Silly question (probably) but are caps directional? I would imagine only if they have polarity stipulated?
Logic would dictate not really, but once used in a certain direction for a time, best not to reverse it?

Film caps are reversible.
Some film caps have the outer foil lead marked, so that you connect the outer foil end to the lowest impedance to give a degree of shielding to the cap.
Every day is a skool day.
Indeed sir.Quote:

So, after realising my previously desired caps simply would not fit in my preamp I've decided to go with some Mundorf Supreme Silver/Gold/Oil cap for the higher power (4.3uF) duties. Along with an Audyn True Copper Max cap for the lower (0.33uF) duties. I'm hoping their virtues will complement each other having not really delved into the world of caps much before.

Can't go wrong with the Mundorfs I don't think. Haven't tried the Audyns.
I'm hoping so Ali, also anything Mr Firebottle recommends can't be all bad . . . .Quote:

Did you try the Audyn true copper max? Only asking because I have some 0.33uf for sale.
Tried them, love them. They certainly add something to my pre-amp (which has other issues unfortunately). When it was working it sounded excellent. I'm actually just looking in my other pre-amp to check the value of the caps as I'd be looking to put them in there too.Quote:

Very natural sounding with no glare I thought. But not dull either.Quote:

In the end I replaced them with some much smaller Mundorf Mcap evo oil and now there is silence. If I could put them back in without the hum I would :(
I wonder if it's the 5" long wires I have to use to attach them to the circuit board? Tempted to try something like screened cable before selling...
Could try (gently) heat-shrinking them up to where they meet the board/cap. Might help if the hum is related to electrical noise. They are large, I was using them in conjunction with Mundorf Supreme Silver/Gold/Oil and the combination is something I won't forget in a hurry. Unfortunately the memory is all I have at the moment as like I say my pre-amp is playing up.Quote:
