I own a near mint MK II C ( NOT C+)
I have been trying to find a good schematic for the plain ole II C for YEARS.

Does anyone out there know where I can find a schematic for the II C ?

There are zillions of IIC+ schematics on the NET for the IIC+ but NONE ( that I can find ) for the IIC.
Hard to believe that Mesa manufactured over 1000 IIC and there is no schematic ??

Also would love to find good documentation/ drawings /schematic and notes on the famous Mike B conversion from IIC to IIC+

Any replies/ comments /info greatly appreciated !

No official one out there supposedly but chipaudette traced theirs:

They then traced the follow up when Mike B upgraded it to IIC+

The IIC schematic for the RP11 is the best I can get it without tracing one first hand. Looks like there is some weird stuff going on with the Lead Pull Bright as opposed to the RP10 board, but is very similar to the RP10 apart from that. It also has all of the EQ, automatic treble shift, V2A/B rearranged and power section already at IIC+ specs. Like it was designed with the + upgrade in mind unlike the RP10 board...
