The duelunds are 300uf - probably the biggest they make. Custom order I'm sure!

The ESAs have mellowed out nicely.. perhaps something else in the chain was exacerbating the problem.  I have been tempted to grab some mundorf SIOs for it but havent managed to pull the trigger.

I am also interested in trying these.

I have not heard of those... Kind of pricey for a no name! I would steer clear....

I still like the Duelund - not to give you guys a complex or anything!
I need to hang a pair of those under my truck's back bumper. Don't MESS with me!

Adam,

The two largest caps were in a 230V Variable Speed AC GE Drive that was retired.  I don't remember why there are two values and voltage ratings.  What it does is take AC convert it to DC then pulse width modulate the positive and negative DC buses to form variable frequency AC that drive AC motors.  These are early and unsophisticated drives using SCRs.  Not like today's drives that use IGBTs.

 Wolfy, I'm thinking that you wouldn't get far in an airport with those cans! They stopped me once for having an SPL meter.

I missed a flight home from Albuquerque due to TSA freaking out over 807 tubes and a potted PT.  Used to get good surplus buys there, but long since dried up.

Cheers,

Count me among Capacitor-addicted...
Here is my B1 Buffer, with 10uF 400v PIO coupling caps...
They are NOS National Capacitor...I have also their 37uF big brother...they're almost the size of a brick!
