SIL,
Thank you for revelations which I am looking in to deeply.

Can you tell me why you selected that ferrite? The choice of ferrite can have a significant effect on the result.I mean the BH curve.

I wouldn't bank on it. So regarding the Ferrox what did you use for that especially the
3 blanking plates he glues on the top of the two E Cores ?

Is this what you're after?

Well if  i use am radio slab ferrite bar it will be different quality to the E section
I can buy the other half of the other E so i might as well use them as it will be fare easyer
to cut or grind as aerial ferrox is real hard to cut from that period in time besides the amount of
power I use is quite low and I have 4 powere solar cells to hand.

Thanks for the info any way

I don't want to pretend that I know it all but this part of the design seems to be a voltage-fed Royer oscillator.
The first part  (E13003s) is a high frequency astable , modulated by this part.
If you have a high resolution copy of the schematic please send it as I can't read the number of the turns.

Do you have MS Paint it helps
