damage to belton brick?

[bagudan]

Hi.
i´m a fool. I quickly wired up a digital reverb, from a vero layout I found. But I misplaced an 47uf electro cap (c5 from this schematic: http://www.generalguitargadgets.com/pdf/ggg_verb_sc.pdf) Soi unfortunately. There was 9 volts everywhere for a while. I have now corrected the layout, but there is no sound when engaged. Have I fried the expensive belton brick?

The brick is supposed to take 5.5V tops so there's a good chance that you have. You need to use an audio probe to make sure that your signal is making it as far as the brick in the first place.

thanks. i´ll give it a try

Check the output voltage of the brick with a DMM. If it is broken then shame on them. Imagine connecting a positive and negative ground pedal to the same supply with a daisy chain. Say classic Fuzz and any other pedal. That is a very realistic scenario that would simply short out the supply.

Hmm, you give me an opportunity to show off my pedal power supply again: http://www.diystompboxes.com/smfforum/index.php?topic=85925.0
This would have never happened to my supply. It can be shorted indefinitely. And it only has 5 extra components than necessary for supply regulation. That just shows that even expensive gear might not always as good as you expect.

I think you've misinterpreted this. The Belton brick datasheet states that it needs a 5V supply, the GGG schematic includes a 5V regulator to provide this from 9V. bagudan made an error building his circuit that meant that the Belton brick got supplied with 9V.

You can't blame Belton for not designing in protection for end-user assembly errors, same way that you can't blame a car manufacturer if someone fills the petrol tank with diesel.

No, I realize I have only myself to blame. This is by far the most expensive component I´ve ever toasted;)

Hmm, I thought it was the DC Power Brick! (Pedal power supply) That one should be protected against short circuiting.

You are right, the Belton Brick does not need that! Excuse me not checking well enough which brick you talked about

Well, I know it´s been 6 months since I started this thread, Just wanted to let you know that a belton brick can survive 9 volts

had this project lying in the drawer for half a year, and finally got to debug it. I´m to embarrassed to let you know what a stupid mistake I did in the wiring of this pedal;), but anyway. The brick had 9 volts du to an error I made in the layout, and its working perfectly ´(with 5 volts) now.

Glad to hear you've got it sorted.

No need for embarrassment, everyone can goof. The hard part is facing the consequences of a mistake and getting your attitude back in adjustment to correct it. Good work.
