Need A 1200V 5HY Choke

Brutus Need A 1200V 5HY Choke
I need a 1200 volt choke at 5HY for a 211 project I'm working on. Hammond chokes max out at a 1000 volt limit. I searched google and couldn't find any vendors for this item other than those that do custom design work. I want something off the shelf.  
Anybody know a source for HV PS chokes good for greater than 1000 volts service?

What current?  
What freq range? (<1kHz?)

200ma will do fine.  
Not sure about frequency. I'm using it as part of a pi filter in the HV PS. Thought that's 120 cycles. Is there another frequency rating I need to be aware of?

the hammond will probably be fine.  
they're very underrated in terms of specs.

Why not discuss this with Hammond Tech Support.  
They're nice folks.

The standard Ham Radio trick is to put the choke in the ground leg of the B+ assuming you're using a full Pi or choke input filter.

Hey try this (  
Theres some nice links on that site that might find you one if they don't have it. Of course forget custom as it would cost you an arm and a leg.,
