It's a mean engineering feat. This guy has spent a lot of time and energy to design this amp, that's very applaudable :smt038 :smt038
From my personal point of view, although I really admire his engineering capability, there are quite a few drawbacks with his design.
1) The circuit is crammed tight together, although there is a external fan to exhaust heat, but the fan is a mechnical device, with limited lifespan. While people tend to want their amp to last 10yrs or more.
2) Looks like a double sided PCB style of construction. Good design is very important as using this method tend to be condusive for noise & hum pickup.
3) The way this thing is built, it seems like a one-way construction. Which means, in future when it break down, you'll need to dismantle a lot of wiring to access the components. In the process, could damage more components.
4) As vern put it, this guy used a number of hard to get/non commercial components. Even the tube used is not available outside.
5) Price wise, is in the boutique range. So other than a novelty item, with spare cash to spend, not a feasible 'amp', as usage is even more limited than a vintage fender champ.
Well, like they say, you can do what you like with your own cash, as long as you really like/love it, why not.
