A little premature, on my part. I am missing a couple of components so haven't powered it up but here are some chassis efforts.

I see two knobs, did you use two volume pots instead of a single dual pot?

I didn't think of that, it would have the added feature of balance control.

yes, they are Alps mono pots. There was discussion on the B1 main thread about the use of stereo or mono and gain control so I thought I'd use two monos.

Anyone have any experience with very heavy bass output in the B1? I am running a 50k blue velvet as my volume pot and stuck with the values NP gave in the article....his board btw... and the bass is overpowering. Everything else seems to sound fine. It has at least twice the bass as my BOZ. Which I consider to my "neutral" reference right now. It replaced my YBA 3 preamp. Any thoughts as to why I have so much stinking bass?

B1 builders thread
Is it possible your previous preamp had an early rolloff when coupled to your amp, for low freq's and the B1 when coupled to your amp is essentially flat down to a much lower freq? It could be you have too much baffle step compensation in your speakers (or they are close to walls/corners) and the previous preamp was rolling off early and compensating for this, but the B1 is not, so it now stands out.... If you have a way of doing freq response measurements of the whole chain (eg using truerta) This could give you the answer.

Tony.
