Aluminium is not anodized (yet), and I plan on using a copper screw to ground the earth from the AC outlet to the chassis. I have already tested one half of the amplifier (one ps and one amp) with both the power supply and amplifier floating. There seemed to be a sleight humm, but the improvised audio input wires might have been the culprit for ...
Grounding and Shielding for your DIY Audio Projects
http://diyaudioprojects.com/Technical/Grounding-Shielding/
In a typical piece of audio equipment (most everything else as well) there are usually three distinct ground circuits. The first is obvious, the signal ground, the second is the power supply ground and third and often ignored is the case or chassis ground. Each has a …

In a correctly wired XLR or TRS interconnect cable, the shield is connected directly to the chassis at the connector, not to the audio circuit common. True the audio circuit common is also probably connected to the chassis, but it has a different function. Remember that a balanced interconnect is a two wire circuit. No ground is required. 1
What's the difference between Earth, Signal, and Chassis ...

Describing chassis ground can be confusing because, when speaking about audio equipment, a chassis ground can differ depending on manufacturer. A chassis ground can be connected to the earth ground if it’s meant to prevent electrical shock, or the signal ground when intended for shielding.

The chassis ground point on a vehicle is typically a large, integral stud or bolt close to the battery, and connected directly to the negative battery terminal. The body of the vehicle, therefore, serves as the return path for the entire electrical system of the vehicle as well as a dissipation path for static, RF interference on sound systems ...
Earthing (Grounding) Your Hi-Fi - Tricks and Techniques

The basic idea of an electrical safety earth (or ground) is pretty much the same everywhere, but the details can vary widely. The case (chassis) of the equipment (and except for special situations, the internal electronics) is connected to an earth pin on the mains outlet.

0. caraudio.com. Mar 17, 2008. #4. it depends on how much you know about your car and how much you want to spend. 1) do NOT let anyone tell you that if your ground wire is over 3ft long, its a bad ground. by grounding to the chassis, you have just inadvertently grounded to the battery as well. the chassis acts like a wire and it all leads back ...
Ground rules: earth, chassis, and signal ground
https://www.analogictips.com/faq-ground-rules-earth-chassis-signal-ground-faq/
A chassis ground is a ground-collection point that connects to the metal enclosure of an electrical device. A chassis ground may be used for shielding and grounding to prevent electrical shock. Mains’ earth ground and the (theoretically) 0V power rails are all tied together and connected to the chassis at that one point.

The chassis symbol usually indicates connection to a metal frame such as that of a vehicle or metal case of a piece of equipment such as an amplifier or oscilloscope. When used with the standard GND symbol below it will often appear only once to indicate the point in the circuit where the chassis connection is made. Ground or GND
