yamaha DD-9
« on: September 15, 2009, 04:50:50 PM »
Hi all! (first post got to be done  ;D)

I am a novice at this, just started, i've successfully bent a yamaha pc-55 and a grandstand talking whizzkid (sans teaching cards). Both are much fun.

I just took delivery of a DD-9, first thing i do is open it up to find the componentry facing me rather than the circuit track. It also has an annoying on/off switch that breaks the contact when you try to flip the circuitry... I found some possible bends on there probing with my croc clipped screwdrivers and now the first effect pad and more annoyingly the rhythm control wheel no longer function?! Have I made an enormous schoolboy error? Is it recoverable? I've not even plugged in the iron yet!  >:(

Any help gratefully received.  :)

If you're just turning it off then back on, try taking the batteries out. If that doesn't work [I know I've said this a billion times] just let it sit for a week or so without any batteries in it. I've had machines I thought were done for come back to life a week or two later just because I let them sit there. Hope that helps! Welcome to the forums!

Cheers dylan :)

I'm using the dc converter, turning it on then off has had no effect. I've heard that leaving it for while helps before- allows the caps to lose their charge?

It's just a bit of a pisser, I've barely had the thing 30 minutes!

Oh man 30 minutes? That blows. A week or two ago I was trying to bend one of those megaphone voice changers and fried it almost as soon as I got it out of the box. I haven't done anything to it since then (been at college) so I'm hoping that when I go back to it it'll work.

You can discharge the caps just by shorting their pins together, you don't have to wait for them to leak their charge.

i've just been around and tentatively done just that- no change. what i did notice is that there are small diodes next to all of the inactive parts. is it possible i blew these?
