Nick, I don't remember what scope you bought, but you'll definitely need two matching 1x-10x probes. I've got a pair of probes similar to these:
http://www.ebay.com/itm/2-of-x1-x10-switchable-100MHZ-Oscilloscope-probes-4-HP-Tektronix-RIGOL-OWON-600V-/150915635553?_trksid=p2141725.m3641.l6368
They are adequate for low-frequency everyday use. You can spend a lot more on probes but these will suffice to get you started.

Most of the time you'll be using the 10x setting on probes/scope channels. 1x is for very very weak signals, and reduces scope bandwidth and also loads the circuit more than the 10x probe setting does. The cliplead thing you've described really shouldn't be used with a scope, it's more for Signal Generator output connections and stuff like that. You can use it with the scope but be very careful, high voltage spikes through this non-attenuated cable can blow out your scope's front end. You can use your 100x probe, but for general purpose use you really do need a pair of matching 10x probes.

As far as running the Mazilli goes, you may not be getting it to start oscillating if you connect it to a power supply and then ramp up the voltage. You should use a switch to turn the Mazilli on "hard" to a power source that is already set at the voltage you want to use. Generally they will start oscillating right away if you do this, whereas the slow ramp-up may cause a non-start, which turns just one mosfet on fully, and it will blow that mosfet quickly. Oddly enough sometimes a Mazilli will oscillate with only one working mosfet, but of course you don't get the proper power output when it does that. The scope will tell you what is going on.... Look at the mosfet Gates wrt ground (Source), or the mosfet Drains wrt ground, or use one channel for Gate and one for Drain on the same mosfet, both referenced to Ground.

  TK: Ok, thanks for the info.
  Here is some pics of my scope. If you click on the pictures you'll see the probes and extras that came with the scope.

  The Mazilli did run on just one of the two fets, and both were getting very hot, which was what surprised me, as the shorted fet was shorted "on", instead of off, like is usual. Anyway, I replaced it, but, the problem is with the PS, as it cuts out when I hard drive the Mazilli. I'll know more about it today or tomorrow.
  I'll get some of the 1x- 10x probes when I can.  I do have access to a signal generator, which came with no probes, so maybe the probes that I have now with just the crock leads will work on that.
  I would really like to be able to replace the Mazilli with a commercial TL494 board. There are some that do have a push-pull topology.  I just don't know enough about it to know which one to chose.

  Maybe something like this:

  Or something like this, if it were available, from Oleg:

has any one used this unit built it and ironed out the bugs in the hard ware ? Also i don't understand why Nick wants to use a pulse width device instead of this fixed resonance capable device, as pulse width is not capable of achieving resonance because it's variable frequency, due to the varying pulse width. The bugs could easily be removed if the circuit is modified correctly.

[TinselKoala]

pulse width is not capable of achieving resonance because it's variable frequency, due to the varying pulse width.

No, that's not quite true. Varying pulse width, as most PWM controllers do, does not necessarily entail varying frequency. Many PWM controllers use a fixed frequency and vary (modulate) the ON duty cycle of the pulse (pulse width) from 0 to 100 percent.  Hence "Pulse Width Modulation".

In fact, I've demonstrated a system using a PLL chip to generate the correct resonant frequency, and lock to it, while using a RC-coupled Schmitt trigger logic gate to control the pulse width to make it very narrow. A similar thing is happening in the bottom left part of the schematic above.

[NickZ]

  Here's the board that does both 0 - 100% duty cycle, which is independent of the frequency, which can also be modulated.

  I just don't know how to tie something like this to the yoke/grenade circuit. 
  The Tl494 board that I previously posted only modulates the frequency, but not the duty cycle.
   
   Anyways, I've been playing around with the scope, but would like to know the way to figure the math on the running frequencies, as there is no read out on this scope.  I've been using the 100x probe for now, to monitor and tune the Kacher by just placing it near by, but that won't tell me at what frequency it's running at, as that will vary with the distance the probe is away from the signal source
