JVC L T11 turntable spins to fast jerry, rigged adapter
I purchased an L T11 table. The power adapter is not the original. Info on adapter is input 120v 60hz 18watt. output is 12vdc 400ma max plug tip is +. class 2. On the back of the table it reads DC 12-14volt. Yhe problem is the table spins way to fast. I tried adjusting the speed with the 33&45 adjustment screws and still can't slow it down enough. Is it possible the adapter is to powerfull causing the table to turn to fast

Probably as long it produces DC. However you will have to adjust the speed. As the unit was set for a certain voltage which wouldn't change. It will either go fast or slow depending on what the original voltage was. The speed adjuster will either be two presets one for each speed that could be located under the turntable base (covered by a sticker) or on the power board of the deck. Or they might be on the motor itself.
several people are having this trouble but most seem to work ok .. the unit has its own built in preamp and digital interface so, in this case, you dont have to worry about what cartridge it has .. in fact you can hook its rca outputs to the aux of an amplifier (not the phono input) .. or you can connect them to your amplified computer speakers thru an RCA sterio to 1/8 inch jack adapter ... i am working on a solution remotely since i dont have the unit yet ... but here is a suggestion (for xp) .. find the volume icon in the bottom right task bar .. double click on that .. that should bring up a box with several volume controls .. make sure none have "mute" checkmarked .. turn up all the controls so you cant miss anything if it comes thru ..try the table ... now click on "options" in that volume control box then "properties" then put a dot for "recording" .. select all of the volume controls in the bottom box .. now click ok .. that will give you some level controls for recording . turn them up ..then select them one at a time to see if any work (with table playing) .. if none of that works then there is likely an incompatability .. you might look for upgraded drivers for your audio card .. .. i will likely have more on this as i remotely get one working or if i can find one to play with .. maybe a few days .. some audio cards turn off sound outputs when you are in the record mode .. thats so you dont get screeching thru the mic input .. but there is usually a way to defeat that .. the units software should have done that for you .. i have found some popular laptops that horrably dont have sterio inputs (only monoral for the mic input) ... on a few that can be fixed with special software but on others (like my inspiron 6000) there is no hope ... i purchased an audio input adapter that connects to the USB port .. that gives you several analog inputs that are sterio .. your turn table's digital output doesnt need analog inputs so you are ok unless you want to use the RCA jacks as audio input ..
