Question about Shure Beta 58A Professional Microphone

Value of capacitor in Beta 58 headshell assy required to correct crackling

I have identified and removed a noisy surface mount capacitor on the cartridge interface pcb in the headshell assy. Even though the mic now appears to work perfectly without it, I would like to replace it but need to know the value. I have been quoted $319 to replace the cartridge assy and as the cap is worth about 20 cents, my options are clear. One leg of it goes to the yellow cartridge wire and the other leg goes to a SM electro.
Im not after the whole schematic so I can start a microphone factory, I just like to recycle and save money. Thanks Jack Jensen

    Thanks for responding. The Shure wireless Beta 58 is a PGx2. It has tested fine without the noisy capacitor and gone back into service, but it would still be nice to have a schematic if one is available. Thanks Jack

Samsung R88, has no picture but the sound is working. I have checked the capsitors and they are fine any other ideas?


Check for voltage to the inverters. If there is no voltage to the inverter section, check for a surface mounted fuse and check it's condition if present.
Replace the larger value caps in the power supply as some may not show physical evidence of failure. Also remove the power supply board and check the surface mounted devices underneath to make sure there is no sign of a cold solder joint- the same on the inverter section. Good solder connections will look like a tiny volcano on the circuit board with the wire lead protruding from it- with no gaps, or areas that might suggest solder did not fully flow. Reflow solder to those connections if found. The Surface Mounted devices themselves should have smooth transitions in the solder, if not, reflow those with a soldering iron as well.


If there is voltage there, start by replacing the electrolytic capacitors in the inverter section. These will be values like 1, 2.2, 4.7 microfarad at 25 or 50 volts, These are part of the step up oscillator portion of the inverter. If that does not remedy it, check the transistors- a B&K type tester will not always give an accurate reading because the inducatnace is too low in the inverter transformer in circuit with it, so those usually need removal for accurate testing. Sometimes only one transistor needs to be removed.

If those test out okay, or are surface mounted or 4 leads plus tab versions first replace the larger value electrolytic capacitors, those will have values of 220, 330, 470, 560, 1000 microfards(sometimes higher capacities) at 25 or 35 volts. These can fail without visual indications. as they will be easier to remove than the surface mounted devices and likely cheaper too.

I need the torque specs for replacing the valve cover gasket on a 2001 chevy cavallier 2.2 liter 4cly. thanks


This should do the trick, torque to specs then additional 90 degrees turn on all bolts

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.


  • Use the following sequence in order to tighten the cylinder head bolts: Tighten
    1. Tighten bolt 1 to 63 N·m (46 lb ft).
    2. Tighten bolt 2 to 58 N·m (43 lb ft).
    3. Tighten bolt 3 to 58 N·m (43 lb ft).
    4. Tighten bolt 4 to 63 N·m (46 lb ft).
    5. Tighten bolt 5 to 63 N·m (46 lb ft).
    6. Tighten bolt 6 to 58 N·m (43 lb ft).
    7. Tighten bolt 7 to 58 N·m (43 lb ft).
    8. Tighten bolt 8 to 63 N·m (46 lb ft).
    9. Tighten bolt 9 to 63 N·m (46 lb ft).
    10. Tighten bolt 10 (stud bolt) to 58 N·m (43 lb ft).
    11. Then tighten all bolts an additional 90 degrees

    Crackling sound from speakers, intermittent, but seems to start after warming up


    If these speakers are internal to the TV, chances are an internal component is getting noisy -- probably a capacitor -- and will eventually need replacement. That's not something you can do yourself. It's also possible there's a loose connection or a noisy volume control, but that's less likely, and again, would require a qualified serviceman.

    If the speakers are external - that is, you've plugged them into the set -- check the connections at the set and at the speaker to make sure they're not corroded and are firmly seated. Sometimes just unplugging and replugging them a couple of times rubs off enough corrosion to solve the problem. Also wiggle the wires close to the connectors on the cables. If that causes the crackle, replace the cables.

    Componenet failure Acer aspire 5920 I do not know if its a diode or capacitor. Anyway when I go to power on I get nothing. My power adapter light goes dim. Does anybody have any idea on how to identify the...


    start up circuit problem, double check the output voltage on the adapter should be between 16vdc -20vdc, if ok connect a load to it example dc bulb/led or the battery of the laptop, if it remains on the adapter is ok, next check the laptop battery, remove it from the laptop and using a meter check the voltage and polarity.monitor the voltage to see if it is falling or holding,it should be holding, if all is well the next step is to check the voltage at the switch, this requires you to take apart the laptop to trace/test the voltage form the input to the battery to the mainboard to the switch and back to the mainboard. if the voltage is not present on the main board you will have to check the components to see which one is defective,if a protection diode it will be a very small component (smd) usually black in color and located close to the input connector.you will have to replace it,which will require some special tools and a lot of steady nerves.if a capacitor it will be brownish in color (smd)Surface Mounted Device.
    Hope this helps

    Benimur, you are correct, except that the Beta 58 is a condenser mic that required phantom power. In that case all 3 lines are used. Included below are the connections.
