Altec 1588B Mic Pre Module High Gain MOD

[tablebeast]

Someone mentioned the Altec 1588B modules. If you recap them there are no noise issues, its a very clean pre amp under normal gain settings, but gets wonderfully hairy when you drive it. I find it to be an incredible pre on rock drums, I can color each to taste. Anyway, the mod to give the 1588B module enough gain to stand alone and have a direct output pulled from all these altec mixers (1592A and B, 1599A and B, modular 1581A, etc) is fairly simple, plus while you have the shell off the module you can go ahead and swap out the electrolytic caps. Here are the pics describing the mod.
