Unfortunately due to time commitments, my plans have changed in implementing this well received LDR remote system in my DIY project. You guys have read the reviews, it has won the Absolute Sound 2016 Golden Ear Award:
http://www.tortugaaudio.com/articles/ldr3-v2-2016-editors-choice-award/For sale is an unused and brand new,
(1) IO3 relay board, (1) PS12.5 power supply with dual 12V/800mA outputs including toroidal transformer. I would like $100 shipped in the US + 4.5% if using PayPal. If international, shipping is extra and as quoted by the mail carrier. Everything will be shipped in appropriate antistatic bags so it can arrive without incident.
Pics (only to show what everything looks like, remember you are only getting the above
bolded items for sale):

This is the dual pair of LDR3x.V2 Passive Preamp controller for a fully balanced volume control. The unit is fully upgraded to the most recent firmware by Morten Sissener.

Dual IO3 input boards and it works by relay switching.

Dual DM1, display modules, with a blue color as you see on fully built Tortuga LDR preamps.

Toroidal transformer and PS12.5 power supply with dual 12V/800mA outputs.

Apple remote, infrared receiver and connecting cable - which is sold.

The whole package.

Everything fully packed in antistatic bags to arrive safely.
Thanks for reading. As an aside, I really want to sell everything at once. Essentially if you were to build this as a single ended (unbalanced) volume control, you get an extra volume control for a nice discount that you can use on another project. Best,
Anand.
