Sirfixalot, hang on to it for now,  the PURPLE People Eater has not replied as yet.

YesItsPurple:
Well thanks Uncle Doug.
Will look into it this week.
Thanks

Vettech:
been looking for an internals pic.

see attached pic. looks like one 14dip chip - possibly a 555. or a driver with "AND" Gates as inputs.
the ony cap looks like a polyester, thats good, bunch of resisters , diode or two, easy peasy..

Archaic design, notice the "U" shaped metal piece, this is bi-metalic strip achored at one end, then coil of wire heats it up, bends, looses contact, cools, returns to normal, makes contact, heats up and so on...

Any onee with an actual cct diagramm for this device - it would be appreciated... Sorry I cant get the pic on as its too big.
