A Z-50 is 7 uh. This would be suitable for a VHF amplifier, as it would
have a reactance of about 80 ohms at 1.8 MHz. Many amplifiers have
pie-wound 1 or 2 mh chokes in this position; however, since the type of
chokes used are often rated at 300 ma, they would possibly burn out
before blowing a fuse if the blocking capacitor fails.
