I recently acquired a pair of Neotek theater channels but I cannot find what exact model they are and the correct pin outs for them. I've gone on the analogbros mailing list with no luck and emailed Mike at Neotek and haven't gotten a response. I have a couple schematics but they do not match mine completely. These strips have 35 molex pins and the PCB says Neotek 28-03. From what I have gathered I think I have figured out some of it, but I do not know where the send/return is to bridge and the direct out and am not 100% sure on the -/+18v. These have TL074 op amps. Here are a few photos:

This is what I've somewhat gathered from the generic schematic pages-
1. +48
2 - 10. Buss/Routing
11. -18v
12. -18v
13. +18v
14. +18v
15. GND
16. GND
?????
34. Fader Send
35. Fader Return
The rest after that I am not so sure about. I would appreciate any insight into this, thanks!
