Styroflex

These surplus Remix styroflex capacitors are not the extended foil types.

Hi,
what is an extended foil polystyrene?
How do you recognise it?
How bad is a polystyrene that is not extended foil?

I thought aluminium foil and polystyrene insulator were all that was needed for a good audio cap.

Do they make stacked film polystyrene?
All mine are clearly a long continuous coil.

These surplus Remix styroflex capacitors are not the extended foil types.

What is an extended foil?
What tells them apart from a not extended foil?

Rifa say that the leads are soldered to the foil.
Does that mean the foil is lead and not aluminium?

Unlikely to be lead. It is possible to solder to aluminium.

I missed that.
Thanks for pointing me to the answer.
