Had to make some changes. Which version is better now? The one with "Gain" or without? Attachments:

I like channel one channel two. Let's me know for certain the one I would go to for left/right.. you know..Other than left side right side.. it could get confusing from the backside input section?

Channel One and Two. Just looks better. You know it's gain. It's got numbers.

Another vote for no gain.

Also prefer without. Less clutter is good.

Dumb question: why not center the controls vertically on the panel?

You typically leave more frame at the bottom, elements higher. I'm looking around at my racks of stuff, there's a mix of everything from centered, weighted higher, weighted lower. Seems to be no standard.

The main reason for not centering is because there is no extra room to move the stepped gain attenuators down. There's a big PIO 2.2uf capacitor in the way. (But I'm gonna stick with the photo framing artistic answer!) Here is the design I finalized with actual RAL colors. Dan Duerloo is working his magic on making it a reality.  |

Probably way too late to the party, but if those 1/4" inputs were significantly lower (is there anything in the way there that would prevent you from lowering them?) not only would the percieved weight of the framing be lowered, but it occurs to me that you don't want to be hitting the cables when you're reaching for the knobs. I think low and out of the way might be both aesthetically and ergonomically better.

Oh yeah, ACTUAL MECHANICAL REASONS! Trumps everything.

There's no room to move the 1/4" jack down. It's all squeezed in pretty close.

Maybe you'll find this helpful. This is a two channel tube mic preamp using an Ian Thompson pcb. Its chock full of 6922 tubes, cinemag input transformers and carnhill output transformers. It took me awhile to design the front panel and switches but in the end i like how it came out. This is also one of my favorite mic preamps albeit one channel can get noisey depending on mic and source. Need to fix that, otherwise its good.  |

Nice looking preamp! I bet that sounds huge with that combination of transformers.

That explains that mystery. Sometimes you just have to make it work!  Congrats on making your creation a reality. Brad |
