Ero KT1800 capacitor

[stenak]

I have some Ero MKT 1800 capacitors, 0,1uF, that I want to use in my DIY 6v6 pp amp. There are a black"ring" on one side of the capacitor. How to connect the capacitors in the curcuit, between the stages? The black ring to the input or output stage? The black ring against the 100k resistance or against the 270k resistance?

Black ring indicates the end connected to the outermost wrap of the foil or electrode. Usually you want this end connected to the lower impedance side of the circuit to help with possible noise pickup. That generally means the plate of the driving side rather than the grid of the next stage.

Agree.
