Hi Atzen,
I have four chassis available from an old project a few years ago that might be of interest.
I was building the Pass/Thagard A75 Class A solid state amps in monoblock versions. I have a set of detailed design drawings that I can FAX to you. The chassis are substantially strong to carry the heavy weight and look very professional like those of KRELL or Threshold. These were custom manufactured for me to my specs by a professional electronics enclosure fab shop in Toronto.
Brief description:
a) Ventilated "U" shaped chassis formed from 12 gauge steel (0.109" thk)measuring 10"W, 20"D and 8"H. Sides are drilled for mounting heatsinks and for wiring of output devices.
b) Ventilated top cover (3 rows of slots, 1/8" X 1" long at 1/4" centers made from 12 gauge steel. Appearance is similar to those on Krell "S" series amplifiers.
c) 12 gauge steel rear panel with cutouts for two 5-Way binding posts for bi-wiring of speakers, 3-pin XLR female balanced input connector, RCA input connector, two fuse holders and (20 A I think)IEC detachable line cord.
d) All steel enclosure parts are cleaned and painted with textured (spatter)satin black enamel.
e) Front panel 19" W X 8-3/4" H X 3/8" thk aluminum (Not yet anodized or machined)
f) Two heavy duty rack handles sculptured from 1" X 1-1/2" alumium bar (Also unfinished, looks like old Threshold)
Let me know if interested.
Regards and good luck.
