If you're interested in stuff like ACTS then you shouldn't be afraid of a discriminator tap, it's easy. Look up your discriminator output pin and then solder one leg of a resistor to it, I tend to go with one a bit lower than 10 kOhm like 5.6k. Drill a 3/8 inch hole in the back of the case (taking care that your drill doesn't slip and drill something on the circuit board once it goes through) and screw an RCA jack in there. Connect the other end of the resistor to that or extend it with a resistor leg or what have you. That's basically what I do, YMMV. Ask someone more experienced to help you if you're worried.
