I bought a pair of Troller powerpacks,both like new,didn't realize the first one I got had oddball knobs on it.Anybody got any Troller,or better yet,MRC powerpack control knobs?
Is there anything special about the factory knobs? It is probable that the factory ones were broken, and were replaced with generic knobs from an electronics supply store. Perhaps the one doing the replacement was, as are many model railroaders, very cheap, and made poor choices of replacements. You should be able to get replacements from either a local supplier if there are any, or an internet retailer for very little money. The knobs have no effect on the operation, unless they are very small.
Lou D, I'm not familar with a MRC Troller power supply. However, if it's a crank type knob with a spinning handle, like was used on the metal cased Throttlelpack, eg. the 501N. Then I think that it was/is a MRC exclusive. The knob may have been made for MRC, by one of old line US knob manufatures like Demco. Some of the newer plastic case power packs also used it. I would email or call MRC. I hope this helps. Regards, Charley.
I'm aware of that,Radio Shack has lots of "knobs"....But,I really like the MRC style knobs and I already have two,or I could keep it original with two Troller knobs..
I would suggest contacting MRC directly MODEL RECTIFIER CORPORATION 80 Newfield Ave. Edison, New Jersey 08837 Phone: 732-225-2100. Troller went out of business years ago, so good luck there. Might try the Bay..
OK, your heading threw me off. I don't know the history of Troller. Did MRC buy them? Anyway, if you need knobs try; http://www.reidsupply.com/, http://www.mscdirect.com/, or http://www.mcmaster.com/, more knobs than you've ever seen, lots of cool tools too. Charley.
Be careful with Troller powerpacks. My memory is foggy on this, but I believe that is the brand the cooked a lot of can motors in days gone by because the pulses produced in the waveform can go quite a bit above 12 volts, zapping through the insulation coating on the armature coil wire. Q-car Company, which used Sagami motors to make O-scale power trucks for trolleys, would not warrant their products if you used this controller. Rich K.
