Post Turntable strobe

Just found a box of these after a mega clearout.
I supplied these to a manufacturer as a kit consisting of:
Assembled PCB
LED (8mm ultrabright red), with bezel
Push switch
The PCB has a 3.2768MHz crystal, a CD4060,a CD4013, and a couple of transistors.
The strobe pulse-width and frequency (100Hz), was optimised for 50Hz turntable strobe illumination.

These make a good turntable strobe, or could be used as the basis of a turrntable PSU. Please though, be aware that it's output is 100Hz, and would need another divider chip (such as the CD4013), for the PSU application.

I will accept 5 to UK or 10Euro to Europe post paid.
BTW This is 1/3 of the eBay price.

Please email me if interested.

Cheers,

Thumbs up Just to make things clear:

This will work with any 50Hz strobe marking.

Can ship to UK / Europe only at this price.

Proceeds will go to diyAudio, less postage costs.

Default Bump

15 to go.
Diagram attached.
All that's needed to complete it is a push-button switch and 9 volt battery.
No schematic is available, but it wouldn't take much to trace it out.
