This auction is for two items, a Parma 45 Ohm Pro Turbo slot car controller  and a Coast Computer Design Powerhhouse controller upgrade module. They work well and are in good condition. It basically turns a regular resister controller into an electronic fully adjustable controller. There are 3 areas that are adjustable, the brakes, whether you want the controller to response to be linear or exponential, and the start speed. In order for this to work, your Parma controller must have a 45 Ohm resister. You hook the controller to the "module" and then hook the module up to the track. It works. Here's what the manufacturer Coast Computer Design says about it: Their website is at . PowerHouse Slot Car Controller The "black box" that turns a simple resistor controller into a fully electronic controller, setting a new standard for features, reliability, performance, and price. Just plug a resistor controller onto the box, plug the box onto the track, and you get massive power handling plus a full set of electronic controls. Great for all classes of slot car, from 1/24 scale open down to H.O. Wide range controls allow optimum settings for each type of racing, including wing cars and drag racing. "Handset" can be any 45 Ohm controller (any value between about 35 Ohms and 100 Ohms will work).  This is the perfect upgrade to a "starter" kit. 40 "Bands" (using a Parma 45 Ohm resistor) allow fine speed steps not available on 8-band controllers. Or use an 8-band handset to get that solid "hanging resistor controller" feel but with the flexibility of a fully electronic controller (just replace the huge hanging resistor with eight tiny "6.8 Ohm 1/8Watt" resistors from Radio Shack). "Start Speed" knob sets speed of car at first band. "Response" knob allows you to easily customize the "feel" for your driving style, car, and track, or to match the feel of any other popular controller. In full "linear" position it feels like a resistor controller. Back it off toward the "exponential" setting to stretch the slower speeds out over more of the trigger range, as sometimes needed for road courses or specific motors or cars. "End Brake" knob is fully variable (0% to 100%) "Active Brake" switch allows forced deceleration throughout trigger range (more like a transistor or diode controller) or turn it off to get the feel of a resistor controller. This can tighten up the feel of a car with poor motor braking, or loosen up a car that has a lot of motor/gear braking. Fully protected against every possible alligator clip mis-connection, and against short circuits on the track. Switchable polarity for "reverse wired" tracks, allowing use worldwide. Scale Racing Features Separate Start Speed and Response knobs allow all of the settings of a single "sensitivity" knob, plus a lot of "in between" settings that are not available with "single knob" controllers, allowing you to fine tune for each car/motor and track. Drag Racing Features Start Speed knob allows super slow speeds for perfect control over rollout, and super high speeds for fastest trigger response when racing. Note: PowerHouse requires that its "Red" track wire be connected to the track, which most drag strip owners now allow. Wing Car Racing Features Runs cool and reliable even when powering the hottest motors on the stickiest tracks. 40-band trigger allows both slow start-up speeds and fast near-full speeds. 

I will combine items to save you $ and me time on shipping, however...here's what YOU must do in order for that to happen:  Put the items wanted into your "Cart" (DO NOT PAY YET!).  Then request a combined total.  I'll send you an invoice to pay.
