Re: Anyone Got Crate Schematics?
Hello all!  
 
I think that i have found my problem... The tubes appear to be biased a little too hot... At idle for the quad the tubes are drawing 135mA across the output tranny fuse...  
 
It appears to be a fixed bias design, but trying to reverse engineer a circutboard to find the correct resistor is giving me a major headache... ;-)  
 
It is a Crate Vintage Club 50... 4xEL84, 4x12AX7.. Fixed bias design...  
 
Thanks in advance!!!!!!  
Rob W.
