In lieu of a Hammond Series 193 choke . . . how to test this safely?

Tweakers' Asylum

Tweaks for systems, rooms and Do It Yourself (DIY) help. FAQ.

Here in Tokyo I don't have a ready source of Hammond Series 193 chokes (that I know of). There are a few inexpensive candidate chokes being sold on a local internet auction site that Iâ€™d like to ask about. First, the one shown below weighs 7kg (15 lbs+), and the only information I have about it is what is visible in the photo. My primary concern is that I have no idea what the maximum operating voltage is. Obviously, one way to find out if it works is to plug it in and see whether it results in a fire. However, it occurs to me that perhaps there might be a more intelligent approach to take before I go stuffing "mystery meat" into my AC line's digestive tract.
ANY ADVICE WOULD BE GREATLY APPRECIATED. If Iâ€™m just asking for trouble by messing with this, Iâ€™ll pass. The price is about US$15.
Another item (http://img292.imageshack.us/img292/7361/kamasho01img600x4501173zy5.jpg) is a 9kg (20 lb) "AC Reactor" that was made in 2002 and has never been used. This is a three-phase device built around a nice laminated steel core. (I'm assuming that there are ways of using three-phase devices on single-phase lines.) This is marked as follows --
Insulation: B
Hz: 50/60
Line: 400/440V, 200/220V
A: 140
mH: 0.049
The price is about US$26
If either of these devices might be worth messing with for AC power line conditioning and/or noise filtering, I would greatly appreciate some advice on how to approach.
Thanks!
