The Wurlitzer Electric Piano / Re: Noise in the amplifier.
« on: July 09, 2019, 12:17:13 AM »
Hello again.
 Yesterday I received my old amplifier from my wurly 200. A technician reflowed all the welds and it worked ..... now there is no more noise and buzzing! It has been a great improvement !.
Everything I did:
- Check the electronic components of the amplifier.
- Reflow of the amplifier welds.
- Remove the ignition light.
- Check the cables of the ground points.
- Place the reed shield bar.
I hope this works for other users.
Greetings and thanks for the tips.

Hello again.
  Yesterday I spoke with the technician and explained the work. He told me that he can do it. He usually works with analog synthesizers and the reflowed procedure he usually does.
I'm lucky that he's in my city, he works very well!
I know he's going to do it right!
Thank you very much for your advice and help.
Greetings.

Hi from Spain.
Thanks for your answer!
  My soldering iron and my welding skills are basic so I will take the amplifier to a technician to check the welds.
I've worked a lot on this piano and I have to try to make the noise disappear, it's the most important thing!
I will also check the ground points.
Thanks for everything.

Hi, beginnersluke.
 The reed bar shield already I have it and I have verified that the noise comes from the amplifier.
I will start to change the electrolytic capacitors.
Thanks for your answer.
Greetings.

The Wurlitzer Electric Piano / Noise in the amplifier.

Hi from Spain.
  This is my first message in this forum. I need some help. Thank you!
Well, I'll tell you: I bought a 200 wurlitzer and I'm working on it to have a great piano.
I have already regulated the action and I have also restored the wooden base of the piano. The keys are also clean and regulated and the reeds are in their tone.
The problem is the amplifier, there is a lot of noise and interference. Also if I touch the amplifier with a wood, it makes noise.
I have verified that the noise comes from the amplifier not from the bar reed.
What I would like to know is that changing all the components of the amplifier will remove the noise. This is my question.
I have little knowledge of electronics, I can solder and measure resistors, diodes ..... but little else.
I await your answers and greetings.
