Matt0411 Posted June 29, 2017 Share Posted June 29, 2017 Hi all, I live in Australia and purchased a Marantz 6300 from the US. This model runs of 120V and Australian has 240V electrical sockets. Without thinking, I plugged the unit in and have clearly fried something. Any thoughts as to what I could have done and how I can fix the issues? Matt.

ajxd Posted June 29, 2017 Share Posted June 29, 2017 There's very few electrical components in a turntable. Mainly the motor. You could have fried it. http://www.nodevice.com/manual/6300-235251/get125605.html Quote Link to comment Share on other sites More sharing options...
allenh Posted June 30, 2017 Share Posted June 30, 2017 This one like most Japanese decks has a transformer in it so that is the most likely thing to go first and it depends how long it lived with 240V as to whether anything after it got damaged in the process. Looking at the circuit there is a neon and a resistor across the primary of the transformer which may have also gone and there are some smoothing capacitors on the way in. The up./down and manual/auto switches are shown in the diagram in positions that don't complete the supply circuit so if you if you didn't smell burning when you powered it up and had the switches in the right position then you might have been lucky but I very much doubt it and I'd be looking at the transformer first. Unfortunately the fist rule of electricity is that everything electric contains smoke and sooner or later it has to come out. Quote Link to comment Share on other sites More sharing options...
Matt0411 Posted June 30, 2017 Author Share Posted June 30, 2017 Thanks Allehn. So, I didn't see or smell smoke. When I power it on, the strobe light is still active. Any thoughts on this? Different power supply? Do you think that I may have also fried the motor? Quote Link to comment Share on other sites More sharing options...
john Posted June 30, 2017 Share Posted June 30, 2017 Are you positive it worked prior to you receiving it? vinyl addict 1 Quote Link to comment Share on other sites More sharing options...
allenh Posted July 2, 2017 Share Posted July 2, 2017 Provided your now powering from 120V rather than 240V if your comfortable doing so and qualified it looks like your going to have to get busy with a volt meter to see where the problem lies. remember 120V will still give you a nasty tickle. If you can read 120V on the primary and nothing on the secondary then the transformer is your first and hopefully only casualty. The Neon may well still work as it's on the primary side of the transformer and a lot more robust but that doesn't mean the transformer is any good still, The circuit doesn't say what the secondary voltage is but looking at the values that are given I would say between 36V and 40 V, so if it is gone you are looking for a transformer with a 240V primary and a 36-40V secondary that will fit in there which shouldn't be that difficult to find. The VA rating won't be very high as it's not exactly powering anything substantial. Quote Link to comment Share on other sites More sharing options...
Fernando Posted October 22, 2018 Share Posted October 22, 2018 hello friend I had the same problem connect my turntable 6300 (120 v) to an amplifier (220) I turn a moment and then I heard a sound and it stopped and it does not move anymore, the light sends, I would like to know more about the fault, that was finally Did you have a solution? I will appreciate your information, my mail [email protected] regards Quote Link to comment Share on other sites More sharing options...
