I bought a Yamaha PSS80 at a yard sale, and discovered that it did not have a sound output jack. Some later versions of this little keyboard may have corrected this problem.
This video shows step-by-step how to modify a Yamaha PSS80 “Portasound” electronic keyboard by installing a direct sound output jack for patching it into mixing boards, computers or any audio device. While this instrument is not a true synthesizer, it has some unique synthesizer sounds that can be a very useful part of the electronic musician’s toolkit. This technique can be used with any keyboard that has speakers but no direct sound output jack.
The modifications require a few simple tools and one 1/8″ non-circuit breaking mini jack, available at Radio Shack.
When modified, the Yamaha keyboard is able to patch and play music directly into audio devices, including the line-in of a computer, with no loss of sound quality. This allows one to use the unique synthesizer sounds in a variety of ways, mixing it with other tracks of a music composition in a sound editor, for example. At the same time, it will play through its own speaker, which in some cases can create a modified “stereo” effect.
The music performed in this video is Yamaha’s own “demo song” built into the little keyboard.

You need a “cut off” jack for this, and you can get them (stereo only) at Radio Shack. The wiring is different however, and the disadvantage is that if you are recording from the Yamaha through the jack, you can’t hear anything.

thanks a lot for …
thanks a lot for the info. i was succsessful in my first attempt ever with modifying electronics. i’m just wondering if theres any way you could make it so that once you plug something into the audio out hole the sound to the speaker stops? any suggestions

A 3-conductor will work, but you only need two of them – ground plus either the tip or the short sleeve.
To make it compatible with 1/8 inch stereo plugs, you could jump the tip and first sleeve connections together for one speaker wire(strip a bit more wire and run it through both tabs), and the ground with the other. That way, if you use a stereo 1/8 plug, both channels will get the same signal instead of just one channel.

would a 3-conductor 1/8″ phone jack work? it has the same input but the jack has 3 tabs for sottering

i just got this electric piano today at a flee market for 5bucks ama try to do this to it

thank you very much …
thank you very much, I want to do the same mod, however cut the speaker off for live use, I am going to do this with a casio pt-10.

Yes capacitor voice …
Yes capacitor voice, you are on the right track. You have to use a two more wires.
Wire both leads from the amp to the jack. (one for ground, one for the tip)
Run additional wires from the ground and the part the tip circuit breaker contacts to the speaker.
Now when you plug into the jack, the amp power will go to the plug but cut off the speaker.

If I want the line …
If I want the line out to kill sound from the speaker, would I purchase a ‘circuit breaking’ mini jack? And, are the connections the same?

Thanks. I used to have a C-64 and a program by Broderbund called Music Shop. It was fun.

Very well explained! I like the way the Keyboard sounds, almost like a C64.

Thanks! I know you meant you were amused. Making these videos and soldering at the same time is like trying to chew gum and walk at the same time. Takes practice.

Great help for new cricuit benders also it made me chuckle when you dropped the stereo jack
(I dont mean it in a mean way)
Thank you so much

I really liked your channel and this video. If you need any help getting this video exposed I use a site called tubeviews.(net) It has really helped like 20 of my main videos get to the top in position. Its nice.
THIS WORKS! Its amazing.. THANK YOU SO MUCH DUDE!!!!!!

Thank you for this video. I just found one of these little guys and now I can prepare it for circuit bending. This is great!
