So, I gave in and ordered a Radial ProRMP. Immediately, I dissasembled the bastard to see what it was made of. Pretty much exactly the same as the Jensen reamp other than three extra resistors. Wow. Shit cost me $100. I lost my internet connection, so I don't have all my gut shots (the construction is good), but here is a circuit diagram I drew up and an image of the jensen schematic. You can see the similarites.
