Repairing the input jack on your Bugera 6262 amp head is a task that requires careful attention and technical expertise. If you're comfortable with electronics and have experience working with amplifiers, you can follow these general steps to access and repair the input jack. However, please note that working on high-voltage electronics can be dangerous, and if you're not confident in your abilities, it's best to seek professional assistance.
Safety Precautions:
Disconnect the Power: Ensure that the amplifier is completely unplugged from the power source before you begin any work. This is crucial to prevent electric shock.
Gather Tools:
You'll need a set of screwdrivers (Phillips and flat-head) appropriate for the screws used in the amplifier's casing.
A soldering iron and soldering supplies (solder, desoldering braid, etc.) for working on the input jack connections.
Opening the Amp:
Remove the screws holding the amplifier's chassis in the enclosure. These screws are usually located on the rear panel or sometimes underneath the amp. Keep track of the screws and their locations.
Accessing the Input Jack:
Once the chassis is removed from the enclosure, you should have access to the internal components of the amplifier. Look for the input jack and its connections on the PCB (printed circuit board).
Repairing the Input Jack:
Carefully examine the input jack's connections. If you see any loose or broken solder joints, you'll need to re-solder them. Use a soldering iron to heat the solder joint and apply a small amount of new solder if necessary.
Testing and Reassembly:
After repairing the input jack connections, it's a good idea to test the amp's functionality before fully reassembling it. Plug in your instrument and ensure that the input jack is working as expected.
Reassembling the Amp:
Once you've confirmed that the input jack is functioning properly, carefully reassemble the amplifier. Make sure to secure all screws and components properly.
And why would equipment blow a fuse the minute you turn it on? Well, I would say because it's defective. Bad power supplies, burnt components, shorted diodes and/or transistors or dead IC's. It's repair shop time bud and make sure that shorted speaker wires or defective speakers didn't damage it, as reconnecting a freshly repaired unit to the same wires/speakers could damage the unit twice.

if its not right next to where the AC power plugs in, or part of the power plug itself ( lil notch in cable recepticle that will allow it to slide out ) then it would have to be inside the mixer on the power pcb. ( the board the power cable connector is soldered to)
If there is one, it's usually right where the ac power plugs in or right next to it (might need flathead screwdriver). If not you have to take the back panel off and it could be either in fuse clips/holder or sometimes even soldered into the PC board.
Open unit. 1. Look for cables knocked off. 2. Using bright light look for circuit board cracks and broken solder. 3. Look for broken pots, especially the main slider. All of these problems are repairable by competent electronics tech.
This is a bi-amped speaker. That means it has a separate power amplifier driving the bass woofer and treble horn. They have a low-level electronic crossover to separate the frequencies to the appropriate speaker. The electronic crossover is the least likely to fail... so you need to do a test:
You will need to open the unit and using an ohmmeter check if the woofer speaker voice coil is open or has continuity...It should be around 6 to 16 ohms. If it is above that, the speaker itself is blown and will have to be replaced. If the speaker has continuity, then the bass amp has failed and will require repairing by person that is adept at electronic repair. Before opening the unit you MIGHT be able to diagnose whether the speaker itself is blown by seeing if the woofer generates a thump when power is turned on or off. If it does, then likely the speaker is OK and the problem is the amp, otherwise the tests above need to be done. Usually these plastic cabinets are held together with seveal scrwes from the back. Some are in :deep "wells" and will require a very long shaft phillips screwdriver... and they often are long screws that wear one out unscrewing them. A genlte pry after removing the screws will separate the back and the front.
This could be caused by a faulty cable or a fault on one of the ends of the cable. Open each side of the cable, the jack should screw off. Once it is open check to make sure that both of the wires are connected firmly. If they're not, you will need to solder them on properly and if they are, then this is not the problem.
This could be a due to the settings on your speaker or the mixer you are using. On the speaker, check that the low's mid's and high's are set correctly and then check the mixer to see if the line in from the guitar is set correctly and check that the line out is set correctly. If all of this is fine then it could be due to your guitar DI.
Check that your DI is set correctly,e.g. Make sure that the DI is not set to run a link between both lines, it should be set as single.
