Hi,

I opened up my Creativision MKII (i guess yours is an MKII) an i found, that the internal PSU part is different to an MKI (and so different to the schematic one finds online...)

Using a 3 Wire Transformer (with centertapping) will NOT WORK with a Creativision MKII (not sure about the MKI, as i do not own one anymore...)
as it uses one Wire of the 18V AC as common Ground!!!!!

I made a very crude drawing of the insides of the CVMKII...

Any Electronic Gurus are welcome to comment, as i have no clue, why they built it that way... and if i am right in my opinion/conclusion?????

Greetings, TOM:0)
