I have one that sat too long at someone else's house. It's a great keyboard and VERY powerful but you CANNOT y the two channels together. You must run them separately or you risk burning the circuit board. It is true stereo and instruments are weighted according to symphonic orchestra placement on stage. My information is that it can run on six D cell batteries but today I can't get six in the slot. I can't tell if there's an old battery stuck in the bottom of the battery slot. Since I can't just now lay hands on the correct power supply I may not be able to see if it still works. Someone may have used a Y cord to run both left and right channels into one,cwhich causes the board to hum naetily, and act unhappy, so it may be burned out. I have a newer one but hate to give this obe up until I know it's really dead. I would donate it to a place that reconditions electronics in case they can use some of it. It was always a powerful and good sounding keyboard. It was originally designed to run with two Roland Cube amps. If anyone has any more information I would appreciate it, before I send up a coat hanger to see if there is and old battery stuck down inside. Thanks.

Kane Taylor's review"To complement my tech sheet entry"

Yamaha ps 55
Pardon my typos. Please see my tech sheet entry. 1973 sounds right. This is a very powerful keyboard, designed to run on two Roland Cube amps.YOU MUST NOT Y THE TWO CHANNELS TOGETHER. It is true stereo and instruments are weighted according to onstage placement of symphonic orchestra. I left mine at someone else's house too long and can't find the Yamaha power supply. I used to run on six D cell batteries but now I can't get all six in, so there may be an old one stuck down inside, don't know yet. If it will run I will be very happy even though I have a newer keyboard. This thing kicks butt onstage and the sampling is largely very nice. As usual, some horn sounds are a bit lacking in quality, but Yamaha was a leader in sampling in that era. Hang on to your original power supply and don't Y the two channels together. Run them separately into your sound board channels or use two amps. You can adjust the dispersion with the knobs left and right. If you can get a new one with the power supply, it's a good bet for the money. Saving arrangements may not be it's forte but it works really well for live performance.

Yamaha ps 55
4 octave keyboard 49 keys "arranger" public early 80s (1983 I think)
Member of the PS 35 series / 55, successor of PS 20 and 30

We find a headphone output on the front.
2 RCA inputs on the back, which allows input according to a turntable cassette player manual. Today we can enter a computer, mp3 player or an iPad to play in the street or in the mountains (lol) ...
2 RCA L / R outputs
A pedal input jack
1 input for power yamaha
Cover for 6 x 1.5 volt R20
2 speakers 12 cm 5watts power

1 3 mini sequencer tracks (Bass & chord / band / solo)
Bass & Chord section 1 (in normal mode, the entire keyboard is the orchestral sounds and / or solo)
1 arpeggiator section two and one change his lofi kind game console
Rhythm Section 1 (5 + 2x8 rhythms fill in)
Orchestra section 1 (2 times 8 polyphonic instruments)
1 solo section (2 times 8 monophonic instruments)
1 small effect section consists of a chorus, tremolo and "celeste" effect
Adjustable sustain for orchestras and solo sounds.
No velocity ...
Impossible to know if the generator is its analog or digital ... the machine was released in 1983 along with the dx7, but not obviously uses fm ... It sounds like these are analog predecessors, but impossible to have confirmation internetes the research is conflicting about and not based on any official documents ...


The config is very simple.
there is no editing will be possible for sounds ...


I had his cousin PS30 few weeks when I was 6 years old ...
Good in terms of archi arranger is exceeded, the interest of such a machine, if it is found in only a mouthful of epain is to divert its initial use is to make sound groundwater Vintage or to laugh with the bar that sounds to be kitsche (kitsche but not narrow ...)
It may also be one or two lead sounds ... just about a few dollars in a garage it will, but it seems PS even less grainy than the PS30 (impression?)
Can serve machine string of poor and lets go laugh on the beach (if you can find a battery ..)
In a ampilant his band and his solo, you can do some interesting things too (use effects)
it has a strong enough output level so it is well worth more entries listed ranges for certain uses ... but it has a little breath (MT32 kind)
For 150 euros, of course he will have a better track real synth: juno 1 or poly 800, another planet ... but this little ps is not ridiculous ... for a price "flea market / garage sale" there is no much to risk ...
Just for the box ultra pace kitsche we can find a interest ...
