Hi
What op amps do you use?
In my Supra 2.1 version (2.1 because I use smd) I end up using ADA4627-1. As I described earlier here, I had a problem with bipolar op amps.
I am currently working on my Supra 2.2 version. I decided to replace four op amps with two transistors in the input stage. I asked Andrew, the creator of the X-Altra MC/MM Phono Preamp, if I could use his idea and now the latest version will have JFE2140 at the input. I already have the PCBs at home, the minimum order is 5 pieces so I can send 3 pieces for the cost of shipping. I am currently waiting for larger purchases at Mouser to have free shipping.

Just to let you know I have 20 of these PCB's .... so could send you you a couple at basic costs to cover postage
