FYI For Pioneer Owners...

Ok. Now it makes sense. If it's a US only model, no need for the voltage selector. It's a good thing you're here to help out all of the newcomers like myself EW!
 
Thanks for the info--EW

I apprecite your information. My QX-8000 Quad Receiver is one of my most prized possessions and it has a multivoltage selector. It was set correctly at 120 volts! I just got a smaller version of the 8000 that I did not know of--a QX 4000. Kind of a cutie :) It is a US model. But I checked her for the voltage issue :yes: She has a good FM section. See my post on this receiver.

Thanks again EW!!!

I have an SX 3800 and the voltage selector is on 110V. The receiver is working and sounds allright - no problem. I do plan to change it to 120V. A few months ago I purchased another one of those Epay gems described as working great. It was a multi volt euro model Technics and the selector was on 110V. No relay at 110V setting so I switched the selector to 120v. Now all I get is loud hum over the signal, oscillations and protection kicking in at low power. Works great you know. :thmbsp:
 
I got a 1280 here, and it does not have one. Pioneer put the selector on the outside on most of them, so if you don't see it, it's probably fine.
 
I bought a SX 1050 from Oaktree, Not knowing anything about electronics other than the sound I wanted I was not going to Ebay after seeing friends get burned. Paid a lot but got good service, a real nice all original untouched unit, and a warranty. After using this unit for almost a year, 8 to 10 hrs a day I noticed it is set on the 110v. I call Oaktree and they do not seem to know what the difference is or that it is anything to worry about. So now I have found this forum and am not too happy after reading the warnings of EchoWars who apparently knows these electronics very well. Can anyone explain to me what damage has been done to my unit and what components get damaged? Thanks

Does it have a setting for 120V? You didn't say... If so, change the plug to that.

The most likely casualties of something like this are with the voltage regulator. It has to deal with a higher incoming voltage, and thus a lot more heat is generated, and the capacitors are running close to, or over their rated voltages.

Like I said, not all units have the plug that allows for different line voltages.
 
Both my sa-8800 and tx-7800 were set to 110v when I got them and did my usual clean-up/checkout routine on them so watch your arse. Both of these are marked with the <ep> logo, meaning they were sold in a military PX. I guess when they were brought to the states the previous owner didn't know any better.
 
Geez thanks EW my SG 9500 was set at 110, after I switched it to 120 it actually sounded better with the Neil Young cd Praire wind running through it. better bass.
Do I have to change the fuse also to a different amperage?
Cheers Wolfgang
 
Thank you, Yes it does have the 120v also (110/120/220/240) and is now at that setting after initially reading this thread. I wish it would have been set correctly when the unit went thru all the testing they do but after talking to them I do not think they even realize it is a problem. When the parts that are damaged by this quit working are they replaceable/ repairable? Is the transformer affected? What components failing cause a unit to be terminal?

I know a lot of these multi voltage units are military PX and after researching world voltage standards see that a lot of countries with US bases do use 110v so these were probably never changed when they came to the US. Also I read that not that long ago (40+ yrs?) the US standard was 110v. An electrician told me that with resistance in household wiring that it is not uncommon to only have approx. 110v at an outlet but that doesnt reassure me, I used this thing all day everyday for a year with it set wrong. :worried:

Very interesting forum. I am glad to see I am not alone in appreciating real tone and power in receivers. I bought a Yamaha RX-777 a couple years ago after my SX-838 started popping and was told it couldnt be fixed, new is much better, etc. After a couple hours with it I was so dissappointed, no bass, cold,sterile tone with no guts.
 
If your house has 'resistance' enough to drop the voltage 10V, there's a serious problem with the wiring. :yes:

Any issues that could arise from overvoltage are fairly easy to repair for a competent tech. Overheated pass transistors and capacitors are the usual victims.

I guess hes not a very good electrician, If I need one to work on my house I'll try somebody else.
Thanks for the info on overvoltage. I'll just enjoy my unit and if it quits then I'll deal with it, at least its set correctly now. If I had never paid any attention to that selector I would never have known and had all this worry. Ignorance really is bliss!
 
Thanks EW, my SX-828 was set to 110. While setting it to 120 I notice that it not only has the 110/120 and 220/240 it also has a 130 setting. Then while checking all the other receivers and various pieces of equipment I notice that the rating on my Yamaha CR-600 is 117v. I would assume that the 3 volt difference would not hurt it as long as I am not driving it hard. But on the 828 would setting it to 130 let it run cooler (sacrificing the higher output). Just curious.

Would one of you 838 owners post a picture of your voltage selector? Mine doesn't seem to have one and I just want to be sure...

(thanks in advance!)
 
I just checked my 7800 and my RG-1 both set at 110V Thanks for the heads up chaged both to 120V, My 1010 and 9900 are out for repair but I will check ALL my other gear? I wonder how long they were set at 110V? TOO LATE now!!!!

If the Pioneer ID tag says AC 120 VOLTS.... then you will not have a selector, yours is 120v only. My 838 does not have one, it was bought new by my Mom in Raleigh NC at a hi fi store in 1975.
I do have a friend I just called who has a 838 he got from a serviceman that is 110/120/130/220/240.
Used to see a lot of great hi-fi gear around here with all the military bases but the 70's stuff has pretty much dried up.

Like Jim says, they aren't all multivoltage units...

Leave the 828 at 120V. It is possible that the regulator might not be able to do its job properly if you set to 130V. The Yammie will be peachy at 117. :thmbsp:
 
Hello, I recently went to move my Pioneer DT-555 and the voltage selector popped off. I think my kids tripped the cord and made it fall.
Have you ever had heard of the voltage selector just popping off?
Getting a replacement?
Should be some sort of metal on that rotator to set the voltage? I cant find any of the clips. Might have to hard wire it
Thanks, any help is appreciated.
