Paul of Reference Fidelity Components has commissioned me to build him an STA25! Clearly a man of exquisite taste in amplification

I thought it would be nice to document the process of building it to showcase the parts used and effort taken.

I didn't start taking photos from the very beginning but the amp starts out as a chassis surround, and I begin bolting various bits on. The transformers and most of the amp circuitry sit on a sub chassis made from brush stainless steel.

As you can see the main surround has a few basic bits mounted.


Some of the wiring beneath has been done and the tails come up through grommeted holes ready for the transformers.
