Hey Zep, I checked out the schematics on the Jr.& the Deluxe, Fender still uses two different power transformers, I guess that explains the high conversion price, but the good news is you can go the route Lordathestrings posted, I played for 1&1/2 years on a step down transformer, and had no problems, Have fun in Chicago, I lived there for a year, and as far as I'm concerned it is America's best big city..
