MB Mark IV Power Tubes

MB Mark IV Power Tubes
Currently have a Mark IV combo, running it in the  
duel 'EL34', duel '6L6' configuration.  
Purchased this set of tubes from MB. Sales person  
said that whether you run this amp with this or the  
4 '6L6' setup, the 2 outer tubes must be a matched  
set and the 2 inner tubes must be a matched set.  
Ok understood.....  
Can I buy other tubes, JJ or NOS in matched sets  
and use them in this amp with good results?  
Mesa probably buys tons of tubes, tests them and  
pairs them up within a certain range.  
Any info on this subject would be appreciated.  

John Stokes You certainly can buy matched pairs... -- 9/16/1999 8:24 PM
