In Reply to: RE: Film cap off rectifier posted by dee eye why on September 16, 2014 at 10:43:52
What effect would a smaller cap have in this location?
A smaller C1 will always present less loading to the rectifier - tube or SS.
Also, faster recovery time which translates into a faster sonic signature.
Depending upon other factors, you may or may not hear the difference but the rectifier will notice it.
Cheers,

...but probably by an insignificant amount (for example, 15 µF in place of 20 µF might only reduce the output voltage by a couple of volts.) Also, film caps "punch above their weight" due to the smaller equivalent series resistance, so the final B+ voltage might not change at all
Whether you use a reduced capacitance or not, a film cap will sound faster than an electrolytic (in a good way, that is clearer, not harsher.)
