    Howdy folks so I've got 2 questions.

    1. I was curious to hear if anybody knows the flat settings for the Acoustic b600 head? I assume everything at 12 o'clock is not the answer. Maybe I should question Acoustic directly?

    2. I have bought this Crate amp I think around february for pretty cheap. Only hassle with it was that you had to flip the power switch a few times to get it to turn on. That being said, it worked like a charm and has a biamp feature which I was looking forward too. Maybe a week or 2 after I brought this home, and after some inactivity, I went to turn the thing on and I got nothin out of it. Totally dead. This being a hybrid amp, could the tube need replacing or amI lookin at something else hear?

    On amp #2, sounds like a faulty switch. One thing about the Bi-amp need a second poweramp. Its funky how it works. It sends the lows I think thru the Crate and then you get another amp for the highs. the chorus will also work in this bi-amp mode.

    yea I figured if i can get this thing up and running i'd have hte crate do the lows with the cutoff at 100hz and my acoustic everything else I suppose. Don't know how i'd hook it up though..

    And a faulty switch heh? Would I be able to remedy this myself or should I bring it to a professional do you think?

    I would first do a tube swap, but the switch really needs to be addressed, if you haven't had any experience dealing with electronic repair, let a tech deal with it, he/they may have a parts source that you may not have access to ... trying to get parts from Loud for old Crate/Ampeg stuff is somewhat iffy now adays ..... IMHO

    this is the response I got from Acoustic about what the flat EQ is for their b600h.

    "Thank you for your recent inquiry.

    Unfortunately, we cannot send that information. I sincerely apologize for the inconvenience.

    I would see to the switch first. I've not seen the amp so I'm unfamiliar with what switch it has. That said switches tend to be somewhat standard. If it's a toggle then they are available almost anywhere. If it's a rocker it's probably a press fit that can be eased out by working the snaps inside the chassis. Then you'll have to source a replacement of the right size from an electronics supply house. If you feel that this is beyond your abilities a tech is your next step.
