Posisible?

Yes, you can.

I'd suggest that you consider the warranty...if it's under warranty, installing the bias pot will void the warranty. If it's not under warranty, make sure the work is done by a reputable tech (or yourself) being "in the know" of how to do the conversion....the output section of these amps are a bit different from the "norm" and can be a costly venture if the work is done incorrectly.

Good luck and let us know how it works out if you get the changeover!
