A difficult question for experienced DIYers
I've been given an old mixing console, probably a DIY one. But I've got nothing about it: no schematic, not even its date of manufacture.
But the manufacture is really clean and components seems to be quiet good: big toroidal transfomers, SSM components, NE5534 , NE5532, ...
So I think the design may have been taken from a well known console (not sure but why not).
I took a preamp from this console and here is a description:
- 7 log pots. Probably gain / EQ / volume / ...
- 2 diodes : one red and one green
Now the most important part:
- active components are one SSM2016, one SSM2120, one NE5532AN, one TL072CP, one NE5534P and a few discretes transistors
- passive components are 5% resistors and few caps.
- the preamp board is powered by +15 / - 15 VDC
So finally here are my 2 questions:
- does anyone got the datasheet of the active components, more particulary the SSM2016 because I still haven't found its datasheet.
- the hardest question: does these components reminds you of a known design ? (SSL, Neve, ...) Or nothing at all, just DIY ?
Good luck and thank you.
I'll post a few photos in a moment. Myabe they will help you.
