workbench Q's

If you simply want to do testing I suggest something like  a 50 amp power supply with a permament source unit and a board containing terminals for easy hook up, they should consist of power ground speaker and RCA terminals. Other wise every thing else is just personal preferance. You could also add a volltage and ampreage gauge. Note that the 50 amp supply can be substituted for a smaller one if it is going to be used strictly as a test only station. I have a 50 amp supply but I use my bench for music in the shop and generally have some misc amp and sub hooked up as well. If you wanna go ghetto you can buy a battery charger and hook it up instead of a power supply, it provided the same basic end result, and are generally less expensive. Thats what I woulda done had I not had an Extra power supply hanging around from an old board.double-secret reverse-osmosis speaker-cone-induced high-level interference distortion, Its a killer

You basically just need an AC to DC power supply. Anything from 20 - 50 amps should be fine for testing stuff.. Radio shack has a decent selection. Mike

As long as its a battery charger capable of putting out enough voltage on a medium or high setting, you dont wanna run it on the start setting for that long, refer to the manual for the charger.double-secret reverse-osmosis speaker-cone-induced high-level interference distortion, Its a killer

keep in mind it will be unregulated voltage which as a rule is never recommended.... spring the few bucks to buy a proper regulated power supply as was suggested to you......Kevin Gerry

For my own personal knowlege, what kinda affects is having a regulated power supply over an unregulated power supply on a test bench gonna do?double-secret reverse-osmosis speaker-cone-induced high-level interference distortion, Its a killer

unregulated, voltage spike, and as said before.   Most electronic items run on smoke, when you let it out they quit working2009 0-1000 Trunk WR 154.0DB 2009 1001+ Trunk WR

Good one Jeff! I like to tell the customers that if they let out the"Magic Smoke" we have to put it back in before the unit will work.BigDog

as mentioned the possiblity of voltage dropouts or worse, spikes... also, the nasty 60 cycle hum you get from most cheap battery chargersKevin Gerry
