I built a Triode Electronics ST-70 Kit for my friend on Saturday.
He wanted the stainless steel chassis, and I wanted something
quick and easy, all in one box. Triode did a nice job of packing
everything tightly in a small, heavy carton. I did the mechanical
work first, then put the circuit boards together, and then wired it
all up. I'd say it took about 4 hours. It biased right up and
sounds great.
