Large ferrite U cores

[phi1.62]

Is anyone aware of a store that sells large ferrite U cores for use in the construction of high voltage and high frequency transformers? I remember someone selling them on ebay a few months ago but I missed out on the opportunity to get one. The ones sold on ebay were TDK UU series cores, Model Number PC40 or PE22, size 79 X 129 X 31 mm. The following webpage outlines the construction of such transformers but there doesn't seem to be an email on the website to contact the owner regarding the core he used:

I would appreciate your assistance.
