Restek Preamp ...
 

Hi all

Does anyone by any chance have any documentation on an early Restek unit
called
" Thorens-Restek Preamplifier V3 ". I'm particularly interested in the DIP
switch settings for the phono sub-board that plugs in inside it, and the
actual phono sensitivity specs for MC / MM options which I believe are
selectable by the DIP switches.

If anyone had any schematics for it, this would be extra helpful. I'm pretty
sure that I've managed to correctly derive the phono board's schematic from
reverse engineering the print layout, but it would be useful to be able to
confirm it.

Incidentally, I did try looking on Restek's website, but this model does not
appear, even in the ' vintage archive '. I tried e-mailing them, but no
response.

TIA
