Two capacitors in series "add" using the rule
effective capacitance = [C1 * C2] / [C1 + C2]
i.e. two 1uF in series = 500nF.
Is that what you mean by super E?

No, Andrew.

BG's "Super E" configuration is as follows:
* take 2 'N' or 'NP' caps
* connect them in parallel
* when doing this with polar caps, you would make damn sure you had both '+' legs joined together and both '-' legs joined together.
* for the "Super E" configuration, with non-polar caps, each pair of legs consists of a '+' leg connected to a '-' leg.

If you did this with 2 x 1uF NPs in parallel, you would end up with 2uF.
If you did it with 4 x 1uF NPs in parallel, you would end up with 4uF.


Regards,

Andy

Hey guys,

Will you please discuss this to a dull roar?

The GK2 is NOT designed for a SS section cut off, and is not a part of the product. The rules combining capacitors are well known and should not be expounded here.

Cheers,

Hugh
