There's no need for the Jisbos on the SOHA II. The output is already a discrete topology. The opamps serve as servo circuits to zero out the voltage offset without having to use output coupling caps.

Oh,Then I stand corrected.

 

Thanks TOMB

Nope, the opamp is only there for feedback, not the signal itself.

Hello,

 

I'm the happy owner of a SOHA II amp (kit bought at www.glassjaraudio.com). I decided last week to print and archive all information about my amp, from http://www.cavalliaudio.com. And I was too late... Disaster ! There is still a web page, but there are not anymore the schematics, BOM, initial start-up sequence, the board drawings... All those precious information needed for the maintenance of the amp.

 

I sent a message on the website to know if it was possible to get those information for maintenance purpose, but I had no answer.

 

Would somebody have archived those precious information and agree to share them ?

 

I especially need them to tune some bias. My amp seems to drift, and it seems to be the reason for e12 spurious triggers.

 

I really hope someone will be able to help.

 

Best regards,

 

JM
