    Wrightway or Koford Power Supply?

    Hi, new here. Curious if anyone could share their preferences on Power Supplies.

    I am considering the Koford M325J (~$325) and the Wrightway Mini Pro 8 Amp ($300)

    Do these two power supplies basically perform the same?

    What about reliability/serviceability/warranty?

    I am looking to test, break in, and take to the track a unit for everything from 16D's to G7's. I have a couple HO's as well.

    Thanks in advance for your time/comments.

    I use the Koford and I have never had a problem with it, but I am sure that there are not any problems with the Wrightway either.

    The only advice I can give you is look at size and pick which one you like the best.

    Thanks for the reply Glueside. Both brands seem to be well liked by most.

    I am curious if the Korford, going upto 16amps is a better choice only because the Wrightway only goes to 8amps. What would the benefit of having high amps in the slot car world? Would the higher amps really be needed?

    Thanks again for your reply!

    The great advantage to that is to start a motor from a dead stop and see what type of amps it can draw, and the Koford gives you more of a range before shutting off. I have heard of some people starting it from a dead stop to see amp draw and then choosing what motor they will run off of that. I believe they are looking for torque this way, but I could be wrong. I have never worried about the dead start test, only the run and temperature test.

    Also with the Koford you could build a break in jig for falcon type motors and you could run more than 8 or 9 and not have any problems with it shutting down.

    Gestin,
    I rate my power supplies by what the Transformer is rated at 12 volts. I'm not sure how Koford figures his amp rating.

    Thanks for your feedback guys.
    Much appreciated! Also great to have Mr. Wright Way himself here.

    Les, for the purpose of slot car racing, testing, break-in, etc... Do think there is any reason to want to go above 8amps on the power supply? Are there times when the 8 amp limit is approached in the normal course of the hobby where the power supply would just kick out? I guess I am really asking how important is it for this hobby that a power supply can operate over 8 amps? Generally, do slot cars operates in the 3 to 6 amp ranges and occasionally you will see 7 to almost 8 which is really just indicating there is a problem with that motor or there is significant resistance somewhere causing the high current?

    Really appreciate your chiming in here.

    You might need a tad over 10A when running G7 Motors, else not.

    Thanks for your input zipperi.

    If I need 10amps for G7's I guess the Koford is the choice.

    Unless Wright Way makes a unit higher than 8amps. Anyone know?

    Thanks guys.

    As a G7 driver Les may tell how his power works with those - I suppose it should be powerful enough. The worst power suckers are G7 qualifying motors, the race ones usually suck 7 to 9 amps max when starting to break in.

    The only time that "I think" you may need a 10 amp PS, is if you plan to run you stuff in at 12 volts.
    My 6 amp will put out over 15 anps at 2 volts. I have not had anyone complain about not have enough
    amp to run any of their gp 7 motors.

    Many racers use their travel power supply to run the RC motors on their tire and armature grinders as well as just testing the race motors.
