I am considering using 2 stacked I-Selects for balanced input selection.
My plan:
- Top board for left channel
- Top board power circuit populated (diodes, 7812, etc.)
- Bottom board for right channel
- Top board DC OUT connected to bottom board DC IN
- Connect G,1,2,3,4,5,6 from top board to G,1,2,3,4,5,6 on bottom board
- Connect selector switch to top board
Some inputs will be unbalanced. I plan to jumper IN- to GND on the I-Select boards for the unbalanced inputs.
If I use an arduino rather than a physical switch, I am considering using arduino output connected to 2N5551's to power the relays.
Any comments would be appreciated.

The last GB for the end of the year has started and will close out on 12/9/2018.
If you have signed up on spreadsheet previously, I should have private messaged you by now on next steps.
The Reflektor-D boards will move from matte to standard black.
So, to get in on GB please sign up on spreadsheet and then private message me. Any questions, private message me.

For the on board LED, what is the correct +/- orientation? There is one round via, and one square.

This may help. Check the breakout on the second pic down on right.

Shows flatspot of cathode, or shorter lead.

Thanks for the info. Just to be sure I understand correctly, is the via with the square pad cathode?

Yes.
Long leads to left. short to right.
Hi,
Just a quick question that I have not seen asked. Is there any reason why I could not use the I-Select as an output selector? For example, input a signal on the output side and the use the selector to choose one of several outputs (traditional input side), so I could choose between several amps or preamps. Hope that it is not too dumb a question.
Thanks.

To choose between several preamps from one source yes. Between output of one preamp to several power amps yes, between output of one power amp between several loudspeakers no, because the relays are not rated for switching & passing such high currents (1A switching, 2A carrying max).
Ok, like an idiot I connected 34VAC to the input rather than 17VAC. The LED came on for a short while and then went out before I realised what I'd done. What have I likely trashed, just the 7812?

Did the 7812 get really hot first?
It would have tried to down the voltage. If not left on for more than a minute, I would be surprised if the 7812 itself blew. It will always try to output 12V. Assuming it was left on and overheated, it is a good candidate to replace. Might want to ask Salas about troubleshooting it. I can't seem to find the technical thread for it right now.

Do you still offer the 'kit' as an optional extra? IF so what is the current cost please?
Thanks

Yes, price for 4positions is 36.00. Since no large caps or large heatsinks is needed, should be able to ship as a flat for not too much money for internation buyers.
Good day.
Are the Ebay dact type pots pin compatible with the layout on the PCB....from a schematic point of view....I realise they may not align. I shall figure it out myself somehow I guess but I just thought I'd ask if anyone knows of the top.

You may have to run wires from the boards to the pot. All the cheap DACT type pots I’ve gotten from eBay have had lugs not pins though...
