I think I should add more information on what am I doing. I purchased a pair of EXO-050 M4 with FS-030 windings, and I have no idea what to do with them.
Mike, I know that your specs are listed for 20hz - 20K hz. What if anything that I should be aware of if I am using them for a more limited range?

My current thinking is that each output transformer will be used to power either one or two upper bass/lower mid woofers, from around 80hz/150hz to 800hz/1200hz, in an active setup. I am not sure what are the crossover points yet.
I have some 813 tubes and am considering building John's 813 transconductance amp. John is using 120ma plate chokes, and that is why I ask for availability of such plate chokes.
I also have JJ300B tubes, and I can order alternatives. I am open to other suggestions, regarding operating points, tube selection, and everything else.
