marshall valvestate 8240
Hi,  
 
I have an aging (series I) marshall valvestate 8240 that is starting to hum fairly badly. Does anyone have a schematic they can send me for the power amp section? Also, if anyone has any experience solving hum problems in these amps I would greatly appreciate some advice.  
 
Regards,  
 
Craig
