[AMPS] 572-B Input impedance??

[Phil Levin]

I need the approximate input impedance for a pair of 572-B's??  I am
working on the input matching on an SB-200 to six meters.  Abt 60ohms??

Still have parasitc oscillation problem and am suspicious abt the plate
RF choke,  dipmeter shows resonance at 52 ohms???  Any ideas??  I may
try to wind a new choke.

TU, Phil W2GE
