I'm sure this has been done many times by users here.

I'm in the experimenting phase and my interest here is not to include a presence control but simply add the feedback resistor and shunt resistor to the appropriate point on the LTPPI with feedback taken from the 8ohm secondary tap. If it was just a TMB circuit then I'm pretty sure I know what to do (courtesy of Merlins book). However, the normal channel feeds into this as well, and that has me a scratching my head. Has anyone created a schematic for this?

Thanks in advance ...Dave
