Mod Trans for a 813 pair

[w9jsw]

Looking for a mod trans from a Wilcox 99. This is the one that used 2 813s and a 250th for RF. Or any other option for a mod trans for a pair of 813s modded by a pair. I am moving the Gates broadcast iron for my 813 rig to a 4-400 modded by 3-500s. I want to take the RF deck from the 813 rig and shoehorn in a modulator all on the same chassis. The space is there if I can find a reasonably compact mod trans. I run the rig at 2000V at 375ma now but can reduce the power to match the right size mod trans.
