Looks like someone may have spilled some liquid at some point as there is rust at the base of a few of the front rail pins. I am wondering if anyone has any suggestions on methods to remove and prevent the rust from returning?

I'm thinking of getting a dremel with a wire wheel to remove the rust. Is there an oil/product I can apply after to prevent it from returning/spreading?


Any help would be much appreciated!

With the bump resting against the hammer in stop lock position, it is right at the edge of the pedestal.
This is the case throughout the whole keyboard. 

In all the videos/photos I can find online, the bump is able to be placed further back than that.

When applying the felt, it seems like I would have to wrap it around and onto the vertical face of the pedestal in order to cover the whole bump.

 
There is 1/16" between between the back of the hammer and the back of the pedestal.
- Are the backs supposed to be flush together? Does that difference in pedestal/hammer relationship have an effect on responsiveness?

What are my options here?

- Just do the mod at the very edge?
- Do the major surgery of moving the action rail and harp supports back so that the back of the hammer cams are flush with the back of the pedestal, giving me an extra 1/16" to play with?
Doing so, I would then have to redrill the harp because the strike line will be off right?

Is there something else I am missing here?

Any help/input would be much appreciated!

I am currently restoring a Clavinet C and have run into an issue.
Please forgive me as I am not extremely well versed in the field of electronics. However, I am always trying and willing to learn and would very much appreciate if anyone has any help they can provide!


I purchased and installed replacement DC jack plate from Vintage Vibe.

I was not getting any sound whatsoever from the unit using battery or PSU. Only a pop when turning it on.
I tried cleaning the switches, disconnected both pickups and checked their continuity (176+205 ohm).

After reconnecting the pickups, I noticed by accident that if I reverse the battery leads I get good tone from both pickups in all switch orientations, however it comes with a loud, constant scratching noise in the background. Here is a link to audio example https://soundcloud.com/rick-demo/clav-c-reverse-battery-leads-audio

If I put the leads back, no sound again.

Does anyone have any idea what would cause the unit to only work on battery with reverse battery leads? And why the accompanied noise would be so loud?

Is it likely that the preamp components have been damaged due to the reverse battery hookup?

Here is an image of preamp and my PSU, that is the correct PSU right? 9V DC 300ma center negative?

I have just acquired a D6 and it sounds amazing. The previous owner had replaced the strings/re-yarned, replaced hammer tips and bushings. The only issue I'm having is that a few notes aren't sounding fully in certain pickup modes. B3 and A4 are very quiet only when C and A switches are depressed. D1 is very quiet on all settings, except for C and A mode. I'm almost certain its not a hammer strike alignment issue since they sound fine in the other pickup settings. Acoustically, when I play the notes they sound just like the others.  What's going on here?

Hi everyone. I am looking into buying a 200a from someone. I had them Facetime with me since he lives in a province over from me. Aside from a few notes having short decay and a couple sticky keys when sustain is pressed, we noticed that there was a feedback issue when the sustain pedal is depressed. Not only being triggered by notes, but can be triggered by simply pressing the sustain pedal and holding it. I guess the sound of the reverb from the dampers releasing are enough noise to start a feedback loop.

Is this a common problem/somewhat easy fix?
Any idea as to what could be causing this?

Should I avoid making this purchase because of this?


I appreciate any "feedback" any of you may have,

Thanks

A note in the mid range of my stage 73 is giving me an odd "reverb" sound. Im clueless as to what is causing it.
I'm almost positive that it's not the damper because even if I stop the tine with my fingers I still get this reverb that lasts for a good 4 seconds.
I've tried muting all tines/tone-bars near the bad note as well and still theres this "reverb".
I also tried tightening the tone-bar screws thinking maybe it was a bit loose but that's not the case.
What's going on here?!

Any one else unable to get onto this site? It hasn't been working for me for a good month.
I get a 404 error with a sad face every time I go on.
What am I doing wrong?

Thanks

So I started to take my tone bars off of my stage 73 and I noticed this weird looking "goop" on my ground strip running under the tone bars on the harp.
It doesn't seem to be affecting my ground but it doesn't look too nice.
Does anyone have any idea what this stuff is and if so, should I get rid of it?
If I were to get rid of it what should I do/use?
Any input is appreciated.





Thanks
