No

Any news Ricardo?

I have more gain in the left channel so it is natural I hear more hiss there.

I did not have time to figure it out but I will.

Anyway, the FT-1 are much better than the SM I used before so they will stay

Welcome to teflon sound RIAA

I am using the initial 48dB (28v) version with 33r as source resistors.

In this build I have the RC filter on the second stage and on the buffer.

It is "burning" nicely and sounds better every time.

Thank you for your suggestion and sampling work.

If you use (like I use) a Vishay 1280G trimmer, you can adjust the gain in each channel.
