<b>visitorj</b>, can you make a photo of the IC and the board please ? and the schema if you have it?

I got some of my Dutch R2R friends to have a look at it as well and with a bit of luck they can design a circuit with disrete components.& E8 g* i: Z& X& }" Z
This will help all Sony R2R users in the near future as well as our machines age over time.
