Anyone have a Spectra Sonics 500 schematic or drawings ?

[digitana]

Hi all..my first post.. I have been  googling quite hard for a schematic or reverse engineering drawing of the spectra sonics
passive EQ 500 but with no luck.  I am going to acquire a couple of 110 boards and would like to build a couple of these to maybe go in  a rack alongside the 110's. Any help would be appreciated !

Bump for this schematic....

I have a couple 500's in melcor channel strips;  would love the schematics for them.

Best way to get the schematic would be to contact Richard Guy.

pm me if you need an email

Cool, let us know if you got it.

Did you contact over email or ebay?

when I joined the spectra sonics archive he emailed me ..then I recognised the name after your post.  He said  SS never made available schematics ..but he would try and get a drawing. 

There must have been schematics for all their products ..but they seem to have kept them very close to their chests !
After almost 50 years this seems a bit odd to me  why  these are still being kept under wraps.  Perhaps because it seems the company in some form or other  is still going and selling products based on 101/110, the eq and compressor etc ??

Would have thought any patents have long since lapsed....and I am not sure the 500 series eq ever had patents associated with it ?
