McIntosh MC7205 Amplifiers

For those that say these are Japanese amps with a McIntosh label slapped on them I suggest you visit the Mcintosh factory in Binghamton NY yourself where you can watch your amp being build by hand.

I owned this amp for almost a year and it worked fine until one night while playing at low levels, the amp started smoking.

my question is what are the main differences b/t the mc7205 & mc205. as well i am using this amp with an mx-135 and plan to purchase a vintage mcintosh tube amp to run my front mains basically for music listening.
