Conrad Johnson GAT Owner Problems?
Just wondered If any fellow GAT owners have had problems with their units and had to send back to C-J for service?
I have a 4 week old unit that the volume has become lower or completely drops out on right channel on all inputs. I replaced tubes but nothing changed, any Ideas what could be wrong? Hooked up my Pass XP-20 and works like a champ! Thanks In Advance |

Is the level dropping also shown on the display? .. I'm presuming the audio level readout remains 20/20 or whatever it's set to.
I've not had any issues with mine other than the very rare failure of the "Standby" LED to illuminate when entering Standby. I replaced the "logic" board, and the issue continues. It's an extremely minor issue and doesn't affect normal operation at all. If you're a "techy" type person there are a couple things you could have a look at by popping the top... if you have to think about it, it's not a good idea. Sounds like you've tried all the normal checks..so the following may be useless: be sure the GAT RCA-Out connectors are solid. I've seen cases where a given set of RCA interconnects work fine on product A, but are intermittent on Product B due to tolerance variations. Pull the AC plug for a few minutes. (Re-Boot) "exercise" all the relays by going through all inputs/mute/volume/balance etc. I've never-ever had any issue with the relays CJ use..so it's highly unlikely this will accomplish anything. Good Luck! |

I agree with Rayoo. Unplug the unit and reboot it. It has that quirk where for some reason every so often, one channel will go to 1 and can't be raised. Unplugging the unit, cures the issue. Must be some sort of static electricity or surge issue?

I did unplug but it did not fix issue, I also had problem with being stuck on volume control number 1 and will not go up.
Thanks |

There pretty much are: "no user serviceable parts inside"
But.....there is a connector supplying power to the logic board in front, and data from the logic board to the volume/input selection relays in back. if you decide to take the top off you could have a look to be sure that connector is firmly seated. Typical logic problems of any kind, whether caused by static electricity or other, in my experience have always been cured by the re-boot. |

Ok so unit sat unplugged today, I just hooked up and both channels work can someone explain!
Maybe MR. Conrad or Johnson might chime in. This is the 2nd time I have lost the right channel and right volume stuck on # 1 and would not move! Should it be sent to CJ for a check up? Thanks Gang |

I keep writing replies to this and then deleting them because they are too rude.
Of course you phone your dealer. Do it straight away. Don't start nattering to the Internet, most of us know nothing. We are just a bunch of mugs like you. I would be on to the phone to the dealer and get him out of bed to fix it or have it replaced. You just spent a shed load on a very very very expensive preamp upon which the brands reputation rests. If they can't jump through hoops to keep you happy then what hope is there for the rest of us. Sheesh! |

Don't you think that if there's quick fix and you don't have to be without the unit for a period of time is the better option? Or that there's something that one possibly forgot to do?
Of course the dealer should see then what can be done.
