[quote][i]Originally posted by iti20090[/i] Hi Folks I used a simple Tip36c transistor set up, bolted to the frame of the Parma Economy controller, for Scalex and S16D for a friend's commercial raceway operating on a "dry" wood surface. This was ok but the 6 x 18 ohm (total 108 ohm) wiper board chain was hopelessly too mushy with S16D on the sticky traction surface at our club track. I switched to the new AB 6 x 5 ohm (30 ohm total) chain, which was far better but the two AB style 10ohm pots are difficult to come by and expensive in SA. Willem's original set up with the 50 and 250 ohm pots seems a more attractive option, cost wise, but I wondered if I would be back to the same "mushy" problem again - maybe it is more problem of the Tip36c transistor than PNP transistors? All advice would be most appreciated.
