Anyone Still Using...?

Hi All

I'm still seaching for any other user of a Nagatron HA-9000 dc phono pre-amp. This was a late 70's device, reviewed by Julian Hirsch in Stereo Review. I have a copy of the review, as well as the equipment. Mine has the serial number 1108 so one would guess there must be more out there. It is still in daily use, I have other step-up devices but always prefer the Nagatron. This obsessive question has been posted before on other fora without response.

Cheers
