Thanks for all the responses. Unfortunately I do not have the ability to put in a dedicated 240 line. I also discovered that the transformer I was given by the manufacturer of the amp to "solve my problem" apparently is quite inexpensive...less than $50. The more I read the above responses the more I feel that I have been put in a rather untenable position by the mfg. - sending the amp back to the mfg. to "re-wire" the amp will cost hundreds of $. To clarify, it was never agreed to when I bought the amp that it would not work on 110 volt power without using a transformer. I guess this is why buying product over a long distance is so risky.
Finally, the mfg swears that the transformer makes no difference in the sound of the amplifier. I seem to hear some high end hash from the amp which may be a function of the cables, but the high frequencies are beginning to, more and more, grate on my ears.
