What do Oil Caps do and how do they effect sound?


Being new to tubes I would like to know what Oil Caps do and how it changes the quality of sound. How does it work?

Also, on the amplifcation side of things why does Solid State have higher wattage than tubes?

Brooks1,

The sound was exemplary, if I may say so!
The sound was very transparent, plenty of high freq. & low freq extension & since I was listening to single-driver speakers (Cain & Cain Single BEN & Carolina Audio JTM) the sound was so very coherent i.e. music had very good timing! With the ASL SETs, the midrange was additionally magical.

If you have the inclination, I did write a lengthy report on my ASL/single-driver experience. It's long, so have been warned! :-)

They smooth out the sound (more refined sound). Given more details and seperation, music notes have more decay and body.
