Look for Vintage Lafayette KT-550, HK Citation II and Dynaco MK III (7027a, 6550, and 6550) These out output at least 60 Watts to 70 Watts or tube power. If you have more $$$, Mac MC275 is also another high power stuff.
For modern amp, you can look for Music Reference RM-9 but the tubes will cost you a bundle.
