Re: wiring

It's really not hard if you know how solder, my suggestion is to place it upside down on a desk with the tow arm hanging off the desk so not to damage it, then take the 4 feet off by simply twisting them off then remove all the screws, now that all that is removed you'll notice that where the rca's go in they are pinched in a piece of plastic simple remove the screws and it'll un snap take the remaining plate off and your in ready to solder

Re: wiring

It's not as easy as it looks or sounds. If you have to come on this site and ask this question, then I DO NOT suggest you attempt this repair. You will have to have some decent soldering skills, as well as mechanical capabilities - it's kind of difficult to get to the PCB where the RCA are soldered on to. If you damage the PCB, it is not replaceable, as that part has been discontinued by the manufacturer. So, with that warning... it's not that hard, if you are mechanically inclined, and all you have to do is get to the RCA's PCB section, and remove the base and locking mechanism. Then solder off the old RCA's, solder on the new RCA's, put it back together, and your done. Hope this helps.

Onkyo TX 8020 Receiver sounds muffled. I have the Onkyo TX 80202 receiver and just bought the Audio Technica AT-LP120 turntable to connect to it. I have the turntable switch to "Phono" (so as to make use...

This sounds like a wiring problem. Perhaps a faulty earth connection inside the lead or the plugs to and from the turntable. Also check the connections to the cartridge, they can become loose or be connected wrong. Say a channel to the earth connection.

Poor sound quality from a technics SL-D210

Generally either a faulty connection to a lead or cartridge. Or a faulty Cartridge. If you switch the left and right channels of the phono leads the missing sound should move to the left and the right come to life. If it does not then there's a fault in the magnetic cartridge pre-amp in your amp.

Very low sound after new needle installed

Firstly the cartridge could be faulty or incorectly wired. I think what you are refering to is a magnetic cartridge pre-amp. If the turnatable has seperate audio connectors these should be plugged into the "phono" socket. And not an "aux" or "CD" input. If there is no phono socket, you wouldn't be able to plug a pre-amp in anyway. Yes the deck if it is built in should have this pre-amp built in. However these pre-amp can fail!
To test if the pre-amp is working, even if has no phono socket, unclip the leads to the cartridge. With your amp on, touch the end of each wire with your finger. On two you should hear a buzz - one for each channel. If it's not loud then there's a problem with the pre-amp. If you do get a decent buzz the cartridge is faulty.
You can also trace the wiring to the pre-amp inside the unit, if you wish to fix it. It will almost certainly end up at an IC, which should be replaced.

Gemini XL-BD10. Always worked fine. Started sounding muffled and "dirty." Thought it was the needle. Replaced it with a new one. Still the same. Tried a new set of RCA cables and ground wire. Same thing....

Check the internal circuit of the deck, follow the leads from the cartridge. Perhaps a faulty resistor or something else in any pre-amp. Make certain also it's not your amp that has not got a faulty phono pre-amp stage.

Hi,i got a problem with one of my technics 1210 mk2.Sound on the right monitor is ok,but there is not sound at all on the left monitor! I try to replace the stylus,but nothing....Please help?

Hi the only thing in between is the cartridge, wires and phono plugs at the back. There is a small circuit board (no electronics on it though) inside that the wires go to first. The possibility are , cartridge faulty (most likely i would guess), wire off the circuit board or the phono plugs/sockets at the back loose. Check the wires on the cartridge are ok as well. Have you also swopped the outputs just to check the cable to the mixer/amp?

Hope that helps
