You start by downloading the schematic here:

Scroll down to the link "Get Manual" and download the schematic. Note that it has several pages of parts list preceeding the schematic.
Next, put a 150 Watt incandescent bulb in series with the power cord to act as a current limiting fuse. Now replace the fuse and proceed with testing. You may find that one or more filter caps have shorted. Also pay particular attention the the BIAS power supply. You should see about -35 to -40 volts. Note that the series lamp will come on if excess current is being drawn and voltages will be low if the lamp lights. If the BIAS supply has failed, it is possible your power tubes have been damaged.
Increasing staticky noise when turning
If it is just while turning the control, open the unit and squirt some CRC226 into the control through the slot where the leads go in. You can bend the plastic spout to get it to spray into the slot. While your at it, do the other controls as well. CRC 226 is available at Home Depot in the electrical dept. Blue can about $2.70. Use only the 226 product as there are others there.

* ALWAYS UNPLUG YOUR AMPLIFIER BEFORE REMOVING TUBES *
If you can see that a tube is definitely not lighting up then it may be blown. If this amp has seen regular use then it may be time for a new set of tubes. Try replacing the 12AX7s first before committing to a new set of 6L6s. Though, if you have the cash available, a new set of power tubes isn't a bad idea either. I would advise you to do the preamp tubes first and play through the amp for a few days first before changing the power tubes.
Keep in mind... if a tube (or tubes) has blown, there could be another issue in the circuit. Swapping in a new tubes is a quick way to determine that. Then it would be time to take it to your local repair shop.
Good luck and keep rockin'!
My peavey valveking vk 112 is making a whistling
A high frequency feedback can be very hard to isolate without test equipment... you MIGHT have a "microphonic" tube that picks up from the speaker and feeds back... Tap the small tubes with a pencil and see if any of them "ring"... gentle taps of course... If one seems sensitive, swap like numbered ones around to see if you can find a happy place for them. Electrically there could be a bad ground inside causing these.
I notice you have 4 tubes in the output... REMEMBER when you used matched pairs... the members of the pairs do NOT go side by side all the way down the string...
Put each tube of a matched pair at the ends of the string of four, and the other pair as the middle two...

Almost ALL new electronic equipment use the same style cord now... You can find them at computer parts stores... but here is a HINT: You can usually find them at Thrift stores!
Peavey 14 bt mixer won't pan. Keeps sending signal to both outputs
If your Peavey 14 BT mixer is not allowing you to pan the audio signal and is sending the same signal to both outputs, there could be a few potential reasons for this issue. Here are some troubleshooting steps you can take to address the problem:
1. **Check the Pan Controls:** Make sure you're using the correct pan controls for the channels you're trying to pan. The pan controls are typically knobs labeled "Pan" or "Balance" on each channel strip. Ensure that they're set to the desired positions.
2. **Reset Pan Controls:** If you've already adjusted the pan controls and they're not working as expected, try resetting them to their center positions. This can help eliminate any accidental settings that might be causing the issue.
3. **Channel Routing:** Some mixers have routing options that can affect panning. Check if there are any routing switches or buttons that might be affecting the signal routing for each channel.
4. **Mono/Stereo Mode:** Some mixers have a mono/stereo mode switch that can affect panning. Make sure the mixer is in the appropriate mode for your setup.
5. **Master Pan Control:** Ensure that the master stereo output pan control is set to the center position. If it's panned to one side, it can affect the overall stereo output.
6. **Test Different Channels:** Try panning different channels to see if the issue is specific to one channel or affecting multiple channels.
7. **Firmware/Software Update:** If your mixer has digital components or software control, check if there are any firmware updates available. Sometimes, software updates can address functionality issues.
8. **Physical Damage or Wear:** Inspect the pan controls and associated circuitry for any physical damage or wear that could be causing the issue.
9. **Factory Reset:** If none of the above steps resolve the issue, you might consider performing a factory reset on the mixer. Be sure to back up any important settings before doing this.
10. **Professional Service:** If the problem persists after trying these steps, it might be a more complex internal issue that requires professional servicing. Contact Peavey's customer support or a qualified audio technician for further assistance.
Remember that the exact steps and controls can vary depending on the model of your Peavey mixer. Refer to the user manual for your specific model for more detailed information on troubleshooting and operation.
