Johnson Ma100 Lynchburg Mandolin Questions & Answers
Just bought a garman 14 ft. jon boat wide
Check fuel filter first to see if there is any trash or water clogging it up. Make sure the gas tank is venting and the fuel connections are secure. Check both cylinders for spark, the gap should be around .030". If motor cranks up and tries to die again pump the primer bubble to see if this helps, if it helps this would indicate a fuel pump problem, if not then the first thing I would do is clean the carburater which is more than likely what is wrong.
The body has sunk on my mandolin between the sound
Sounds like the bridge was either in the wrong place or the string tension excessive.
Sometimes there are low, medium, and high tension grades of strings.
Find out what your mandolin requires.
If the strings are snapping, you are tuning them wrong. They should NOT break with 10% over the final tuning. It sounds like you may be using the wrong strings.
De-string it to see if the wood will recover. If it doesn't take the instrument to a Luthier for repair.
Sound post has fallen inside F style Johnson mandolin.
You may be able to help this prob. your self. You will need a set of hemostats about 10 in. long. A nickel sized dental mirror a flexible LED light . First of all unstring it , put strings a side.Next look in side to the under side of the top of your Mandolin .With your lite and mirror you should see a spot where the post was org. placed.Now with your hemostats reinstall the post. Now this is like building a ship in a bottle, but it can be done , but just a little at at time. You need to lift up the whole top. Remember the top did not drope down all at once, nor will you rase it up all at one time. A little eack day untill you have reached a perpendicular point . One more thing, you post fell because the insturmant was to dry.You need to keep it humidfided . Take it to the shower with you. dont get it wet let it soak up the steam, it will help you get the post back up right and it will love you four it. Get a humidfier for it OK
Guitar strings on a mandolin.
Looking at your desired notes the mandolin is standard tuned to gdae.
So three of the four notes are already available, just put the "d" mando strings where the "g" ones would go and the "g" ones where the "D" ones would go the highest is already a "e" and I am sure the "a" would tune up to a "B" with little risk.
You can also look at string sets made for the madochello or possbly octave mandolin.
Good luck,
The dude.

The most likely case is that one of the main output transistors (if which there are many) is shorted. When the protect circuit senses DC on the final output, it will not allow the output relay to come on to protect the speakers from raw DC. With the power removed, you can check between each outputs Emitter and Collector and you will probably find close to zero ohms. From that point you need to unsolder each of the pins of the bad channel until you find the shorted device(s) and replace them.

No or very little sound from Fender passport
Depending on the model, there are four around that date, it could be the insert jacks are tarnished reducing the signal flow between the pre amp stage and digital power amplifier. It could be the power amplifier has failed. It could even be customer error in wiring.
This assumes there is the correct level of signal entering the input sockets of course.

Breaking Roland RD 600 hammers
The Roland RD-600 is a digital piano, and its hammer action mechanism is designed to simulate the feel of an acoustic piano. The hammers in digital pianos like the RD-600 are typically made of materials like plastic or a combination of materials to replicate the weighted feel of acoustic piano keys.
The breaking of hammers in a digital piano is not a common issue, and it's not typically related to the age of the instrument alone. Several factors could contribute to the breakage of hammers, and it's essential to consider the following possibilities:
- Excessive Force: If the keys are played with excessive force or if there's any physical damage to the instrument, it could lead to the breakage of hammers.
- Material Quality: The quality of materials used in the construction of the hammers can impact their durability. If the hammers are made from subpar materials, they may be more prone to breaking.
- Manufacturing Defects: In some cases, there could be manufacturing defects that make the hammers more susceptible to breakage.
- Maintenance: Lack of proper maintenance, such as cleaning and regular inspection, may contribute to the wear and tear of components, including hammers.
If you've observed a pattern of hammers breaking with regularity, it might be worth investigating the specific cause. If it's due to excessive force or physical damage, adjusting playing habits and taking care during transport can help mitigate the issue.
As for whether it's worth purchasing new hammers from Roland, it depends on the extent of the damage and the overall condition of the instrument. If the RD-600 is in good condition otherwise and you enjoy playing it, replacing the hammers could be a reasonable option. However, you may want to assess the cost of replacement hammers compared to the overall value of the instrument, factoring in the cost of a used RD-600 and any potential future maintenance needs.
