Your effort looks very nice.

How hard are you going to use it?

Adcom had good success with their 60W rated 535 and 100W rated 545. They used the same circuit board for both models, just more heatsink and more outputs. The 535 had a 3.5" tall heatsink and two pair of plastic outputs. The 545 had a 5.25" tall heatsink and three pair of plastic outputs.

The 200W rated 555 went to four pair of metal cased outputs with 7" tall heatsinks.
