I'll second wolf_garcia's and other's comments about the Maryland-based Jolida. Had a Jolida 502B for a decade. My intro to tubes. Good value for the money. The factory upgrade for it was another high value bargain. It responded readily to tube rolling. It's well within your budget. I liked the fact that biasing was manual (and easy to do, I might add). Only reason I stopped using it was I needed more power for some lower efficiency speakers. Good luck in your search.
