I was replying to Neil S. I just wondered if some of the 32.5 cards had been substituted for the original 12 cards. As you say a picture should reveal all 
Hi James,
The 12 would have a pair of NA321s (gain) & a pair of NA324s (input buffer), plus 325 switch on delay & phono cards.
A 32 would have the same cards, plus an extra pair of 324s for the tape output buffer. The 12 has the tape output connected directly to the input selector.
So other than perhaps a newer revision of 321/324, there would be little advantage to swap them out.
It would also not be possible if the 12 has the early “knife edge” connectors, rather than the later pin & receptacle arrangement.
Regards
Neil.

Cheers Neil - that’s interesting info.

As promised, pic of the inside.

Shows the two red power wires that seem to be wired to the same track on the underside
Makes sense we have the pin and socket cards on my board.
Hi Lennox,
If the two reds are indeed terminated to the same track, don’t go connecting a flatcap, hicap etc. It will short the two rails together & the power supply won’t thank you for that.
It doesn’t look to me like the modifications were done at Naim, we wouldn’t use that type of DIN socket or stripped out telephone cable for the earth.
I’m afraid you will need to bite the bullet and get someone who is competent to sort it out for you.
Regards
Neil.
