So I have a brand new DSL100HR-U head and MX412a cab. when on the clean channel  the proverbial wind noise comes threw. all mu other amp cab setups are working fine with the MX412a and it is not the cab. Everything from power conditioner to the cables are new as well. the only thing i havent  done is swwitching out valves. Any thoughts or advice? Also to mention I'm a blind musician. and firstish timer amp troubleshooter
