I did notice that! I've never built an amp before, just worked on existing ones that run much cooler, so not sure how a ventilated case works out vs. a more closed one with chunky heat sinks, especially on an amp that puts out so much heat. My question was related to reliability, not aesthetics or build quality. I like the build! This last question is more out of curiosity and not so important but I can't really tell what the volume knob looks like in the pic of the front face of the Korg Nutube preamp--insufficient image resolution. Can you snap another pic of that? Re: the preamp, also wondering if it you could confirm that it would be easy to rewire the second input to be a second output or if I'd have to figure out another solution to send a second signal to my other amp to power the swarm subs. Seems like I could easily do this but wanted to make sure.
