Difference Bewteen HD 210 & HD 212

Is there much of a difference between these two amps as far as sound and tone is concerned? I know Claton used the 212's in the 70's...don't know of anyone using the 210 but I love it and have two of them now.
Has anyone used both and what do you think. I play the classic rock circut with some blues and stuff mixed. No complaints...love what I have...but am curious. thanks...would always like to speak with someone in person on this subject...516-889-6895...I live in Long Island...or e mail me your nmber and I can call you.

As long as both chassis are the same vintage (either solid-state or tube phase-splitter circuit) and the same model (65, 75, 130 or 150), then the differences in sound will be speakers and cabinet, as the electronics were identical.

Wondering what model Brian MacLoed of the Headpins used to get his sound on th "TURN IT LOUD" early eighties album. Anyone know? Any help would be greatly appriciated.
Thanks,
