Mark Levinson MC Pre-Preamplifier JC-1 (JC1) - how many Versions at whole are there

Until now I know this Versions:
1) JC-1
2) JC-1DC
both made for battery only and for both the schematic I have - go to this threads:
https://www.diyaudio.com/community/...etween-mark-levinsons-jc-1-and-jc-1dc.243267/
www.diyaudio.com/community/threads/mark-levinson-jc-1dc.372134/
https://www.diyaudio.com/community/...rom-mark-levinson-for-jc1-resp-ro-iii.242541/

But in the meantime I have discover further for me unknown versions:
3) JC-1SM (JC1-SM)
4) JC-1DC series two
5) JC-1AC small power supply
6) JC-1AC high current power supply
7) JC-1 with integrated transformer (maybe a clone of one from previous mentioned)

Who have the associated schematics for this versions ?
