Post Brum i Vox
Bytte slutrör i min Vox AC30C2 igår och efteråt har jag ett konstant bakgrundsbrum.
Kommer från högtalarna men går ej att påverka med volumekontrollen.
Inte något som stör vid normalt spel men inget jag märkt tidigare.
Provade att sätta tillbaka de gamla rören men samma brum med dessa.
Testat byta preamprör också men ingen skillnad.
Var göra?

Kör du med "Hot" eller "Warm" bias ? Eller blir det nån skillnad i brum om du switchar ?
