i am looking to purchase a resistor wheel does anybody know of a good place to buy one?? i have looked on all the stores listed on this wonderful site and found nothing except potentiometer which wont help because the increments are not labled.

I hadn't checked for these in a while. The one I got was from GC electronics. I checked their catalog and searched for wheel:

Resistance Wheel Helps select resistors for any circuit. Color-coded insulated alligator clips attach easily to circuit and easily readable dial, then indicates resistor value when rotated. 1/4 watt, 5% resistor values (5 W1M), 100 V max. Cat. No. 12-0104-0000

If you happen to be in Fresno/Clovis California Sparky's Elentronics should carry them in stock (that's were I got mine when I worked there).

There's also elenco:

This looks like a dial setup but it says that the resistors are incremented in common values. The dials could be switch box type dials. If they are multi position dial switches that explains the cost (~$27).

BTW they also have a capacitor box. I think I might be needing one of these, all though there is some problem with leads and capacitor boxes (the leads can interact to change the capacitance in the circuit).

The nice thing is that if you blow a resistor there's a good chance you can replace the resistor, so long as the switch contacts weren't damaged as well.

These folks are in Illinois, I went down there with a friend to get one of their temperature controlled static safe solder stations.
