2. What is Thermal Grease and why is that important? Thermal Grease is a heat transfer compound used to dissipate heat from high current components to a heat sink. Because most transistors get very hot they require a heat sink. When the a device is completely flat to the heat sink, the heat is drawn away from the device. Most transistors have slight imperfections and are not perfectly flat. The thermal grease helps fill in those pores so the heat can escape more effectively.

3. What is a Basic Setup? Plug in a music source into the input of your amp, turn up the volume, not maxed, turn all the tone controls to the middle, including the PAN control, check all of the Mute and routing buttons, plug in your speaker and or headphones and power the amp ON. You should hear the instrument. If you don't, then something is wrong. Check your cables first (the cable going to the input of the amp and the one going to the speaker). Check your speaker too. It is best to check those things with a separate amp. In our experience 25% of all of the amps returned were due to the setup of the amp. Added: 9-11-2008    Revised: 11-10-2008    back to top
4. Does Carvin sell CARVIN logos and Badges? No. Carvin does not sell badges, logos, or labels. We started to see gear on eBay being sold as actual Carvin-made equipment. The logo made it look like "real" Carvin gear. Unfortunately, the quality of many of these wasn't up to Carvins standards, so we stopped offering the logo.

6. How should I box my amp to send it in for repair? The amp should be boxed up in its original packaging. If that is not possible, then box it up as best you can. Make sure to leave a protective cushion between the amp and the box. During shipping the amp will be exposed to rough handling. If improperly boxed, the unit will be damaged. Carvin is not responsible for shipping damage due to improper boxing. Remember to fill out your RMA form. Added: 10-21-2008    Revised: 11-10-2008    Generic FAQ    back to top

10. Can a Carvin Tech Modify my amps if I send them in? No. Carvin Technicians are not permitted to MOD (modify) any amplifier. It is against company policy.

11. What is Moisture and Corrosion, and why is that bad? Moisture is the presence of water in trace amounts. It can cause rot in wood and corrosion in metals, both of which are the main materials in your amplifier and cabinet. When moisture goes inside the amp it can corrode the input and output jacks (causing intermittent crackling, popping, and volume loss), damage the cables inside the amp, and short traces on the circuit boards. If corrosion is present on any of the jacks, the best thing to do is to replace them. For light corrosion, applying contact cleaner to the jacks will help.

12. What do I do if I get Dust or Sand inside my gear? Dust and/or sand should never go inside the amp. If any debris goes inside try to clean it out as best you can. Dust and sand can block the fan and vents, causing the amp to overheat, and they can also short components inside. Any debris inside the chassis will also absorb moisture and cause corrosion to form on chassis and circuitry. Added: 9-11-2008    Revised: 11-10-2008    Generic FAQ    back to top
13. What do I do if my amp gets struck by Lightning? Lightning can cause extreme and intermittent failures to all electrical equipment. Most of these issues are very difficult to repair and usually return after time. In the case of a direct hit, the amp will likely not work well ever again. If there was a black out for a few seconds and the amp does not power back ON, check the fuse. For a replacement fuse click on "Fuse and Bias Values" in the FAQ Categories menu.

14. When I tap the top of my amp the signal goes in and out, what do I do? This is a characteristic of something inside the amp being loose. In most cases it is a loose connector, but it can also be dirty or corroded contacts, a bad ribbon cable, or broken solder joints. To check this, take the amp out of the enclosure and verify that all harnesses and connectors are installed correctly. Disconnect and reconnect the ribbon cables. Power on your amp and verify that it is working properly. If the problem persists, you may have to replace a connector and do further troubleshooting. A cable can work its way out from the vibration of a speaker. For a replacement cable click on "Parts". Added: 9-11-2008    Revised: 11-10-2008    Generic FAQ    back to top
