[Boatanchors] HV Rectifier Filament Trans-Problem Solved

Thanks to all who replied.
 
I found what I need.  
 
I've decided on a different approach to my problem:  a 2000 vdc power supply that uses a filament tranny with 2000V secondary insulation (a bit too close for me).
 
I'm going to use solid state rectifier blocks (K2AW or similar).   They will be mounted on an aluminum plate directly above the rectifier sockets using spacers and the existing mounting holes for the sockets.  The sockets and filament tranny will be left in place with no modification (except to move the filter connection from the center tap to the rectifier blocks).  I've used these blocks for a few years with my Gates BC-1G and have experienced no problems 
 
Thanks again,

I need to replace the filament transformer in an existing 2000V power supply.
 
I'm using 3B28s, so the required voltage/current is 2.5 VCT @ 10 amps or 5 VCT @ 5 amps.  I'm looking for 5000 V insulation or better.
 
If you have something, please tell me the dimensions and style (method of mounting).  I've got to make it fit!   The existing transformer has a "U Frame" mounting and is located under a 4-inch chassis.
