Consonance Opera Cyber 211 mods

I have the Cyber 211s driving Kharma CRMs fe 3.2 and really like them, especially after replacing the stock tubes with the psvanes and using the bpt power supply. I am now ready to tackle the parts upgrade, as there are several blogs out there signing the praises of the vcap cu in the signal path.

I am hoping some one out there has some experience doing that along with changing out resisters, perhaps the diodes, and whatever else, like ps caps and adding bypass caps, internal wiring (likely litz flavored) etc.,

I am looking for a recommended parts list.

I am game to do the r and r myself, but if you can recommend someone in the San Francisco area, please do.

Thank you for the help.

My Opera Consonance cyber 211 was broken when my Wife let the wire become unpluged.  We have replaced a transform sent by consonance.  but we can not get the Bias to 4.8 it stops at 0.8 and the screw does not advance it.  Does anyone have a diagram of this amp.  Any advice as to what most likely failed??

 

This is a wonderful amp but my adventure in fixing it has taken the most part of a year.  David Mann 239-404-5265
