    Excellent video. Your “walk through” of the schematic was very helpful, don’t worry about the length of your videos, your explanation of how that meter works is better than 98% of the other electronic videos out there…

    Thank you for sharing. There is a red wire routed between two e-caps, in the middle of the board. The builder used the caps to turn the wire from vertical to horizontal. I would think that the extremely close proximity to the caps might lead to the introduction of noise. You might want to move it. I also think this routing indicates that the unit was kit built. Multiturn calibration pots might be a nice upgrade.
