Thanks for your reply and advice. Unfortuneately, due to budget constraints I am seeking out a second hand amp. While this isnt the ideal situation ( I'd obviously like to buy NEW! ), the low shipping weight, and used prices of US Crowns make this my only available choice at present.
Is it possible to have the PS changed to 220V operation by a technician?
I am aware of the service issues, but these are relaiable amps, and if I buy second hand that is simply a risk I must factor in.
