Thanks Myles!
Here's a bit more...
I think the EL-84's I got from Bob were both at 36 ma... a perfect match, but lower ma than you had mentioned (I think you mentioned 47 ma)... What would be the difference?
I believe the "4 points" I mentioned regarding the 5751 were 4 ma (i.e. both sides were within 4 ma of each other)... so around 2%... That works for the pi/driver slot right?
