Running a 220v preamp on a 110v line?

I bought a used CJ preamp which is configured for 220v, yet it has standard 3 prong U.S. type plug. Can I plug this into standard 110v outlet? What will happen? Will a step-up transformer degrade the sound?
Don´t do it. You need two 110 volt lines to feed the parallel plug terminals. Either you put a new 110 volt line or take power out of the dryer circuit if you have it which runs at 220 volts.
Hire an electrician to do what I suggested. Good Luck
What will happen? Your preamp will not last a second.
C-J will change the voltage for 96USD plus postage. A step up transformer will degrade quality.
