Yes, that specific spot is meant for an AC cord, which has + and - leads and a ground as well. Like the plugs you plug into your wall - three prongs. That's why there's two spots.

There's also a spot for 15V DC, which is probably what you should be using unless you know how to properly work with mains voltage.

Because this isn't a Madbean project, I've moved you from the Tech Help department to the open discussion forum.

The road rage is capable of giving you 18-24V DC, but at a limited mA output. Using an LT1054 would give you approximately 18V at approximately 100mA.

About the two pads, since I don't know much about the NeoVibe project it's very hard to answer your question. Perhaps you should post some links to the project documents. Depending on where the project is from this may not be the best place to be asking about it simply because we will likely be unfamiliar.

Glad to help.

Your voltages look fine, which is a bit confusing considering the issues.

Essentially, it's looking to me like you've got something funky with your wiring or with your part values/soldering in there. I know you've said you've gone over the board looking, but if the problem persists you have to face the fact there's something in there that's fishy.

I would go over R19-R23 and C14/15 with a fine tooth comb. Check for solder bridges especially. Check your wires aren't faulty/broken inside. Check your part values, and don't assume that they're correct because of the markings. Check for solder bridges again.

That's all I can really suggest. Pictures might help us because we can also check your values and look and see if we see any soldering issues.

Jacob

The cap type should have no difference.

Do you have voltages?

Jacob

[4558]

yes they are the same.

do you mean 4558?

Jacob

I'd love to see either the Tweed Bassman or Blackface Princeton end up done like this. I'd use it as a preamp for recording purposes if I had something like that.

Jacob

nice...

Jacob

No, I use the word zero.

Also, it really bothers me when people use the word 'oh' for the number 0. the numbers "306" is not "three OH six" it is "three ZERO six."

This is a weird thread
and it should have more haikus
pedals are so fun

Jacob

In Canada, it's even worse.

How do you pronounce the letter "Z"?

In Canada it's "zed".

Jacob

my guitar sounds plain
when no effect pedals used
madbean is my friend

The last man ever to successfully rock a cod-piece. 

What are you talking about? I wear one everyday!!!







kidding...

Jacob

Here in Canada those things are found at Canadian Tire.

Jacob

Sure,

What steps have you taken so far? Have you read the sticky thread "rules for getting tech help"?

Jacob

I love the finish on that one man!
