Re: Bass pot causes major prob - no More!
original filter cap was fine- i installed an additional  
 
22/450 cap hanging off the rail feeding the 2 100K  
 
plate resistors on the vib. ch. preamp tube. I dunno  
 
about why I needed a 'extra' cap. I have a couple of  
 
Kevin O'Cconner books and he recommends and design with a 22/450 de-coupling cap on EVERY single plate. I do not  
 
really understand this whole power supply business with  
 
respect to caps. Like some Fender Tweeds used 8 uf caps,  
 
then onto 16's, BF mostly 20uf et all. I have a Mesa  
 
SOB and it uses 2 200uf and 2 300uf ..... is there any  
 
good reading on this with a focus on guitar amps?
