Yup, that's the one. Machine work was very well done, everything lines up, sits level, not a scratch on it when I received it. The source selector has holes for LEDs but I have not seen anyone make this chassis and develop a way to have LEDs light up with your source position - that would be extra cool.


It looks legitimately high-end sitting on the shelf

It's really nice but "I" have to support the store. Diyaudio is my lifeline to learning. Couldn't do it without them.
But, Congratulations your whole build is beautiful.
Regards,
Don

Hello soundwavesteve


just duplicate the line selector, one half selects the input and the other selects V+ for the led you want to turn on.
Something like this:

Ah, simplest solution is best! I don't know if I can do that with Glassware's Select Switch:


Stereo selector switch


If my power supply wasn't in the way I could put the GW switch as second behind another switch that was connected to the leds......

You'd need a different switch, there's a drawing in this .pdf that would help explain. It's pretty easy. https://www.diyaudio.com/forums/atta...i_select-2-pdf

from here - GB For Salas I-Select Mesmerize Type input selector and volume control

Question Stereo Selector Switch

Has anyone tried the Stereo Selector Switch linked in post 1716? The selector switch itself could be a rip-off of the Mesmerize, but I am primarily interested in the relay operated volume control: 128 steps! Besides the selector board board is possibly available through Tea-Bag if I can get in on a GB sometime Two of these goodies could be used to drive a BBA-3giving tracking as accurate as the builder was fastidious, as long as they were kept independent it could also allow for balance adjustment. Hmmmm, I'm interested especially because I have two BA3Gs ( only one of which is yet populated, but that could easily change,,,.

I use the Glassware one from post 1716. Not sure where you are seeing 128 step volume control though.
