Plate current range for 6L6 and EL34 tubes in Mark V

[kreatorkills]

Can someone please tell me the proper plate current range for 6L6 and EL34 tubes to be used in a Mark V. The highest and lowest on each that would be safe. Thanks.

Iv'e got some 6l6's that have a natural current draw of approximately 25ma on my Maximatcher. And in the inner tube slots of my Mark V they get the bias up around 41ma with a plate voltage around 480. The outside pair are biased a little cooler in the Mark V. So when I buy tubes from The Tube Store, The Tube Depot, or whatever reputable dealer,,I always state that I need a quad that have a natural current draw of 25ma for 6L6GC's.
