Hello,

i lately bought a Pioneer LD-S9 and are waiting to get it delivered. I live in Germany and need a Step-Down Transformer but only find options that deliver 110V instead of 100V. Is that a crucial point or would a 110V be ok to use? Otherwise would be great if someone could give me a hint to a viable solution.

Thx!!!

If you paid a lot and care, look for the correct step down transformer.

Thank you for your reply. I just bought the following Step Down Transformer:

https://www.amazon.de/ZHENGXI-ELECTRIC-Spannungswandler-Transformer-Converter/dp/B0D3KQD8LH/

It has a dedicated 100V Output, so I hope this works out ok.

I read the listing quickly, I only see 110V, I wouldn't risk it, unless it really says 100V and I didn't see it, then its fine.

This one might have been a bit cheaper, but your choice looks fine:

The problem with most of these 110V units is that they spit out much more current than listed.
I measured mine at some point, and the one rated 110V actually spit out 135V, so yeah don't risk it without measuring it beforehand.
I ended up getting dedicated 100V ones, and they measure between exact 100V to max 105V.
I'd suggest canceling the order on amazon for that chinese crap.
Order a multi-meter so you can verify output before you plug the S9 into anything.

the one I bought has to outputs ... one with 110V and a second with 100V, so I think that this should work. I'll see and report when my LD-S9 and the transformer arrive. I have a multimeter and hand and will measure the output before attaching the player ... that's for sure

As I understand it - and I in truth know little of such things - the output voltage of a transformer may vary depending on the load presented.

A multimeter test would be a "no load" test so the results won't be useful. You would want to measure the voltage when the load is that equivalent to your LD-S9.

But I think that's overkill to be honest, I would just plug in the player!

But without load it should show correct, I have some multi volt AC adapters for 1.5 to 15 volt, they all show the same voltage even
when selecting different voltages on the switch.

I'm rather wishing that one of the more technically-minded members of the forum will chime in at this point, rather than let me struggle on with my limited understanding, but I will try...

It could be that, say, a transformer with a nominal 100V output is expressing that as the voltage in a no-load condition - so it would measure 100V when unloaded, but 90V (say) when loaded.

But on the other hand it could be expressing that 100V as the voltage expected at full load - so it might measure 110V when unloaded, and 100V when loaded.

With your multi-voltage adapters, as an experiment you could add a load that will draw whatever their maximum rated current is, and see if the voltage drops compared to the no-load condition.

I wonder if it might be easier to buy a DC-to-AC Inverter designed for the Japanese market, and use that with a DC adapter you can get in Germany.

For example, this Yahoo Auctions Japan listing has a three of them for sale. These seems to be for car stereo systems, so they use the 12V as input. You could pair one of them with a 12V adapter that you get in Germany, and these devices would turn that into 100V AC.

Edit: I missed the bit where you purchased a transformer with a 100V output! Congratulations, I hope you enjoy your player!

You can swap the power supply between the S9 and the CLD-99/703/704/79. They are all the same part. The labeling on the power supply for the S9 reads 120VAC. It is made to work with either 100 or 120VAC.

I‘m still waiting to get my LD-S9 and await to get it in a week or so. In the Moment i have it here, i‘ll Open it up and have a Look at the power supply. As I Wrote, i have the Step-Down Transformer here and will measure it in the next days. It‘s correct that a Transformer normally will be pulled down a Little, in the Moment you Attach a real load.

Put in a recapped PS board from a cld-2950 and be done with it.
I have all my US players running on these
This way no more need for step-down transformer

that's a good tip. I'll have to see if a defective 2950 with working VWR-Board comes around. If I'm lucky i might very probably try to do this

I just plugged in my Step-Down transformer and measured the outputs with a multimeter without attached load (... as I'm still waiting for the LD-S9). The 100V output measures 106V and the 110V measures 115V which corresponds with the voltage that can be read from its own display. This seems ok for my taste as I expect it to dip down little when the Player gets attached. I also read that the LD-S9 seems to have a power board that is ok with even 120V, so I should be absolutely on the safe side.

We'll see

Even official 100V in Japan is usually around 103~105V measured on the outlets, you're good to go!

Should be easy enough to find in Europe.
Got like 5 hard used 2950’s trough the years mostly not worth saving because of bad repairs or shipping damage. Recap the PS just to be on the safe side and you should be good for years to come.
The PS only needs soldering for the main lead. Simple plug and play after that.

just received the Player today in perfect condition (omitting the remote that doesn't work sadly ). Working perfectly with the transformer and the picture quality made quite a nice jump compared to my CLD-D925 and DVL-909
