Sowter (England) offers inductors specifically intended for choke I/P service.
The Hammond 193Q is a (sic) 21 lb. behemoth, which is rated for 500 mA. Even with a 50% derate, it should easily do the job.
Viscoelastic mounting is probably a good idea, regardless of the make of choke you use. The 1st inductor in a choke I/P filter works HARD.

hey-Hey!!!,
The UTC CG-103 is a 250 mA swinger. 5-25 Hy between 250 and 25 mA. There are Triad endbell versions in 200 and 300 mA and these will do a significant fraction of that in DC output. I used a Triad C-19, a 10 Hy/300 mA choke with 400-0-400 into it, and it delivered 220 mA comfortably.
cheers,
Douglas
consider also the Chicago 8200, an 8Hy/200 mA device, by the indictance curve I saw, it will tolerate input duty w/o complaint at the level you propose.

How about the Triad unit from allied electronics?
16.00 US.
Triad 200ma
I just bought a couple of these for replacements in Fender guitar amps.
Triad Magnetics
Inductor; 6H; Smoothing Filter Choke; 150Ohms; 200mADC; 2-19/32In.H; 4In.W; 2-1/4In.D
They stock others that may be useful also.
