Building A Stereo Tube Amp

Step 6 The Build: Getting Started

So I put the power supply on one side and the audio circuit on another. On the inside of the case, I attached a copper-coated plate that would serve to ground anything connected to it. This makes it easy to ground the exteriors of the transformers and hopefully reduce some hum. The transformers aare firmly connected to the plate with nut and bolts, and so fix the plate itself to the inside of the case.
