Sound Workshop 1280b - Fully discrete? Transformers? Inductors? DOA?

[jdurango]

An exhaustive search has yielded nothing:

Sound Workshop 1280B console:

- Do all of them have the Beyer input transformers? Just the super EQ versions? Do they have output xformers?
- Are the super EQ's IC based or inductor?
- Preamps, IC or DOA?

Bonus question: any cool mods that can be done on these? Thanks fellas!

All IC opamps.  No inductors IIRC, and I don't recall what mic transformers they used.

1280A had Unbalanced Mic Inputs with No Transformers
1280B had Balaanced Mic Inputs with Input Transformers
all outputs and tape inputs are unbalanced.
There is no Power Fuse, and no Grounded IEC 3 prong outlet.
The 1280 was essentially a Consumer level mixer...
