Hi Mr. King, or may I call you Toaster. ;-)

I have a design which calculates out to be able to double
the horizontal frequency +/- 2%, but I haven't found a place
that will sell me the minimal parts needed as yet. I don't
spend a lot of time on this project as I have a few others
which I would like done first, not to mention all the other
things I do. I will probably get back to it once I am finished
building these hard drives for customers. I know it can be done
and I will make it work soon. Give me a little more time.

Thanks,
