for the first time, after months i got a error message, capacitor reverse voltage ..., witch seems logical, as it's coupled to a active voltage divider, charging from the negative side.
I need a non polarized.
At first i went mouser to check for Wima 10uF, but the thing is 16 mm high and 11 mm width (MKS), it doesn't fit between stacked PCB's, max 10 mm, unless i paste it on the back, looks a bit unfinished.
i turned on the my scope and synthesizer, my VCO is Make Noise STO, i just found out my VCO can output 25.5 kHz.
I did several test, using Wima's: 47nF, 100nF, 330nF, 1uF and 2 electrolytic 4uF and 10uF.
(a 3.5 m socket for the patch cable with wires soldered on the breadboard).
they are all pretty much suitable so far i could see, the vco (Buchla 259 based) in the high end seems to loose a bit of amplitude.
the line audio input module i made (some years ago), i toke from Befaco inamp uses a 56pF, now they use 47nF.
Most of the time, in many schematics they use either electrolytic 10uF or 4uF7.
I think, i will opt for Wima 1uF.
Now i have been buying all these values, 220nF, 470nF, but looks like unnecessary and could settle for just one (1uF).
What's your thoughts?
