pass filter, to make early cdps sound better. And if doing that, think about replacing the bncs for phonos.
I wonder if there is any market for 328 V boards…? They are variable gain - any filters are fixed. I had them in my first 72. If they were fully turned ‘down’, the gain of CD wasn’t far off that of Phono.
My dealer did try to sell me a pair of 328 boards when I enquired about 326’s. Not by mistake, he was trying to help.
My 72 ( both my 72s) are slightly late versions with just one set of bncs.
I had them both swapped to RCAs. For convenience really. But no complaints.
One 72 has the RCA input links remade and I use an external phono stage.
The other has 322? MM boards and my Rega 25 goes direct into that.
Might be a stretch of forum rules but I’ve put a pair of 528 boards in a box that takes the record out from my SN3 and acts as a buffer to drive a long audio line to the other side of the house and into the mu-so Qb in the kitchen. Works incredibly well!
You need to look inside for the boards. When I bought my NAC62 from the original owners, it had no boards and they had owned since new/never used a turntable so assume the dealer may have removed the cards and sold them for a discount when new.
I bought fully serviced and boxed boards for mine from Darran at Class A for less than a set on eBay.
