PVI: The frontend uses a photovoltaic power supply to eliminate the influence of power fluctuations on the signal path. It uses a G4 LED bulb with a current source to disable the onboard driver of the G4.
Wait, I am looking for a hole to get into

Thank you.

Well I guess we're going to have to go with printing some fewer PCB's and just call it good. Once people's thoughts on the amp start rolling in, then another GB may have to take place.

Jeremy,

In your first post, I find it interesting how you illuminate your work.
From what I can tell it looks like your using a small LED lamp above the pcb, plus some sort of led/lamp shining up from underneath the pcb.

My older eyes could sure use some info on how you illuminate your work.

I think those are the LEDs for the solar cells to power the error correction part of the amp.
