Hey guys baka merong may alam.
I'm assembling tube amps right now. I recall when I was so much younger (and incapable of such projects back then) there was this company Celco Marketing (CMC) that sold these tough GI chassis boxes which are just right for the project. I can't seem to find them anymore, and right now, I would want to get my hands on those kinds of chassis.
Those things are very tough, unlike those that you can find at deeco. And consequently very difficult to work and drill and stuff.
But now that my mind is set on it, baka merong may alam where I can get those. I don't mean yung mga chassis na nabibili sa Deeco which bend and surely will under the weight of the large transformers I intend to place on them.

Any help would be appreciated.
