Just that one time lol ..and I'm done messing around with sockets now ..everything's how it should be

Re: Wall socket polarity... (mine was reversed )
You have problems with beakers and getting proper readings from the socket, and you still blame the polarity for the sound differences?

Re: Wall socket polarity... (mine was reversed )
No..no problem with breakers ...I switched the wrong (my kitchen's) one off..that's all
...& the reading from the socket did'nt work because I could'nt get the screwdriver/tester into it properly. My floorstanding speaker (for my stereo) is right in front of that socket and while it's easy to get a plug into that space the screwdriver/tester did'nt really fit & I don't think it made contact properly enough for a reading. (I don't like moving my speakers since I have them correctly angled/"tuned" to my room) In any case my plan was not to touch the wires anyway (unshielded parts) but I got careless..
and yep ....it's definately polarity that's causing the difference with my amps..pretty sure about that

Re: Wall socket polarity... (mine was reversed )
I hesitate to say it but ... this thread is starting to remind me that some "audiophiles" pay thousands of dollars for a pair of RCA cables and power cables. No further comment on that other than to say that I went into the wrong line of work ...
)I hesitate to say, but.......Humans CANNOT hear phase.
Yes it Can Be/Is a safety concern.
I hope you can get your Hi-Fi retuned to your room.

)Not at all ..my mind is clear
Not at all ..my mind is clear
I transpotred it to another room which still has a reversed polarity socket..and viola! Crunch is back to 1/2 volume..
:smack: Any readers having issues on credibility? :33:...................................:wave::flush:Turns out I'd switched the kitchen one off instead...should've been the one next to that. Did'nt realize that till I decided to double-check a while ago after reading the last couple of posts here
The thing is I used one of those tester/screwdrivers before I started to make sure the socket was dead & it did'nt light up (was'nt working maybe or I did'nt make proper contact..). That's how I thought I had the right circuit breaker..

Re: Wall socket polarity... (mine was reversed )
Honestly, the most basic thing with floorstanders (or any speakers) is that you don't just throw them where you please. Everyone positions them a bit and/or angles them in a bit till they sound tight/ in phase. Nothing "audiophile" about that at all
@ zzmore: Maybe humans can't hear phase but they definitely can hear halfway drops in volume/increases in presence/brightness/lowering of noise..ie...the effects of wrong phase on their tube heads
..and my hifi's fine....still tuned to my room since I did'nt ever move it...thanks

Re: Wall socket polarity... (mine was reversed )
Not relevant to my comment but I think I hit a nerve. So, how much did you pay for your RCA interconnects?

Re: Wall socket polarity... (mine was reversed )
I have never met Anybody that could hear the difference between:
out in out in out in out in out in out in out in
vs.
in out in out in out in out in out in out in out
People SAY they hear all kinds of things, including:
Phase
Dielectric
Solid vs Stranded
Paper vs Plastic
Three feet of 18 AWG vs 16 AWG
etc etc
The truth is what you can pick form a blind test.....10 times out of 10.

Re: Wall socket polarity... (mine was reversed )
)There's a difference between hearing the phase of power itself vs the phase of power causing the amp to function differently, at which point you're hearing the function not the phase itself.

Re: Wall socket polarity... (mine was reversed )
NPN and PNP transistors will function wildly differently (or not function at all) depending on how it's wired into the circuit. It looks like there's a couple transistors on the board there.
There's also a couple ICs, possibly for distortion, so those might be affected by the phase of the input power.
And, yes, a tube amp's power gets rectified, but you still have to reference which side is neutral (which should be at or very near 0V constantly) and which side is hot (which is the actual alternating current).
Also, depending on how the amp is wired, the ground plane may depend upon the chassis being connected to neutral as a reference, which also introduces a danger. If the hot is connected to the chassis you could get a good zap. But it would also induce noise into the signal (which the OP complained about). The phase of the noise won't change but the phase of the signal would flip, thus things would be canceled differently.
I'd have to refresh myself on electrical and electronics stuff I haven't looked at in quite a while, but I'm at work and I don't want to get fired.

Re: Wall socket polarity... (mine was reversed )
^^^ what he said :lmao:
Which ones? ...the solid 24k gold, single strand, quadruple sheilded, oil-filled, uber-reference ones or the single crystal UPUOFC (ultra-pure,ultra oxygen free) copper ones with the diamond encrusted RFI-deflective outer sheild? I always rotate between those two according to lunar phases/tides.. (..or there goes my tone
)

)Re: Wall socket polarity... (mine was reversed )
I am Not looking to make a big argument out of this, but.......nobody was talking about rewiring any of the solid state devices. They run on rectified DC....naturally, if you turn a diode around (tube or solid state) they will not function properly, but that is not what happens when you swap Hot for Neutral at the mains.
Your warning about what can happen with the chassis going Hot can never be stated too many times. Bobby Z has a good Youtube video that demonstrates what happens when a "death cap" goes bad.
And again, I am not making excuses for somebody being careless inside an amp they are working on.....but the whole Hot/Neutral thing can lead to the fuse being pulled, but the power switch still being Hot on one side. All kinds of bad things CAN happen. For safety's sake, the Mains should always be wired properly. I have seen countless amps with the wrong, or no "fuse" in the fuse holder, and just as many power cords that have had the ground lug pulled off. I always install a new 3 wire male end, and include a One Dollar ground lift adapter. That way, the player can Choose to be safe whenever possible
The Mains phase is important, I am just not convinced that any of it's import is audible.
good luck
