Carl,

Would you mind sharing that design with us? My experience of 572B's is
that they are something akin to swine to sort out the parasitics on. The
KW1000  (a UK made linear in the same size box as a 30L1) used a pair
with about 3 turns 3/4 inch diameter and 3 off 33ohm 2 watt carbon
resistors in parallel, but I always felt it was a bit dodgy.
