Re: Help with old marshall head
I don't know about the tremelo, but the other problem sounds like one of several possibilities:  
 
1. Unwanted positive feedback due to lead dress problems,  
 
2. Arcing on the power tube sockets or high-voltage lead arcing to the chassis, or  
 
3. Physical vibration within a tube (preamp or power amp tube).  
 
By the way, I'm assuming you have already replaced the filter capacitors. If not, do so. Angela Instruments, (301) 725-0451, sells exact replacements for $5.50.  
 
Good luck!
