I was fiddling with the gain setting on my Little Dot I+, and it occurred to me that the op-amp was running pretty warm, perhaps warmer than typical for solid states, and that I'd seen people running metal op-amps with heatsinks.
I had a plastic-shelled op-amp, which isn't conducive to heat conductance, and I lacked a true heatsink with a planar base and flanges to dissipate heat, but such thermodynamic limitations would not stop me! Seeing as the op-amp (MC33078n) is unmitigated trash anyway, I glued two small nails to it.
It sounds the same, though maybe a bit less strained--probably placebo. Nothing will change the fact that it's like listening to a hifi-stereo system wrapped in a memory foam mattress, though. Can't wait to hear the tubes with a better op-amp....
So...the moral of the story? If you want your amp to look stupid inside, and sound basically the same, glue nails to the op-amps I guess?
