The only way I can think of is to use a power regenerator like the PP-300 from PS Audio or the SDS from Vpi. Both of them cost about $1000 new or $600 used. Don't know if that meet your definition of economic way.

Since you mentioned that you just moved FROM Europe, wouldnt you want to keep your table 60Hz. I just recently swaped a 50Hz crystal on a Linn Valhalla ps for a 60Hz and it cost me about $3.00. If your ps has a crystal, perhaps you could do this also. Be specific on your current ps. Is it 50 or 60Hz?
CLEARAUDIO got a device available for that conversion. It can convert both 110/220 and frequency tune between 40-100Hz. But quite expensive as sold in Hong Kong for about HK$6500. I think I met the same problem for moving my SYSTEMDEK from Hong Kong to Canada. Dont know whether it works at 110V 60Hz at the right speed or not!
