I, too, would like to thank Bobby B. for his thoughtful replies here. It's appreciated.
More questions:
Are the pots mounted to one of the circuit boards? I've read differing opinions on the implications of doing this. I suspect that they have been so mounted in most of the micros I've owned or just played - don't recall any catastrophic failures because of this (indeed, it seems more likely that something else would go wrong). Still, mounting the pots to the chassis with leads to the board seems a safer bet... Anyway, I'm curious about this.
Slightly off topic: are the stereo and selectable stereo/bridged mono versions of the power section available for purchase? I am nowhere near DIYing an amp - even a simple power amp - just yet, but I've thought about it, and the tiny poweramp has become a popular topic here of late.
Related: Is there a power-amp in? I see them less on amps these days. If not, how "clean"/uncolored is the effects return? Basically, can you use this as a small poweramp, bypassing the EQ and inherent voicing of the amp? I'm not necessarily expecting the amp to have this - most integrated heads I know, don't. It would just be a nice bonus.
Am slightly intrigued by the KOSMOS, even though I don't usually go for onboard effects of any kind - more so, admittedly, after reading that it's all analog.
