I like to tinker, but I'm pretty much ignorant of things electronic. But, like most people, I won't let my own ignorance stand in my way.
I'm going to have a look at the Kama Bay Amp, now the 1100, for little things I can do to tweak it. Of course, new caps and wire are first up. That's about the limit of my abilities, electronic, soldering and otherwise.
I'll see what I can do with it and report as I go... if I don't forget.
