Why are 813 tubes considered 'dirty'? I have an old amp in the attic I haven't used for a long time that has a pair of 813's in it I have read somewhere that they are a very 'dirty' tube. I'd assume that means lots of spurs or something. Just wonder why that would be. 73 Tom W7WHY _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
