What do you think replacing the chassis on MC-XXX amps with third party reproductions does to the value?
Yes...... but stainless philipshead screws, nuts and washers are a better choice unless you are going to be anal about a refurb. In that case, rivets are the only way to go.They are not fun to replace need a special tool to replace all the rivets around the tube sockets.
I just measured an original chassis and a reproduction chassis. The original measures .05120" (1.30048mm) and the reproduction .05085" (1.2959mm). Measuring a few spots those numbers varied by about +/- .0002". The MC225 also has an internal support rib that runs the length of the chassis and the bottom cover also provides support to the chassis top the length of the chassis on each side. Of the couple of dozen chassis sold, there hasn't been any mention of the thickness being an issue. bergui45, I am willing to send you a chassis at my expense for you to take a look at. If you like it you can pay me for it, if you don't like it you can return it at my expense...!! Let me know through a pm or email what your address is if you want me to send it.

I rivet a chassis using a combination of hand riveting and a hand clincher. Depends on where on the chassis the rivet is going.
Well for me the question is first how to remove the rivets?
using a small hand drilling machine to dig a hole in the head of the rivet?
Another question:
is it hard to remove the old chassis before replacing with the new one?
