Ideally a wall wart, but MUST have an output of 6 volts AC and provide at least 1 amp current.

My google fu is failing me. EVERYbody wants to sell me a 6 volt DC adapter.

I've beat Amazon and Fee Bay to death and can't find one.

Google "6VAC transformer", several wall wart options.

I did, multiple times and never saw that. It's perfect! Thank you.

EDIT: And reasonable shipping too. It DOES exist!

Damn. What search phrase did you use?

Looks like you found your items. But I have to know,. What takes 6v AC???

Christmas decoration. Angel with fiber-optic wings and a rotating color disk. Motor and bulb both run off 6v AC. Somebody was tossing it because the bulb was blown and BiL grabbed it. Didn't get the power supply and the only 6vac wall wart I had in my junk box was only 300ma and didn't have the poop to run the bulb and the motor.

Pro tip.

Most wall warts are half wave rectifiers. If you're desperate, buy a 6VDC wall wart, open it up, cut the diode out or jump it with a piece of wire and you'll have 6VAC.

What about the filter capacitors and the RMS thing? What I’m saying is the output of the transformer, the stepped down AC signal, from a 6VDC wall wart isn’t going to be 6VAC. Or am I wrong?

You're wrong. Note there are no filter capacitors in the schematic and if you've ever opened up a few wall warts, you'll find there are none inside.

And the 6VAC is going to be 6V RMS if the wall wart has been labeled correctly. For alternating electric current, RMS is equal to the value of the constant direct current that would produce the same power dissipation in a resistive load.

It's the little plastic box that plugs into an AC outlet and has a power cable coming out of it that plugs into something to charge or provide power for.

Here's a pic of one:

I may be wrong, but I think it's mainly confined to people who work in electronics one way or another.

Actually most (but not all) wall warts for the past several years are Switch Mode Power Supplies (SMPS), and the circuit is far different from the simple schematic that was posted. You will note that the picture that LB-FLash posted of a wall wart even says "Switching Adapter" right on it. So be careful what you try to buy. You will note the SMPS Wall Warts are generally lighter than the traditional step-down transformer type of yester-year, FWIW.

By the way, I only buy UL (or other NRTL such as ETL, TUV, etc.) approved supplies and, I don't modify them, or suggest that others modify them. But that's just me, I'm a bit particular when it comes to that stuff.

Ok, so 6 VAC @ 1 amp. But what the heck is this for anyway? Knowing this might help to know just how clean the AC has to be, as well as other design factors. Powering, for example an incandescent bulb is far different than some sensitive circuit, so it would help to know.

By the way, Sock Eating Golden: Good to see you on this thread. Seems like it's been a while, but I don't read all threads.

Not true. Most modern DC output wall warts are little switching power supplies.

Never seen a switcher wall wart. Even all the Apple battery chargers and others I have to charge cell phones are half wave rectifiers and I buy new, higher output ones on a regular basis.

For the larger loads, switchers are probably indicated but not for smaller loads as they'd be cost prohibitive.

If they're very light weight, they're switchers if they aren't, they're half wave rectifiers.

Lastly, the OP asked about a 6VAC wall wart and switchers don't do AC, they only do DC

The rules have changed. SMPS's have become cheap, even for smallish loads. The solid state components plus smaller magnetics of a SMPS are cheap, and a pallet of SMPS is smaller and weighs a fraction of what a linear supply would, which is a factor.

Plus switchers are kind of handy because the input voltage can be like 100-240 VAC 50/60 Hz without some small switch on it, etc. Therefore you get world-wide use with the same circuit, although the plugs still differ, obviously.

Interesting read. Really shows the quality that Apple engineers into their products. Also supports the claim that Apple chargers really are better and better for your equipment.
