1073 1084 with EQ DIY project HELP THREAD

[loopermc5]

I got my first channel going I notice when I switch in the eq though I get a volume boost it also sounds a little more bassy or major h.f roll off is this normal I have never heard a 1084 plus I don't have anything to test it a scope and such.Sounds really really good so far

Thanks

Is there any interest in good concentric switches for the 1073 and 1084? Not shooting for originals here, just elma through the whole thing like B.A's remakes and probably Omeg or Bourne's pot coupled to the shafts?

Been digging for information lately and since the concentric stuff is considered custom for Elma it places minimums up there.

04's for gain, 01 for switches except on the 1084 we swap a 01 to a 04. Still working on numbers and it won't happen for about 2-3 months, possibly the first of 09.

These wont work for the 1081 and vise versa, do some homework before asking.
