[quote user="MisterBeasley"] The bridge rectifier is the 4 diodes assembled in a diamond pattern.  I would suggest simply buying a bridge rectifier when you buy the resistors and capacitors. <div style="clear:both;"></div> [/quote] Thanks for the tip.  I see several bridge rectifiers listed at my LHS website...from 140 ma to 1/2 amp and 1 amp.  Are any of these values correct....but more importantly, where and how in the circuit does the bridge rectifier go????[D)] [quote user="retsignalmtr"] There is a CD unit called the Snapper......... Uses the AC accessories power from your power pack, puts out DC to throw the machines. Easier than building one. <div style="clear:both;"></div> [/quote] Thanks for the tip.  I looked it up and it is now $29.  Well, the price list for the part for making one is about the same, so I think I will order this one.  I have always used a separate circuit with an additional power transformer to power my snap switches.  I imagine I can just insert the circuit between this and the barrier strip that sends power out to all the switches.
