Hartke Bass Amplifier Half Stack with Hartke 3500C and 410XL Questions & Answers
This problem has to do
Easiest way to check is to measure the resistance between the ground pin of your cord and the chasis of the unit. It should be very low. That is the only critical one... Look at a receptacle. See one bllade is wide? That is the neutral. The other one is the HOT side. The HOT SIDE should go to either the fuse or the switch first in your unit. If you have those right the third wire will be right.
When powering up an amp there often is a noise until the amplifiers balance out. Very high quality and high power amps have a relay that disconnects the speaker until balance is reached... but the smaller amps do noot have this feature.
Dropped Hartke amp b 600 and now it has no sound
There are too many possible problems for someone to advise you without the amp on the bench. I suggest taking it to an authorized Behringer repair as they will have better access to parts should it be a cracked board.

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.
