Aluminum Chassis can it be grounded like a steel chassis?

    I am considering getting an aluminum chassis but I am wondering if you can ground to it with a solder lug and screw or bolt? is there anything special needed to do a chassis ground?

    Should be no problem. If it's coated, oxidized from age or anodized you may want to abrade the surface at the lug for good contact.

    I prefer aluminum and some have claimed that the same circuit sounds different in aluminum because of a claimed faster path to ground caused by aluminum being a better conductor than steel. Can't confirm any sound difference.
    Early Marshalls all had aluminum chassis, but one concern is the weaker material may sag from the weight of the transformers.
    I had to add a brace to one of my old Marshalls where the lay down PT had bent the chassis.
    Carr uses aluminum chassis, you can buy almost any hobby chassis in both aluminum and steel.

    It is a good idea to use a stainless steel toothed washer under the nut. You get in trouble mixing metal types as corrosion can be an issue. SS and tinned parts help.

    If you really want the best you need a solid copper chassis.
    Tone of the gods though requires a sterling silver chassis.

    Silver is an even better conductor.

    Indeed - I do this on all my DIY amps, all of them using aluminium chassis. No issue, never. ;)

    No. Use platinum. Very affordable compared to aluminium. :D

    I prefer titanium to ensure it is roadworthy.

    According to the chart I linked above, silver is the best, mercury is the worst. I can attest to that - very messy, hard to drill, and it just makes me so EFFING MAD!

    Mercury is underrated. Used to be in thermostats and float switches and the stuff just kept on working. Then do-gooders that want to keep us healthy got in the act. Now just find a mercury chassis at a good price.

    Made a LP bridge from a bit of titanium. Wow do the sparks glow brightly and the big ones nearly set my shed on fire.

    From this I conclude titanium is the best DIY material for all purposes. Good luck with the chassis!

    Mozart was a way better conductor than Phil Silvers
