Modding a NAC 202

[Roog]

I am looking for a pre amp to match my existing Naim preamp. I have read a few articles which describe modifications for the CB and olive range up to 102. I wondered if anyone had modded a NAC202 which has the classic case work and would be a better match visually for my power amp?

It is essentially the same inside as a 102, so anything you read on that pre-amp can be taken for the 202 as well. Simple options include changing the values of the Time-aligned input filters to those used in the 82/282; adding a VBE filter to the NAPSC; taking the 0V leg of the feedback cap in the gain circuit back to the main 'star' 0V point; splitting the HICAP circuit into two separate sections, etc, etc. All and more can be found in the DIY this section or on the Acoustica web pages.

Thank you Jo, this is very encouraging and thank you for the list of things to look out for.
