Congrats. My first Mac amp was the 2105, new in the early 70's. The Mac Rack (2105/C28/MR77) was hypnotizing at night, sound was fantastic.
Somewhere along the line some people got the idea that the 2105 put out 105 watts and the 2100 only 100. Don't know where those extra 5 came from, maybe the glass? :-)
They were both rated at 100 wpc but actually put out around 150. The first 3 generations of SS Mac used a 5 at the end of the model # to indicate it had glass and meters. I think it was nice that they offered the same amp at a much lower cost if you didn't want the fancy trimmings. Enjoy your classic.
