same for me, auto on/off works perfectly using RCA 25dB, two PS, original opamps

My (RCA only) tube preamp has a lot of gain. I'd like to reduce the V3 mono gain (<25dB). May I have the schematics? Or can you teach me what to change (resistor at opamp 1)? I have the early model from August 2024. It seems the new revision has lower gain already. What was changed? thanks
