Re: less bass mod...
Hi Nathan  
 
The most common "defart" mod :  
- change all 0.1 coupling-caps to 0.047s  
- change the cathodebypass-caps on V1 and V2 from 22u to 4u7  
 
Another "trick" is to use a 5V4 rectifier ( or 5V4-style Weber coppercap ) for a bit more tightness at higher volumes , you gotto check the biasing 'cause the plate-voltages do slightly raise .  
 
Hope this helps , keep on rockin' !  
 
Chris
