I have a lowrey m-375 organ. The lower keyboard works sometimes and other times it just doesn't make any noise at all. Very rarely the upper keyboard cuts out but never for long, any ideas? thanks

These older units like this usually inherit intermittent problems like this from sitting up and gathering dust. There are many switches and relays inside this model, and other electrical connections that would get dirty or corroded over the years. I think a good professional servicing would fix this.

SOURCE: i have a lowrey organ and when i plug it in it

If you feel comfortable doing it you could try removing the back and examining the power supply. Make sure the power cord is not plugged in. Remove the screws holding the back on the organ. Look to see where the power supply is. It will be a fair sized metal box that the power cord comes out of. Look for a fuse holder on the box.If there isn't one or you already checked the fuse look to see how the power supply is fastened down. If you can remove it you can check the power cord from the plug end to the connection in the power supply with a volt ohm meter on the lower resistance scale. Check both sides of the power cord . Look for an internal fuse soldered into the circuit if there is one. Check it also. You can also check the power switch the same way. Think of the power cord and switch etc as a garden hose. You want to make sure that the flow of electricity is not interrupted any where between the plug and the power transformer. Do all these tests with the cord unplugged. Also avoid touching anything connected to the filter capacitors as they store dangerous amounts of electricity. If none of this helps note the plug that connects the power supply to the organ. Unplug it and take the power supply in to be tested. A good piano service place should be able to direct you to someone. Also remember that something had to make the power supply fail if it is indeed faulty. None of this is simple or recommended for a person who has no experience with electricity or electronic repair. If you feel at all hesitant about doing it you are better advised to consult a repair person. If you do have experience but no schematic you can still usually find the problem with careful thought and procedure. Break the circuit down into modules and test them one at a time starting with the power supply. It could be something as simple as a frayed cord or blown fuse to something as complex as a burned out transistor or faulty tube ( in the case of older organs) causing the power supply to fail. I once repaired a home organ that the power supply blew in again because of the customers house wiring. That particular wall plug in had been wired improperly. Hope all this helps.

SOURCE: Our Genie Lowrey 44 organ does absolutely nothing

A little more info is needed here. Are there any lights on this unit at all? Are there some normally? If so, then yes check the main fuse. If not accessable externally, it should be located close to where the power cord enters the unit. Check it (when unplugged please!!!).

If that failes to resolve it, please let me know and I'll research the specific model in the meantime.

Thanks,
Dan

Here is a site to download manual:

http://www.lowreyforum.com/lowreymanuals.htm

A Leslie is special speaker system that is spun to break up the sound so it doesn't seem to come from a single point.

Sometimes the Leslie speaker is in a seperate cabinet fromthe organ, and SOMETIMES it is a simulated Leslie that is done with multiple speakers and electronic switching. If the Leslie is an external one, it usually attaches via a cable that often has either 9, 11, or 13 pins.

SOURCE: Lowrey organ C# and D# on both keyboards don't work. Fixable?

We can only guess what model you might have and whether it is tube or solid state.

If it is a vacuum tube type, probably one tube is burned out... likely either a 12AX7 or maybe a 12AT7 as a guess.

If it is solid state and the unit has not been moved to cause a loose connector, better to call a tech. If it has been moved, you could look for a loose connector.

Why does my lowrey organ not make a sound after I have switched it on?


This is a generic answer for this kind of question.
When there is no sound
Check the obvious.
Is there a light on the organ indicating it is on?
  • Plug it in to a known working wall socket, switch on at the wall
  • Switch on at the organ, check light
  • Very old keyboards need a voice to be selected!!
  • Turn master volume up
  • Turn any other volumes up
  • i.e. lower manual volume
  • upper manual volume
  • swell pedals down
Sometimes a sustain pedal plugged into a volume pedal socket will mute the output, check this.
Headphones out, most headphones will turn speakers off, sometimes the headphone switch can be dodgy, work the headphone plug in an out a few times
There maybe a switch that turns off the speakers, look near the output sockets
Software volumes up, check display, if any.
MIDI instruments, check local control is ON
Still no sound?
Can you hear anything from the speakers?
Hiss or hum usually means the speaker is ok
Total silence may indicate speaker failure, but only if there is one speaker, as in older home organs, or smaller keyboards
Try headphones next, TURN Down master volume first just in case!
If there is some sound, very quiet and gross distortion then possible power amplifier failure.
If your instrument has any kind of line out as well as a headphone jack, try these.
The line output will likely be a pair of phono sockets,like you have on HiFi equipment, 1/4 inch, 6.35mm jacks, like the bigger headphone connector, a 3.5mm socket like the smaller headphone connector, or even a DIN connector on older equipment.
Connect these to the aux (or Line or CD) input on your HiFi, guitar amp or similar. (some times these outputs will drive headphones, usually you will only hear anything in the left side). If this works then it is very likely the power amplifier.
Further tests on MIDI equipped keyboards would be to see if the MIDI does anything.
If MIDI out works and there is no sound, and MIDI in makes a sound this points to local being off, buried somewhere in the menu will be local on or off, make sure it is on.
If MIDI out doesn't work then the failure is likely to be internal power supply or something else critical (not nnecessarily major).
Power amplifier failures in newer, low power, keyboards are often the power amplifier chips (i.c,s), older amplifiers may have just blown their fuses but one or more output transistors may have failed.
Cost of repair will be down to the time it takes to get to the fault, taking these to bits and putting them back can take a lot longer than the repair.!
Hope this helps, Chris the Fader

Have an older Lowrey organ with loud hum.


Of course it is repairable.

Find a competent repair person. You did not describe the "noise". If it is 60 cycle hum, the filter caps need replacing. If it is an organ tone, then probably a key contact is stuck.

Lowrey catillion organ with loud static noise


Try posting on the organforum.com.

It sounds like the power amp has a problem. Probably filter capacitors have gone bad.

Need a fuse for a lowrey-genie organ-44


If the fuse blew, it is for a reason. Probably shorted filter capacitors.
