is possible to convert it in Line Mixer and how ?

Thanks

Thanks Drgonzonm

I was asking about something to do as to preserve the original circuit

I'm asking about a mod as to be able to adequate the existing circuit to higher level signal (if doable)

Thanks Again

Clip one end of the 200uFd emitter caps.

Preamp gain drops from almost-100 to almost-1.

However drgonzonm has a point. A line level mixer often does not need any preamp, and going from input jack to mix-pot may be cleaner. Since the mix-bus pots are "inverted" (input at wiper, bus on the top), you need 5K or 10K between input and pot wiper.

Many thanks PRR

you need 5K or 10K between input and pot wiper

this 5-10k resistor is in place of the AC107 circuit, is that correct ?
