Thanks MIke, I think I know how to handle this now. It's OK for the transformers to be in contact with the chassis if I use trim/holddown parts on the feet. The trim will cover the contact area, so any scratches or impressions in the paint won't show. All I need to do is make sure the trim itself can't mar the paint. BTW, you've given me another idea for the design, but I'll need to mill the parts and trial mount the trim to see if I like the look. I'll post a photo if it's a go.
Being as they're uncoated, the lam bolts should be pretty simple. Surface prep will be straightforward, and epoxy-based black paint should last the life of the transformers (or at least the life of the paint that's already on the endbells). Incidentally, the brass screw heads look dull in the photos, but they really stand out in person. If there was other gold or brass hardware, it might not be a problem. They just look odd to me with everything else being black or silver and with no other hardware showing.
I think this will work out well. I can go ahead and cut the chassis now for the OPTs, then mount them temporarily with through bolts. When other issues are further along, I can replace the bolts with trim pieces. Wow, it'll be a real relief when all of these mechanical and cosmetic design decisions are done. I'd much rather spend my time listening to this superb iron you make!
