A question was rasied as to the orientation of Sozo caps.
Aiken Said:
In order to take advantage of the shielding properties of the outside foil, the capacitor must be connected in the circuit in a particular orientation.
The proper way to connect the outside foil is to the low impedance side of the circuit
In the case of coupling caps, this will normally be the plate of the previous stage.
If it is a bypass cap to ground, connect the outside foil to the grounded side.
If it is a bypass cap from a signal to B+, connect the outside foil to B+.
The outside foil will act as a shield against electric field coupling into the capacitor, so you want it to have the lowest impedance return path to ground.
http://www.aikenamps.com/OutsideFoil.htmI asked John at
Sozo the following question:
"Some of the Sozo caps I use have a band at one end. Is there any benefit of orienting that in any particular direction such as towards the lower impedance or ground side of the circuit? What would the advantages be?"
and this was his reply:
"Exactly, it
can help with the noise floor somewhat. That's why I provided the line for discriminating users. However [the noise from] the damn heaters seem to make it almost useless! (
) "
So, it sounds like there may, possibly be a noise advantage. No harm in aligning them according to these rules.
