Baldwin pianovelle ps2500 my piano turns on but speakers don't sound can someone give a hint to solve this problem
So I got a used one of these for free because it had the same issue.
I read about battery failure, so I opened up the piano and sure enough the battery had corroded. I also read that the battery is only necessary for the memory feature, which I don’t care too much about. I pulled out the board (super easy to do, no screws or anything, it just pops out) and took it a local electronics/tv repair guy. In about a half hour he took off the battery, fixed a bad trace on the board with a quick solder, and handed it back. $40.
Plugged it back in, bam works like a charm.
As long as there wasn’t too much damage from corrosion, a repair guy should easily be able to do what I described.
I hope this solves your (and anyone else’s) problem!

How do you do a factory reset on a casio wk1630?
I finally figured it out! 2020!! Turn off the keyboard. Hold the enter button, and press power. Press YES to reset! That will completely reset it as if it were new!

I need to know the value of the Resistor "R1" in
Let us use a bit of logic to resolve this... I have an Axiom but it would be a lot of screws to take out to get to the part... so let us think about this. The resistor value starts with a "1" and we know it is 5% tolerance (gold). we know the resistor burnt up with likely 5 volts on it... Value could be 1000 ohms, however the voltages present (12 volts max) would NOT have burned up a resistor of 1000 ohms. The USB area is mostly 5 volts and across 100 ohms is only a quarter watt... not enough to really burn up a resistor... First thing is to MEASURE that the resistor s open... in spite of being burned, it MAY still be OK... these resistors now usually either open or remain close to their value. The resistor ALSO may be a fusible resistor intended to act as a fuse... Is the resistor open or not? is it near a resistance with a "1" as the first digit? If it is not open I suspect it is not all of the problem. In that case, look for a burned circuit trace on the board. If it is open, then MEASURE the voltage across the resistor with the power applied. If you find 5 volts, then it MIGHT be a 10 ohm used to limit the USB current to 500ma. Get back to me with your findings... I have unraveled many of these things...

Need reverb tank for a Marshall Amp 8280,but don't know what type
Try this website:http://tubesandmore.com/ Look under reverb tanks. Check to see how many springs your old tank has and what size it is. I think Marshall used Accutronic tanks but have a look at all of them. There are pictures and info for each. Hope this helps.

MY ORGAN HAS NO SOUND
Can you please Edit or add a comment to your question, what make and model of organ is it? Have you tried it in a different AC outlet? Do any lights come on when you switch it on? Have you tried the headphone output as well as the speakers? Does it have a line output? What happens when you move the volume knob and or the swell pedal, do you hear any noise?

After about 30 minutes of
Have you checked that it is not the amp that is the problem? This is a fairly common thing to have the amp heat up and the thermal protection shut it down partly. Since the bass drops, a loose connection or bad guitar cable can cause that. If the signal becomes capacitively coupled only the treble will come through and be very distorted. Try a new cable. For the guitar, open the electronics area and look for loose or broken wire.
