Hello

My name is Joseph from Melbourne Australia.

I have a question about power supplies.

I have a 55 metre scalextric sport track which has booster cables soldered on spread evenly and had no issues running the standard c8217 scalextric sport power base with the 2 x c993 standard transformers that you get in the sets...however instead of using the standard scalextric 60 ohm controllers i used the Parma Economy 25 ohm controllers so all was ok....

This is the question?

I have now purchased the c7042 scalextric advanced 6 car power base. I am using the scalextric digital controllers with 2 of their c 7024 15v 4 amp power supplies.....i am still running it in analogue mode with 2 analogue cars only and im finding i dont have the same amount of power as i did before.........i dont understand this as i thought i would have much more power!!

Scalextric in the UK sent me an email saying the following and i quote, "I have spoken with my colleague who explained that standard analogue transformers were not regulated so could give an output of up to 20 volts even though there are only 12 volt transformers. The new 15v transformers are regulated so will not go above 15 volts and therefore will not be as fast."

If this is true and the 2 x c7024 transformers were designed to handle 6 digital cars in digital mode how come i have less power running 2 non digital cars in analogue mode???

Any ways i think i should buy myself a variable dc power supply so i am able to adjust the power to my liking but i would be really appreciate if you can show me or forward me some material, links or any how to you tube links on how to wire it up to my 6 car power base.....i have already purchased 2 x 3.1MM x 6.5MM DC Power connectors.

Looking forward to hearing from you with your wealth of knowledge and experience 

Ooh ooh! I think I know this one..

PWM!

The biggest difference between original analog and analog through the digital base is that the digital base is sending PWM (pulse wave modulated) DC. I think a dirty track will have more impact on a PWM signal from the digital base.

Oh, and get some INOX MX3 on those rails.

The variable PSU should be fine.

With the rails properly treated with INOX MX3, I think you'll find the performance of the cars much more comparable.
Sean (hankscorpio) made a great point about the controller, though. Before splashing out on six TruSpeed controllers, give the OEM controllers a tune up. A softer spring (Parma economy/standard) and a good clean will work wonders. After that, you can tweak settings in the base for different cars.

Follow the links in my sig for helpful info on applying the INOX or setting up the base's options.
