Hi,
I had bought a Harbinger pcb quite awhile ago and still haven't built it yet but I am getting the parts together now and can't source the CdS cells wonder if anyone has a source and part number to help a brother out?
Thanks
Smallbear usually carries the NSL-7530/7532, but they're out of stock right now. They do have the 9203 in stock which also works. Both of these are listed in Bean's build doc. https://smallbear-electronics.mybigcommerce.com/photocells-cds-5mm-diameter/
The 9203 @ smallbear are pretty good.

Not quite the 50M off resistance of the specially tuned photocells they used to have, but those have not been available for a while. I've used them in a couple Univibe builds with success.
