Hello Andreas,
I have my own drawn schematic of the MK-II version.
This means the limiters and drivers are no longer ceramic boards.
These gave many problems.
But the MK-I and MK-II schematics are the same.
When I'm at home I will sent you this schematic.
I'm new here on this forum. I I can help somebody else
with this schematis I will post it here.
Greetings, Roland Huisman
I guess, that only the schematic topology between MK-I version and MK-II version is the same. But the values of the discrete devices on the ceramic carrier board-module is different. Befor I make new developement, I want to test the MK-II modules.
Where I can get the newer driver modules ?
Thanks to provide!!!!!!!!!!! Thank you very much!
any news?

Not included are the original Hybrid card schematics listing the IC types, Roland has them listed as TL072, can anybody confirm these are the right ones, ie not ne5532?
