Crack with speedball specs

[RSMaxwell]

I'm getting lazy in my old age, so I'm just asking rather than texting or doing a in depth search...

What is the Crack's output impedednce/load? (120 Ohm?)
What is the Crack's output amperage?
What is the Crack's output voltage?

What is the Crack's output impedednce/load? (120 Ohm?)

That's about right.  It will depend a little bit on the specific 6080 (or 5998) used for testing.

What is the Crack's output amperage?

+/- 30mA peak to peak.

What is the Crack's output voltage?

This is extremely dependent on the load the Crack sees.  I don't think you'll get much more than 13V RMS out into any load.
