Title: where to order wall warts ??
Post by: buildafriend on February 13, 2011, 04:34:10 PM
i live in new jersey on the east coast of the U.S.

i need 2 wall warts but i don't know where to order.

Input:
120 VAC
60 Hz
23W

Output:
16 VAC
1000mA

Also need

input 120VAC
60Hz

Output 12VAC,
anywhere from 500mA to 1000mA will work.

Check your local thrift store. Seriously, a lot of them will just have a bin of miscellaneous wall warts for $0.25-$1 each.

No thoughts on where to order, but I would ask what you are going to use them for.  The output from typical wall warts is usually not the best and it can create problems (hum, hiss, white noise, etc) down the line.  OK for charging batteries, but not ideal for music.

If the pedals you are going to use these with have good filtering built in, then go for the thrift store variety.  If you want something that puts out a clean, consistent voltage, then you should consider building your own.  There are many kits and/or schematics available.  You can easily build a power supply with multiple outlets to run several pedals.

These aren't wall warts in the way we typically think of them, they're AC, so hum, hiss, etc won't be any different than the original unit because all of the power filter circuitry is inside the device that's using these.

I'd try eBay for these.  Just pop in the secondary side information and see what comes out.

I guess some people don't know I stock these. Not a huge selection, but best list I could put together of "most commonly used":

Unfortunately, the 12 VAC model that I have is a little pricey because it's an OEM replacement that I don't import directly.

Try Mouser.com...they have an enormous selection, and they are pretty easy to deal as long as you have a part number.

they had one that was 12V 400mA!! rr so close.

If that's the chassis, screw a wall wart, put an IEC socket in it, power it from the mains, and mount the transformers inside the chassis.  If you have problems with them coupling to the circuits, put a metal cage around them that is grounded to the chassis.

That's where I got most of the ones that I use, including 12VDC types. With the LM317 adjustable voltage regular built into my pedal boards and set at 9.5V, I can use whatever wall wart I want with it and not have to worry about it. I just change the plug as necessary.  Happy camper here.  :icon_razz:

I have bought cheap thrift store wall warts that overvoltaged quite a bit when not loaded much (I managed to fry my old Sabine Tuner), so I would test the voltage of any wall wart (under load) before hooking it up to my pedals.

Yes, good advice. Or use a voltage regulator which bumps it down to the voltage you need without worrying about damaging your stuff.
