Well...that sounds bad...
Ordered a second Tube Phonopreamp to see if its good or better that my Douk T3plus.
Well... its not.. 😆
Its humming, it sounds thin and flat. Never thougt that it can be that bad in 2026.
However, will give it 100 hours to burn in and test again. But i think its a bad thing.
Meanwhile im waiting for some matched pairs of NOS sovjet 6ZH1P-EV with OTK7 and OTK9 sorting. They are the replacement for the 6A2 / 5654 tubes in my T3plus and the U10 Headphone-amp.
They would fit for the shitty Phonopre too, but i think that he have basically issues in circuitlayout.
