Default Vintage Audire Diffet 2 preamp help

I own the preamp in the object which came to me with no user's guide.

While cleaning the boards inside, I've noticed there are two micro switches in the phono board, which is capable to amplify MM/MC cartridges. Are they useful to set different capacitance/impedance loads by any chance?

Will you be so kind as to explain how the four positions work? Anyone who is able to post a scheme or provide the user's guide? Thanks.

This might be similiar to the Poco headamp made by Audire. That one had gain switchable 24/32 db gain and not cap/res loading. I might be wrong on the gain as this goes way back in the time machine memory banks..

Regards
David

I use a Diffet 1A and Diffet 3 and have owned the Legato and Diffet 2. The head amp section is the same as the stand alone POCO. I have an original POCO manual and will email it to you if you send me your email address.
