Worth the effort Eric imho. I've gone overkill with a Salas 1.1bib supply for the LDR. lovely on female vocals.

Prototype chassis photos
Prototype Store Chassis
Here are some photos of the Prototype store chassis, it's about 98% correct, there's a couple layout issues that will be corrected (move all the holes a bit to the right, move the PCB more towards the center, etc...) but generally this is what it will look like - and I think it looks great!
There will also be a parts kit available, similar to what's shown but not exactly what's seen here. Will be similar or better. 🙂
Timeframe? Soon(ish)

Looks really classy!!! From the picture there looks like there's no feet or even pads providing any separation from the resting surface?
It has the little stick-on feet supplied from HiFi2000.
You can of course change the feet to something you like better. I quite like Vibrapods for this circuit.

Beautiful enclosure! Just finished building mine late last night. What an improvement for my ACAs! And no microphonics, unless I tap directly on the glass. Very, very happy with this (humble) setup. My turn to say thanks to Mr. Pass.

Nice clean lines, and well laid out. Great job Jim, thanks again for working on these projects for us!
A nice and clean designed case for the B1 NUTUBE Preamp!
And available for everybody in the near future.
Very cool little soundmachine!
Cheers

Looks great nice and simple and attractive.
Is there a simple way to reverse the phase of the output to use this as a headphone amp?
I'm not able to just swap the + and - leads over for headphones on my build.
Can anyone suggest a simple inverting buffer circuit that I could use?

Hello avtech23,
this is the question! This is why I didn't put my headphones with inverted polarity
to the B1 NUTUBE.
A headphone jack shares ground on one Pin/ring and + right and + left.are
seperated rings / contacts.
So I would have to slice the cables to the headphone. I do not want to do that.
And you would have to do that on the loudspeaker of the headphone.
Or you have a headphone where + and -/gnd are coming out of each side.
Inverting buffer could be a possibility. but adds another stage. 😕
I also wanted to try this with my STAX. But the adapter is transformer coupled.
And if I invert polarity between B1 NUTUBE preamp output and input poweramp I would send the signal + of the preamp to gnd of the poweramp
and the gnd/- of the preamp to the + of the input of the poweramp.
I don't wanna make a short.

@6l6, any recommendation on remote kit that will work with the chassis kit option posted few posts back?
A remote control? A motorized potentiometer would be the most straightforward in that case, if it would fit...
Guys,
perhaps i am wrong, but i think there is a failure in the BOM.
We need 4x 100 Ohm resistors, not two...
You are right. The qty should be 4.

You could think about using an motorized ALPS poti (RK 27 112MC).
There are also kits available with pcb, IR-remotecontroller.
But if it fits into the new diyAudio case for the B1 NUTUBE ???? 😕
Only some thoughts.

Very beautiful look, nice clean work as usual
Which switch was used for input selection?
