Can the power supply be built in the same box as the two amps?
Yes, and this is recommended. The amp is utterly quiet built this way, with the Star Earth configuration implemented on the custom printed circuit board we supply as an option. The design of power supply we recommend can be found on the web pages and in the accompanying kitset documentation. Physical layout is uncritical. We can supply diodes, filter capacitors and a custom printed circuit board; but not the transformers, because of cost, weight, shipping and space considerations. In most countries it is very easy to obtain a suitable transformer, and extensive recommendations of suitable toroidal transformers are made in the documentation.
