Hi everybody,
I’ve just bought three sclumberger preamps TAM 628 and they sound great, full vintage French tv stuff.

I would like to increase gain, maximum for now is 34db, not so bad but sometimes i should need more gain.
Here is the schematic of the beast.
I would be gratefull if anyone could help me.
Many thanks for your attention,
Louis.
