humanflyz Posted May 20, 2009 Report Share Posted May 20, 2009 I recently sold my Stello DP200 to laxx, and upon taking delivery, he told me that there is a problem: the headphone jack does not work. He tells me that he feels no physical resistance when plugging the headphones in, and there is no volume. The Stello is supposed to mute the pre-amp outs when headphones are plugged in, but laxx tells me that even with phones plugged in, the pre-amps still work. My first thought is that in the shipping process, the headphone jack became dislodged from the chassis such that it no longer grips the headphone plug completely. Does this sound plausible?

laxx Posted May 20, 2009 Report Share Posted May 20, 2009 I figured I contact Mike before making any posts about it. I'll be picking up a 2mm allen key to take the chassis apart tomorrow and see if there's anything physically loose. Hopefully it's a simple problem to fix.

Pars Posted May 20, 2009 Report Share Posted May 20, 2009 I don't know what kind of jack this uses, but yes, you should definitely feel resistance as you insert the plug into the jack. On normal Neutrik switched jacks, when the plug is inserted, it lifts contacts off of the switched set of contacts used for preamp or whatever, thereby taking them out of the circuit. The fact that the pre outs still work would indicate that the plug is not disconnecting these. I would think it should be an easy fix.

laxx Posted May 20, 2009 Report Share Posted May 20, 2009 Got the allen keys earlier today and will be openning it up tomorrow. Quote Link to comment Share on other sites More sharing options...
laxx Posted May 21, 2009 Report Share Posted May 21, 2009 So I openned the chassis up earlier and this is what I found. (I unplugged the jack that's mounted on a pcb board connected to a 4 pin thingies) How would you go about fixing that? Part of the jack is on the front panel (glued on) and I don't know how someone would be able to get it out to put in a new jack. Any help is appreciated.

laxx Posted May 21, 2009 Report Share Posted May 21, 2009 I have no idea. I just figured it's glue. Quote Link to comment Share on other sites More sharing options...
Pars Posted May 21, 2009 Report Share Posted May 21, 2009 I assume the panel is metal? Aluminum? Steel? You could probably get most if not all of it with something like an xacto knife or the like. Possibly have to carefully drill it out. Or use a ream, again carefully. That jack doesn't look familiar. Was it completely broken apart like that when you opened the amp? That would explain the no resistance. But yeah, the entire jack needs to be replaced. Quote Link to comment Share on other sites More sharing options...
Mister X Posted May 21, 2009 Report Share Posted May 21, 2009 It kind of looks like this one---> SJ-630X - 6.4mm right-angle stereo jack CUI Inc. (can't tell from your picture if it is threaded into the hole in the panel) I think I would phone them and see what the damage is if they maybe will send you a replacement for it.

laxx Posted May 21, 2009 Report Share Posted May 21, 2009 Looks to be like super glue/crazy glue. I didn't get the front panel off because it was a lot of work (having to disconnect a bunch of stuff), so I'm not sure how it looks from the front. It was completely snapped off when I opened the case. All I did was unplug the 4 pin from the pcb board. Quote Link to comment Share on other sites More sharing options...
Mister X Posted May 22, 2009 Report Share Posted May 22, 2009 Heh, I really need to learn to pay attention. Stello not Lavry.... :palm: :palm: Quote Link to comment Share on other sites More sharing options...
n_maher Posted May 22, 2009 Report Share Posted May 22, 2009 I would contact Stello and see if they are willing to send you a new jack already mounted to the small daughter board pcb. From there I'm sure you can find a way to get the old material out and get the new one in. Kind of disappointed to see that the jack is just glued in though, that's pretty weak.

Pars Posted May 22, 2009 Report Share Posted May 22, 2009 You would have thought they would have made the PCB larger and mounted it securely and use that to support the jack. Gluing it in as Nate said is pretty lame and bound to fail sooner or later. Quote Link to comment Share on other sites More sharing options...
laxx Posted May 22, 2009 Report Share Posted May 22, 2009 Already emailed Stello and they are sending a replacement jack from Korea. They said I should be able to do it easily on my own, so it makes me think it's not glued. Maybe if I take the front panel off, there's nut/washer holding the jack in place.

n_maher Posted May 22, 2009 Report Share Posted May 22, 2009 Can you take a picture looking down on the top of the front panel? I'm not sure how they could be using a hidden mount unless there's a false front of some kind. Quote Link to comment Share on other sites More sharing options...

That would make more sense if there was a panel behind the front panel that it was mounted to via a mounting nut. That is how my preamp is done for the switches, pot, etc. That jack that MisterX pointed out looks like it could be a contender other than the lack of gold plating.

laxx Posted May 22, 2009 Report Share Posted May 22, 2009 The front panel is mounted to the black chassis by 6 allen bolts. I didn't take them off because I'd have to disconnect a bunch of other stuff before getting to all the bolts though. I can take more pics this weekend.
