I'm thinking that 20+ years ago it was probably set to 117 by you or whomever you purchased it from, if not by the manufacturer. I took a look at its manual, which can be found at if one is registered there, and it is described as having switches located behind a removeable part of the rear panel which allow the AC voltage it is operated with to be selected between 100, 117, 220, and 240 volts. These cautions explain the real value of power conditioners that mitigate input voltage variance to our expensive I see in one of your other posts that your Accuphase preamp is apparently a C-280. This is because in analog electronics, some power supplies are crudely regulated, counting on line voltage to stay relatively close to design and working the filter capacitors very hard without voltage regulation. Then, there is also the issue of filtering capacitors running over voltage tolerance, and over-heating and bursting or catching fire. This heat leads to premature failure and possible catastrophic failure or 🔥 fire 🔥 hazards. Over-powering a linear power supply causes rectifiers, ballast resistors and regulation circuit power transistors to run hotter than they were intended to. Depending on regulatory requirements in electrical codes, they may have specific requirements for switching the hot -and- neutral wires, fusing and depending on mains voltage and sometimes frequency differences in some parts of the world, the primary windings and magnetic circuit in the core of the power transformer will be rated for different voltages and frequencies. Most audio gear is made with different transformers for different markets. You would need to check the labels to be certain.Īs Al wisely pointed out, the power supply in the CD player is likely a linear power supply, and designed to operate within specific tolerances for the target market. Geoff: Modern switch-mode power supplies are often auto-ranging as far as input voltage is concerned. The higher the pressure (voltage) coming in, the faster the dam fills, the easier that is.

We want the dam full at all times, to help keep constant water pressure coming out the other end of the hose.

ONKYO CD PLAYER SAYS 100 VOLT AC MODS

Which they do, just never as good as we'd like, which is why power supply mods and things like dedicated lines, power cords and conditioners matter so much.īut remember I said it was not just wrong but backwards? I'm gonna use the usual water metaphors here. The idea is the caps, in storing the power also filter the noise. Whatever the incoming voltage, hardly matters, because it is gonna be stored in caps anyway. The challenge with regards to incoming voltage isn't the voltage per se, but the noise riding on the AC line. The challenge in building a really good regulated power supply is in maintaining constant voltage in the face of wildly varying swings in demand. This is so far beyond wrong its backwards! The voltage regulators in the DC power supply are working their butts off trying to maintain a constant designed rated voltage.

ONKYO CD PLAYER SAYS 100 VOLT AC TV

Did the same thing at my parents house when I set up a stereo system in their living room (no tv there either).Yes it works, but the life of the CDP will be shortened. It doesn't even have HDMI, but it does have buttons. I am using an old DVD player in my main system without a display (tv). DVD players can do the same thing for less. A dedicated transport can cost around $500. To sum it all up you will get the best quality of sound from your CDs using a transport and a DAC (for the least amount of money). Unfortunately at $700 it is more than buget of $600 not knowing how flexible you are on that.

Some CDs have the polarity reversed during playback. It has one nice feature for CD playback: polarity inversion. I would use that and look into a Schiit Bifrost2. You said you have an older CD player with a toslink output.

The other reason I suggested using a free or low cost DVD player was that you could spend more (or all) of your budget on a better DAC.

The first one is for other people searching for a CD player so they can have a "more rounded" list of options. I understand your need to keep things simple. Sorry about derailing the thread with the DVD/Blu-ray player idea.
