The Final Act

[SparkyCal]

So, I have managed to build an overdrive pedal, complete with a real stomp switch and a LED that lights when the effect is active.

The only thing left to figure out, is how to include an A/C plug that, when plugged into an adapter, cuts off the 9 volt battery power, and runs on the AC adapter instead.

I guess I need to find a schematic for it. Also, does anyone know what the female plug is called that would sit in the pedal, so that an AC Adapter can plug into it? I'll need to buy those and wire them in.

Thank you

That is very simple and nicely explained here.
Although they call it an "AC adaptor jack" and I call them DC barrel jacks.

You probably want to use an AC to DC adaptor as all the conversion and rectification is done for you.
An old router 9V or 12V adapter will work just great.

if not, does anyone know where on Amazon I can find them?

thanks

In case your strictly Amazon for some reason

 

[SparkyCal]

Thank you VB. I will order the Amazon ones for two reasons

1. Digi keys looks great but last time I tried ordering something, I was facing a $20 surcharge on a $12 order. I should try it again though

2 I own Amazon stock so always try to support it

We need to get you hooked up with a good Canadian parts house.
I find some stuff on Amazon.
It's better than RadioShack ever was, but still not 420 pages of opamps good.

Newark Canada might be your jam

Amazon sells clothing and a few cheap electronic parts with no specs and frequently they do not even know who made the junk.
I buy most reliable electronic parts from Digikey or Newark and if I order before 8:00PM it is delivered to me in Canada the next morning.

 

[SparkyCal]

I will look into Newark. Digi keys is not an option based on delivery fees

if allied didnt have a spaghetti site, they'd be my go to due to location ... anything i order will be in hand the next day, even at the cheapest rates.
You, being on the other side of the northern boarder, probably couldn't justify most hobby quantity orders from most US houses.
You DO however, have some really decent tube shops when you evolve that far.
In the meantime ... Amazon turned out to be good for PT2399's .... You might look into those chips yourself.
