a general question: Are metal enclosures better for protecting against emi noise? Plastic enclosures definitely look cool.

Yes, and aluminum is better than steel as it does not conduct magnetic flux.

How about a separate chassis for the transformers, made of wood or aluminum. Everything else inside or on plastic. That way the weight of the transformers is not a problem. There are some very high-end amps that put the xfrms on a separate support, not because of the weight, but to keep xfrmr vibration away from tubes.

Post subject:  cut plastic chassis

I have clear plastic chassis and need to cut to box my t-amp.

I have a circular saw for cutting plywood, will this work?, drilling? any hints will be appreciated.

Hi gychang, welcome to the forum.

The teeth on a circular saw are likely too coarse. You will want to use something with fine teeth like a hacksaw, bandsaw or even a jigsaw can work.

I was okay cutting Lexan with circular saw. Then you can sand it down but the sanding takes a while cuz you cant go fast or it gets hot and when its hot it just fills the sandpaper with smeared plastic. I dont know what plastic you are using so it may not apply. I also should mention it was nearly a half inch thick and I think that something 1/8" thick may have splintered.
