Can balance knob be bypassed

[Finkle]

Live in the mix! Functional, sweet sounding preamp is back! Was a lot of changes at once, output cap change happened, also heavy duty on/off switch too. Been listening without it for 3 to 4 weeks. Immediately could tell it's going to be a lot of fun having it back. Engaging. Completely black at very high levels when music goes quiet, not that it wasn't before, just probably a good sign?!

A few things I think the next iteration could end up with: using the same red & black wire as sent with the kit, parts express wire coating is minimal. Probably add an on light. Not sure what chassis changes yet but probably stay the same external dimensions, finish the base. Reposition RCA jacks and iec power cord to the back.

Thanks again guys! Rockstars!

I'm digging up an old post but I feel it is relevant here.

I plan on buying the upgrade as soon as it is available for the improved power supply, but in the mean time I have a 10K, 24 step volume attenuator that I would like to test out with the balance pot bypassed.

Earlier in the thread, Paul said  "The easy way is to remove each red wire leaving the balance pot from each of the center lugs.  The red wire that left the top deck can be moved to the balance pot terminal with the white wire, and the red wire that left the bottom deck can be moved to the balance pot terminal with the red wire.

Is this in addition to adding the 100K resistors between the red and black wires at the sockets (in other words do I still attach the resistors between A6 and T2 ........B6 to T12?

Thank you! Greg

If you just move the wires on the balance pot, then it turns the balance pot into a pair of resistors so there's a ground reference for the input.  You'll want to leave the balance control somewhere close to the center still if you do this, but the effect of turning the balance pot all the way one way or the other will potentially be inaudible.

Perfect. Thank you Paul!
