Din lp-stage earth for lp12

Posted by: Fred11 on 12 September 2016

A bit of an unusual question maybe;

I have a nac 12 v 2 with din-connection to the internal RIAA-input. As I have my old lp12 with a new silver rca t-cable connected through a Milty rca-din adaptor I wonder if there is any way to connect the earth to the amp, sine it seems from the sound that it needs grounding. I also have an olive armageddon connected to the lp12.

The 12 goes to a excelent recapped 160 into SBL mk2

was the question understandable?

WOuld be really grateful if anybody could help me!!!

How far are you from your Linn dealer?

Hi Christopher,

not very far.

Hi Fred,

In which case, you nip over to his place and ask him to solder a DIN plug on the T-cable. (My assumption is that the NAC "12 v 2" doesn't have an earth post).

You can't use a regular Mayware/Milty adaptor easily without a bodge.  IIRC, there was a version of the Mayware adaptor that had a flying lead just for T/T use but probably long gone now.  

Your best options are;

1) update the NAC12 with a pair of RCA phono sockets and a grounding terminal.  This was done by Naim on quite a number of early NAC12s, so it's "legit".  Naim can probably still do it for you and also give your NAC12 a service at the same time.

2) have a DIN5 fitted to your phono lead.

3) make up your own adaptor with a flying earth lead.

Thank you very much, Richard, for the excelent answer. I think it should be an adaption of rca-contacts, and a service at the same time.

Fred, Have you gone retro after the 202/200 you list?

Yes! Vintage it is. Still have my ndac-xps, lp12 and sbls. Really amase me how good the pre-olive stuff sound! I like the warmer balance and looks better than my former 202-200.

Ok. My SBLs seem brighter to me compared with a lot of contemporary offerings, so I can sort of understand. (I don't dislike the brighter nature  though). Maybe one day I will just put a NAP250 up them....

Is it possible to connect the earth to the chassis through the lid???

Eeek! There may be trouble ahead.

Think I was a bit quick there, concluding, what did you mean with point 3., Richard?

Fred, what I mean't was to make up (or have made) your own adaptor using a DIN5 plug, a pair of RCA phono female plugs, a few inches of interconnect and a flying lead with maybe a croc clip on it.  It's not ideal but it will allow you to use what you have without any modification.  

Ideally though, either reterminate the lead with a DIN or have your NAC12 updated by Naim.  My own NAC12 started as a very early model.  Then over the years it had a new main board with daughter boards fitted, then phono sockets for the GRAM input, then pin connectors in place of the knife edge ones to allow 3 series phono boards to be used. All of these were recommended updates by Naim.

Thank you very much. Is it the same even if I use an Armageddon grounded to inner chassis?
