Even great Papa can't send electrons jumping thru quantum space on boards yet.
Always best to use meter and find out for yourself, helps familiarize your self with circuit and impresses friends

Four Channel B1
Recently I have become a big fan of active crossovers and have been using a ganged pot after a modded Behringer DCX (crossover) and prior to 4 channels of amplification.
I saw reference to the B2 buffer, but I guess that is not being released for DIY. So I made a breadboard version of the B1 buffer (2 channel version at this point).
So currently the power supply on the B1 buffer drives two channels and it uses a power adapter from an old HP printer (18volt and 1.1 amp). I read that the B1 circuit only draws about 20 mA.
I would like to use the current Power Supply section from the B1 and have it run a total of 4 channels. My plan is simply to use the current Power Supply section and have it drive the additional circuitry for the extra channels. Although I might increase the R1 resistor from 3W to 5W.
I guess my question is whether a single B1 power supply is sufficient to drive the extra channels?
Again, I am pleased with the sound of my 2 channel B1 buffer (with the "stock" power supply). I am happy with the power supply as it is.
Cheers!
