Adding an input to the B-1

[westend]

Can I successfully and elegantly add a third input to an original B-1 build? Also, is an additional output simply a matter of paralleling the stock output? The second output would be used for a subwoofer amplifier. I realize a switch change would be needed to accommodate a third input but beyond that I am clueless as to connections and fear an imbalancing of the circuit.
Any help appreciated.

just switch for input

yup , output parallel , under condition that additional power amp is having harmless Rin

say 22K an up

Thanks, ZM.
I am repurposing the buffer for an audio friend that needs the modifications. I believe I'll switch the outputs, too- Amp1, Amp2, Amp 1&2.

Also feasible.. Get the kit in ebay or here.

Stepped attenuator + switch digital. They are fine
