testing the Cool Bit OSC-s for seeming L.e.d.spk. measurement

actually for OSC frequency measurement ... anyway

made a real test with hybrid vid.amp ~ dif.amp circuit but it didn't work reliably enough to be sure of the frequency (so i hope one of the next actually'll 2 the 3-ck before i need to set up some opampsh¡t)

1-st Std. (modified)

2-nd -- an emulated tunnel diode (modified)

update 2017.04.25 :: some opampsh¡t
