Audio Systems: switching a 20 watt amp to a 60 watt amp..., 4 ohms, watt amp

Question
I would like to turn my 20 watt Crate DSP guitar amp into a 60 watter by switching the power supplies/transformers out from my blown G60XL's head (and obviously switching the speakers out)? Both speakers are rated at 4 ohms.  Will this turn the output from 20 to 60 watts? Please advise...

Answer
I may have been rude from your perspective but it is obvious that you haven't a clue what your doing. because if you did you would not ask a  question like that to begin with. I can't advise you to do something that is outside the realm of possibility. If you don't believe me try asking another professional. If he tells you how to do it then I welcome your slap in the face by giving me a negative response, otherwise it will be you who has given yourself that response. I've been doing this for 37 years. How long are you doing it?
