De rien mon pôte. My RP was like yours until the C35M chucked off its mortal coil. I've replaced it with a C35A which as you say has the little box on the top. Assuming you're still 6v on three brushes, set max output at no more than 8 amps, and summer at about 1 amp. You might have to fiddle about with the length of the resistor to reach a happy medium.
