I managed to find only specs for TDK ferrite core PC40 series but nothing on the older PC30.

Is there any source available for datasheets of cores made in the 80's and 90's?

I found a datasheet for PC30.  I'll try to get it uploaded.

what are you working on with such old material?

PC30 material datasheet:
http://www.filedropper.com/pc30

a lot of this stuff is hard to find since it was only originally published in databooks which very few people have.  Ferrites were a pretty specialty item in the 80s

I found an interesting project of current fed Tesla resonator at http://www.sentex.ca/~mec1995/circ/hv/ss-tesla/ss-tesla2.html and I was looking to compare the original core to the ones I have available on my shelf (ETD59/3C90, ETD59/N97). I built a few very large spark gap based Tesla and Oudin coil but this concept is quite new to me so I would like to play a bit with it.

So far, judging by the original datasheet PC40 seems like a more or less improved PC30 ferrite and the core size in the original project is quite close to ETD54 so ETD59/3C90 that I have available should be able to perform OK. I plan to make complete new electronics since I would like to add overcurrent protection and also it has to work on 230V AC.

It shouldn't be much of a problem for electronics to handle larger cores and higher power at the 110 kHz but very little data is available on this type of current fed resonators so I can just guess how much power can the resonator coil handle in its original form which I plan to use initially.

i found a link for page that wants to sell, i know you already have some, but there are some specs on their webpage, they may help..
http://www.alibaba.com/product-gs/1552046515/PQ2625_pc40_tdk_ferrite_core_for.html..
edit this may help :
i uploaded file as it's freely available and small in size, so don't shout at me i'm still hungover..

This last table is quite useful for quick comparison of ferrites.  Smiley
