Re: Common Crate VC Problem??
I don't know the answer to your problem offhand...  
 
I'd start troubleshooting by pulling the preamp tubes one by one, starting with the ones closest to  
the input and listening for when the static goes  
away.  
 
Once you've isolated it to a particular stage  
probe with your chopstick, measure voltages etc.  
in that particular area. Give the socket for that  
tube a good cleaning with some deoxit.  
 
A likely suspect would be a failing plate resitor.
