Allan: If you're interested in a simple 2 xstr, sine phase shift oscillator ckt.Check out: WWW.alphalink.com.au/~parkerp/twotone.gif If you need a little different frequency,you can simultaneously vary the 2.2k values or the 10 nf values on the right circuit,upping the 2.2k sets to higher resistance...

Joseph:
I tend to agree with Chris' repair idea # 1.
Liquid Steels porosity in the epoxy binder might be less than ideal and absorb RF. Why don't you
evaluate by mixing a sample on a Pyrex plate and
see if it gets warm.

TNT:<p>Clarification please. I'm seeing a circuit that would deliver a shock to some one/or/thing, but of what duration after it starts operating ? The real killer is the delay time(s) after initialization....1/10th sec is fast ..... but 1/100th sec and 1/000th sec after push button activation? Coul...

Bob: Seems like it was 30 yrs ago that I breadboarded up an " octopus " to evaluate the ckt.Later when I was with NASA I came upon the good fortune to get a Huntoon Tracker for a paltry $ 25 from the surplus property department.....so I repaired same and have been using it since. It makes ...
