I finally got around to building my Electrovibe and it sounds so good. Only issue I'm having is when I increase the speed knosb (happens on both knobs), the bulb will pulse faster then once maxed, the bulb will remain always on. I have tweaked both trim pots across the full range to see if that was affecting it, but no avail.
Below are some photos and a link to a video. Let me know if more photos or details or needed.
A few things to note - I socketed a few resistors (R4, R12, R14, R15, to experiment with Big Monk's modifications (https://forum.pedalpcb.com/threads/electrovibe-modifications-thread.8703/). At the moment the only resistor that isn't per specs/manual is R12 for the Extended Range at Slow Speeds mod (manual calls for 2.2 M Ohm; I have a 10M Ohm resistor in it). The other 3 socketed resistors are as per specs.
Bulb is VCC 7371 (https://www.mouser.com/ProductDetail/VCC/7371?qs=N8%2Bk0S5zvCYBBpiHgR%2B78A==)
Photocells are NSL-7532 (https://smallbear-electronics.mybigcommerce.com/photocell-silonex-advanced-photonix-nsl-7532/)
Thanks!
