Good to hear. I have a pretty competitive FAN / discount plan, so it would be possible mine would go up in cost. Can you get SIM cards for other devices to share data? I should probably RTFM.
Maybe they sell a cigar fridge that you can put wine in? Those are New-Air. They are quiet and very cheap to run. I plan on expanding with more... maybe even some with wine in them.
Right - so I am proposing to replace the two diamond buffers with a single SIP-8 pinout with external resistors that can be shorted to run the discrete opamps as buffers. Then the existing buffer boards could be made double sided (stereo) if desired.
