The issue is that I added a Behringer electronic crossover and the crossover has made it a little too bright and possibly a tinge harsh on the highs.
I read where someone changes out ONLY the center valve on the driver stage board because he feels that is where you can make the most noticable differences.
My goal is to keep the frequency response at the original full bandwith of
Frequency response . . . . 10 Hz to 30 KHz +/- .1 dB at 1 watt
Power bandwidth . . . . … 17 Hz to 30 KHz +/- .3 dB at 60 watts
Is there a tube you can recommend that will make the amp sound as if the Behringer active crossover was not there. I love the way it sounds without the active crossover but i need the active crossover for my configuration.
