Not affiliated except I couldn't resist and bought a set. These things retail for what, $100+ each!? Figured you all would be interested.

Wow, those would be the Family Joules! I did need the 600v rating though.

what could one do with those things...? audio wise, that is

[tomlang]

Filter caps, reallllyyyyy low esr and last a long time, no electrolyte.

[nyazzip]

so you're saying you could use just one of these 200uF caps in place of the traditional capacitor "bank" in say, a power amp? forgive my ignorance.

[tomlang]

In a given power supply, you will have several "stages" such as a CLC (Cap, Choke, Cap) filter then a resistor and another cap for the Phase Inverter tube supply, then yet another resistor (and cap) for the "preamp" tube supply.

Two could take the place of the two C's in a solid state rectified CLC filter (won't reduce the parts count any). For the other two stages you may get away with lower voltage rated caps. In my case, I have a potential (pun intended) project that will have 540 VDC going to the output tubes so I need the 600 vdc rating.

A big problem is these are so big!

Do you know if these are Mylar or Prolypropyplene. Thanks
