    I've been trying to take the chassis of this amp out, so I can hardwire a grounded plug into it, but I can't get the bloody chassis out! I've tried unscrewing everything, but to no success. Please tell me I don't have to unscrew the transformers as well, because that would be a real bitch.

    How do I get this bloody thing open?!? :mad:

    Hi Sean!

    There should be chassis through bolts from underneath. They may be through the srtap handle or through the feet too.
    You may have to take off the front grille and slide it out that way. My 2000s' tranny won't come out the back and had to be done that way.

    remove the Four screw on the bottom of the head box, and the Chassis slides out the back.. After you take off the back panel ofcourse.

    You can't get the chassis out and you're messing with the wiring???

    That amp can still shock the snot out of you even when it's not plugged in. Be careful.

    I decided to just drop it off at an AV repair place, because i'm gonna end up breaking something trying to get it open.

    Also, i've opened up tube amps before. My bassman came apart a LOT easier than this thing.
