Hello Lee (if I may be so bold as to call you that :-)
I have a question.  I have a Randall Pro-Tube 1000  head (55 watts, 5 12 
ax-7's and 2 6Ll6's) with a slight problem.  After it heats up, it cuts out, 
ie there is no sound at all unless I flip it into standby and then back up to 
full on.  I am inclined to think that it is a capacitor that has dried up, 
but I am not sure.  It has only started doing this after I replaced the 
6L6's.  I replaced them with some Groove tubes from woodwind/brasswind, and 
they seem to be working fine.  The only reason that I mention this is because 
there is no Bias adjust screw on the Randall (maybe they took a Mesa-Boogie 
approach to amp building), so I am not sure how correctly they are biased.  
They don't seem to run too hot or too cool, but I wasn't sure if this would 
have anything to do with the problem I am having now.
Also, is there some way to adjust the bias on Randall amps that I just don't 
know about?  If not, where can I get Randall tubes?
Thanks for your time :-)
