Thanks to all for the information. The Humble Homemade Hi-Fi Capacitor Comparison was exhaustive and informative. He has a better memory and ability to compare than I do. Or maybe he has a better setup for comparing capacitors than I do. But it was a great read.
The birthday caps (Mundorf Silver/Oil) came with the Teflon tube sockets for my Paramours. I just wish I could get a pair of sockets for the 76 drivers. The ceramic socket is unreliable, needing re-tensioning periodically.
Again, thanks to everyone who posted.
