Arrh !

You make 26 as well Felipe !

I looked at this also...
...good with attenuator between Itch & 26 maybe.

Felipe...You told me a year ago...but I forget...
...You are using 'balanced amps'...yes ?
..I think you built yourself Nelson something ( F? ).

What line-stage do you use/build ?
This is what you listen to 'Itch' with now...before amps/s ?

Si.

Hope that makes sense.

( nice grommets !!! )

Nice... so TT GND is connected only to preamp chassis and NOT to circuit gnd.

The chassis itself connects to the circuit MINUS only throu the GND loop breaker circuit....

TT gnd it's only connected to chassis, the gnd coming from separate PSU goes to the ground loop breaker so you have a clean ground star without any ground loop where to connect all grounds, see attached pic.
