Well I'm looking to make one for benchwork, and I came arcross this:
**broken link removed**
I think I can find all the parts...except I cannot find a 24vac, 3A transformer. I am going to be plugging it into a standard 120Vac outlet.
I don't think I will need the meter either...If I were to use a meter, it would be digital, however I dont want to spend money on a digital meter. It will be easy enough to hook a DMM up to it to adjust my output voltage.
Would there be much difference between any old trim-pot, and the Bourns brand that they use? I'm going to guess that it is just more accurate.
On a side note I would like to add that MultiSim seems to always be missing something. I have yet to actually simulate anything outside of school work with it due to not haveing the components.
In this case, the LM317 is nowhere to be found in multisim...
