In Reply to: Aluminum plate thickness for amp project posted by rogerh113 on June 4, 2015 at 06:30:42:
For transformers that heavy, I use 6061 plate at least 0.188" thick (I prefer 0.250"). Working a plate that thick requires special tools, but I have a small CNC mill for this. If you're short on tools, I would strongly recommend going to a company like Front Panel Express. I think their products are more limited in terms of thickness, but really, 3mm - 4mm will get the job done. For mounting items like tube sockets from underneath, you can have FPE mill a recess in the underside. The recess can be round, say 2.00" - 2.25", and if you leave a thickness of .040" or .050" in that area, overall panel strength will still be very good.
