on't even think about replacing a ceramic with magnetic cartridge in an old record player unless you are a qualified electronics repair technician. We will not assist non technical persons in this matter.
Troubleshooting for all preamps:
Are you getting a 60hz hum when the phono preamp is hooked into your receiver/computer?
- Make sure it is NOT hooked into a 'PHONO' input it is designed to hook into 'TAPE CD AUX' etc inputs!
- Make sure your house outlet is grounded properly with a little 3 PRONG plugin tester from radio shack or a hardware store.
- Make sure you are connecting the third grounding wire coming out of the turntable to the external METAL framework of your receiver or computer.
- If you get a loud hum when hookin up only the preamp to your receiver/computer, this does not indicate a fault in the RCA preamp. Many electronic circuits require something called 'termination' When the inputs of an amp or preamp are 'floating' then the output will reflect this.
This RCA to 3.5mm plug is what you will need for your computer hookup.
And here it is in action!
We also have a regular 'RCA' to 'RCA' patch cord to connect the output of the pre-amp to your stereo. If you don't have any additional 'RCA' type stereo patch cords sitting around you may wish to have us send one along with your new preamp. Just $2 will save you some lookin or a trip to the store.
