New any Geiger Counter/ CDV-700 SPEAK2ME Speaker-LED Driver PCB (Clicker)

Description

.00 shipping to USA (First Class, tracked) for any quantity.
Cloned from the original and rare CDV-705 add-on speaker. Can be used to rebuild/replace CDV-705 electronics.
Add sound to any 3V positive ground Geiger Counter, especially tailored for the ENi CDV-700 6B and the resulting upgraded LENi Geiger counter.
Also can be used as a stand alone by providing power from two AA cells-  add sound to typical bench mounted SCA's, scalers and other pulse instruments that normally don't have speakers, but using their "AMP" jack on the back if so equipped.
Instructions are located here:
Use your own speaker and other parts as needed for your project - the larger the speaker is, the louder it will be.
This is NOT an audio amplifier per se. It is a clone of the CDV-705 which is a monostable multivibrator. It does not allow the HV whine to bleed into the speaker continuously like an ordinary audio amplifier does.
