This is one of the most popular projects at Torres Engineering.

Adding a complete tube driven reverb circuit to the Champ amp.  

it is the whole thing, adding two tubes, reverb transformer, jacks, control, 3 spring reverb, circuitry, power supply modification - everything to make a Champ into the sweetest little amp ever.
