Title: RobRob Blackvibe 6v6 build - coupling cap polarity?
Post by: gradyclouse on October 29, 2023, 03:50:27 pm

I am building this: https://robrobinette.com/RR763_BLACKVIBE.htm

The coupling caps (pictured below in schematic, DIYLC layout and photo image) do not appear to be polarized, but the DIYLC does seem to show an "o" at one end of each cap. Are these caps polarized?

Thanks!

If I remember correctly, the little"o" in his drawings indicates the outer foil-wrap end of the capacitor, if you are so inclined.
