replacement part for Trace Acoustic amp

[guitargus]

I need to replace "pre amp pack c741 hybrid" on a Trace Acoustic TA 100R. Itīs the operational at the preamp section, that cames sealed. Where can I find it?

I am looking at the TA100R schematic, and I do not see any odd part in the preamp. What does it connect to directly?

In the power amp there is a DC2 - Dynamic Correction Module. Pin 2 of that is connected to the speaker return as a feedback.

Enzo,
thanks for your answer!
My tech explained to me that he needs to replace all the module because itīs sealed. The failure consists of "spikes" once in a while, caused by a damaged current filter.
