Abstinence makes the fart grow stronger?

Anyway, yeah, building a one-off amp from a recipe is only the first step! There will always be tweaking after the build is completed, whether to meet the tastes of the builder or the client.

I got a good laugh because some of their photos are clearly off-the-shelf fuses with colorful stickers wrapped around them. Nice markup!

Nice work!

No interaction at all, in my experience.

Phil, just look at the zillions (ok, hundreds) of stereo amp chassis for home stereos of the 60s.
