Okay, the main noise is gone. There is a wire from the reeds rail to ground that had a cold solder point. When the case was moved, that connection broke, which led to the loud noise.

There's still some high frequency crackling noise, which gets louder when I hold my hand close to the wire that comes from the pickups.

With the lid above the reeds in place, there's just some crackling high frequency noise left.

There's still some "static" when I press the keys, or tap the case.

I'm still thankful for further advice!

I have just bought a Pianet CH. There was hardly any noise when I tested it at the former oener's place, and although all sticky pads have disintegrated, the reed sound was clean and clear when I plucked them with a guitar plec.

At home, I tested it, and there's loud noise, like interference and static. The sound of the reeds is still somewhat present, but the noise is far louder. Furthermore, when I tap the Pianet's case, or even take a step on the wooden floor (which sinks in a bit), the noise jumps to another volume. Tapping the case or moving the keys is amplified as noise. It seems to be very microphonic. And bending the case slightly lets the noise change volume, as well as "content", as said.

Where does that come from? And what would you check first?

Does anyone have the PDFs from the hohner-xyz websites? They are all down, and there's not much info left on those sites.

Thanks!

I've got a strange problem. There is almost no sound in the newly acquired 140B, but the noise in the volume pot gets amplified (so the amp does its job), and when I put my finger across a reed and the pickup, I hear loud pops.

I've read that there can be no sound when a reed shortens with the pickups. But then my "finger shortage" would make no difference, correct?

The reeds seem to be quite wide for the pickups, there is virtually no gap on either side of the reeds. And at least one reed is vibrating against the pickup. Maybe they are incorrect reeds? Was there a model with wider reeds than the 200/140B etc?

What troubleshooting procedure or steps would you recommend?

Thank you!

If anyone knows of an Elepian for sale in Europe, please let me know!

Hello,

since some of you have heard the Musser Ampli Celeste, may I ask how it sounds? Is it like an "amplified Celeste", or does it sound similar to a Fender Rhodes, a Wurlitzer, an Elepian, or a Hohner Electra Piano?

Even better, do you have some sound samples? Is there a Wilco tune on which I can hear the Musser?

Thank you!

Yes, please report back about how it's going with the new batch. Thank you!

This thread has a tremendous amount of valuable info! Thanks to everyone! This should be a sticky in the "Pianet" sub-forum. ;)

And if anyone has schematics etc., I would be very interested. Haven't found a place in the signal chain from where I can route the signal off to an external amp yet. The places I expected to work didn't.

For all future reference (whoever might be interested in the Baldwin EP-100): The Baldwin EP-100 is not an electro-mechanical piano like the Fender Rhodes, Wurli etc. It is purely electronic. It has an interesting tone (a bit cheesy, but surprisingly meaty and convincing for an electric piano of that age), and it is touch-sensitive. You can change the volume at a trim pot on the back, lower left side.

I don't intend to spread more rumours, but from what I can tell from youtube videos, it sounds a lot like the later Kustom 88 piano, which was made by Baldwin, minus the tremolo and the bass slider. The treble slider seems to be kind of available in the damper pedal - if it is pressed, the piano sounds like the Kustom with treble all the way down.

The oval loudspeaker in the EP-100 is surprisingly good for its size.
