If the volume knob on your model #bc345crs is not functioning properly, there could be a few potential causes. Here are a few troubleshooting steps you can try:
Check for any debris or blockage around the knob that might be preventing it from turning properly. Clean the area with a soft cloth to remove any dust or dirt.
Try turning the knob in both directions to see if there is any difference in the sound output. If the knob only seems to work in one direction, it could be a sign of a faulty potentiometer, which is the component responsible for regulating the volume.
If cleaning the knob and turning it in both directions doesn't improve the issue, you may need to open up the device and check for any loose connections or damaged components. This should only be attempted by someone with experience working with electronics.
If you are unable to diagnose and fix the issue yourself, it may be best to bring the device to a professional for repair or replacement.
It's possible that the CD is not compatible with the BR180, or there could be an issue with the CD itself. Here are a few things you could try:
Check the format: Make sure the CD is in a format that the BR180 supports, such as MP3 or WAV.
Clean the CD: If the CD is dirty or scratched, it may not play properly. Clean it carefully with a soft cloth or a CD cleaning kit.
Use a different CD: Try using a different CD to see if the issue is with the CD or the player.
Check for firmware updates: Make sure the firmware for the BR180 is up to date. If not, update it to the latest version.
If none of these steps work, it's possible that there may be an issue with the BR180 itself. You may want to contact the manufacturer for further assistance or bring it to a qualified technician for repair.
In a transformer, maximum power refers to the highest amount of power that can be transferred from the primary winding to the secondary winding without causing damage to the transformer. The maximum power rating is determined by the physical characteristics and the insulation properties of the transformer.
The maximum power rating is usually specified by the manufacturer and can be used to determine the maximum load that the transformer can handle. If the load exceeds the maximum power rating of the transformer, it can overheat, and the insulation may break down, causing damage to the transformer.
The maximum power rating is determined by the size of the transformer and the amount of current that can be safely carried by the winding. The number of turns in the winding, the thickness of the wire, and the insulation materials used all affect the maximum power rating.
It is important to choose a transformer with a maximum power rating that is suitable for the intended application. Using a transformer with a lower power rating than required can result in poor performance or damage to the transformer while using a transformer with a higher power rating than required may be unnecessary and can increase the cost of the system.
In summary, the maximum power rating is an important specification to consider when selecting a transformer for a specific application. It indicates the maximum amount of power that the transformer can handle without being damaged, and selecting a transformer with an appropriate maximum power rating can help ensure safe and reliable operation.
There is a super capacitor that works as a battery for memory backup. The spec for this super capacitor is: 0.22F X 5.5V. This part is easily accessible once you remove the sheet metal over of the receiver. The following image is Sony STR-D915 with case removed.
Most current receivers no longer include a PHONO input. Perhaps what could be done is to purchase a phono to line level pre-amplifier to go along in your purchase for a new receiver.
Will scout around for receivers and post back additional information.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Wiring a Delta M3 microphone to a Cobra 29 LTD Classic CB radio requires connecting the wires from the microphone to the corresponding pins on the radio's microphone jack. Here are the steps:
Locate the microphone jack on the front of the Cobra 29 LTD Classic CB radio.
Examine the Delta M3 microphone's wiring. It should have four wires: a black wire, a red wire, a white wire, and a shield wire.
Determine the pin configuration of the microphone jack on the Cobra 29 LTD Classic CB radio. The pin configuration is usually printed next to the microphone jack or in the owner's manual.
Connect the Delta M3's black wire to the pin on the microphone jack that corresponds to the radio's ground connection.
Connect the Delta M3's red wire to the pin on the microphone jack that corresponds to the radio's positive voltage connection.
Connect the Delta M3's white wire to the pin on the microphone jack that corresponds to the radio's audio input connection.
Connect the Delta M3's shield wire to the pin on the microphone jack that corresponds to the radio's shield connection.
Test the microphone by speaking into it while monitoring the audio output on the Cobra 29 LTD Classic CB radio.
Note: If you are unsure about the wiring or pin configuration, consult the owner's manual for your CB radio or seek assistance from a qualified technician. Improper wiring can damage your radio or microphone, and may result in poor audio quality or no audio at all.
Perform a quick test on the wires to check that they work. Check outlets, power cable, and fuse. Most subwoofers have a "standby" LED that glows to indicate active power. If it's not lit, check that the subwoofer is securely plugged into a wall socket, surge protector, or power strip.
