Hi all,
I've NadL53 amplifier and I need to get variable line level output from it. This sucker doesn't have it so I was thinking I'll try to modify it (hopefully I get the smoke out and can upgrade to whole thing).
I've attached a circuit drawing of the amp. On left side there's the preamp chip, output from pins 49 and 50 goes to the power amps inputs (on the right side of the picture). What would be the best way to steal the variable signal? Can I just take the signal by connecting the new outputs parallel to amps inputs at the connector CN23? I guess at least series resistors are needed?
I hope that the above made some sense. Please help.
