Re: Cathode Bias / Fixed Bias Switch
I have.  
IMHO, in this 5E3 circuit, I think the cathode bias sounds the best... plus the B+ voltage rises about 20vdc when you switch to fixed bias.  
 
The brownface Princeton has:  
1.) fixed bias...  
2.) a totally different volume control  
3.) a single channel (no interactive volume pots)  
4.) vibrato/trem  
all four of which completely changes the way the amp sounds and feels when being played!  
It's a great sound, as is the brownface Deluxe, but they are different amps.
