Jason,
You can connect directly to the deflection plates for the audio as you describe. Most modern (1970's and later Tektronix and others) analog scopes have a setting called X:Y when the horizontal sweep knob is at max CCW. In this case Channel A is for the X axis and Channel B is for the Y axis. With a scope like this you can scale the audio and RF for any convenient level within the voltage range of the scope inputs.

So all thats really required from a junker scope is a power supply, a functioning filament, and some viable phosphor left on the screen, right?
