RE: Amp Rectifiers

["adams, john" <adams_john@xxxxxxx>]

A rectifier turns the AC voltage coming in from the wall to DC voltage.  It
does this by taking both sides of the waveform and putting them on the same
side.  Filters then take the peaks off and makes it a steady voltage.  The
transformer makes the voltage higher.

A solid state rectifier usually makes the voltage higher, which may be a
good or bad thing.  I found a couple of web sites mentioning this subject.
I just googled tube vs. solid state rectifier

Subject: Amp Rectifiers



Can anyone tell me what a Rectifier does?  Does it matter 
whether an amp has a tube rectifier or a solid-state rectifier?  
Does a tube rectifier give an amp a different sound than a 
solid-state rectifier?  How important is it to the sound to 
have a tube rectifier?  My Fender "Champ 12" has tube preamp 
and power stages, but a solid-state rectifier.  Would it be 
possible or worthwhile having it modified to tube rectifier?
