Thats what it says..why is a Japanese unit ,with the 100v plug,using a 120v board…which is what is confusing for me,,…your answer is part of what I wanted to know…
I recently picked up a Japanese CLD959 off ebay(from the US) ..$217… its in the rack ,so I dont have pics of the board..a few issues…all fixed butt one….it has a 100v power supply and someone changed the cord to 3 prong 120v..yet the power board is still 100v…..Im using a converter on it….so someday,hopefully, ,when I do the NR mod and attempt to fix the analog output ,I’ll take a pic of the 100v board and ask again,,,,..or swap it with my spare 99… This is another example of what confuses me (easy to do) this board is from an EAD/TV..its 250v..krbahr said it was European..its in my repair box, used 120v from a 503 to replace it..

I apologize for the vague ,dumb questions..my knowledge is minimal .Im trying to gather as much as I can…like the comment I mentioned about the S9..krbhar comment led me to think of one members grip ring listing on EB (laserparts) of the S2/S9…little tidbits can give one a Eureka moment…saved me wasting money on an S9..
Just for general info..might help someone.. More on the 250v board..krbahr mentioned it had a jumper to change voltage..I think he meant this(see pic)…he didnt respond my return post, to my post ..hes spread thin ,answering so many questions.. Krbahr “The top one is the US power supply and the bottom is the European power supply. US uses 120V and Europe uses 240V. Outputs are the same. The European may have jumpers to make it work for 120V, cannot really see the connector by the two large caps at the input but that is where the European unit could have the selector connections for 120 or 240”.

When you actually have a 100VAC PS and you plug it into a 120VAC outlet the voltage difference isn’t meaningless. It may cause the PS to fail sooner. This is the situation you have with the 959. I’m not saying it’s guaranteed to fail, it may live forever. I’m also not saying that it will last longer if properly specced. My CLD-99 failed a PS and it’s only ever been used in the US and Canada. HOWEVER! When you have a 120VAC device plugged into a 120VAC outlet (which is what you have with the HF9G) everything is fine and it would be pointless to change anything. The odds of the differences in the grounding/primary side aren’t likely to ever matter in any way.

Changing power supplies like this is just asking for trouble. I remember reading about some who upgraded things in DVD players and it changes the power class from something like class 1 to class 2 when adding ground plugs. Since you are trying to change rather than buy a voltage converter you are just asking for trouble, and when you go to sell the player in 6 months when you get bored of collecting LDs you can't sell the player without disclosing this has been massively modified and could start a fire. Good luck

In this case it’s ultra pointless work since you’re swapping in another item that does the same thing. While the odds of messing something up are low, the odds of improving anything are literally zilch. It cannot make anything better. Just trying to gain knowledge ..electronics wise…Circuit Boards wont last forever ..the more I know ,the better..and much contradictory info on lddb..like what to clean lens with,.yea I know…one of many..Ive read where some think using a 100v player on 120v is bad for the unit.. Anyway../Thanks for your help signfzeta… Enjoy your Turkey..rein-o…well ….

When I get Bored with LDs and Players/Transports?…when do you think that will happen?..you wanna make me an offer? 18 working players .2 with minor issues ,plus 2 Im close to fixing ,1 thats dead for good(the 7020) And 2600 LDs ..its a new shelf unit I built and is a work in progress See Pics I love the picture of your cat, looks very happy and cute too
