Audiophile Power Regenerator Repair (PS Audio Power Plant 300) 

Low oxygen copper in the windings - you can hear the difference.

You put far too much faith in my local power company

NAILED IT !

😂😂😂 No, you are wrong. The "thing" will do a better job than before.....

😀😃😄

true hater in his natural habitat! Says the arm chair audiophile that does nothing but look at what he can’t afford or have.😮

Good thinking, this would be ideal for Mat. Didn't occur to me when I was watching the repair.

Who?

Hi Mark. I must say that watching your videos makes me envy the way you tackle such a wide variety of devices. You are a true professional. It's great to see you are able to put your hands on all the parts required and your test equipment is so comprehensive. Keep up the good work. Personally I would like to see you tackle one of those horrible little Denon mini reciver/cd players and their ilk.(model numbers escape me at this moment) Kind regards Allan 😃

exactly what I thought!

i was type typing the same thing when i seen your post super odd.

@@RetroTuna nah you HAVE to replace all the capacitors with space-qualified, anti beta radiation ones, and they have a gold foil / kapton dielectric layer between their vaiorus hiss and click sonic-proofing layers, thanks for the tip I just realised I can use Kapton tape for picture framing as it wont melt in Thailand :-) (PS we got plenty of snakes here)

I think someone was in this before

The snake oil only comes with NEW gear, it's factory installed. Once opened the magic is gone.

There is a guy here who SWEARS that the kapton tape makes the transistor run hotter, giving the audio a "warm sound" with more "width" and "depth". ROFL My speakers at home are connected to my amp with old leftover ethernet cable, and I don't care.

Yes, a double blind test is the true measure of whether it makes a difference.

But what about my depth of field getting bigger? And my warmer punchy round bass? And silky yet transparent mids? And the smooth yet accurate treble? And my stereo field widening? And the fact that my tubes last longer? My $1000/ft speakers cables are at 90• bends for perfect sine wave conductivity. And yes I did make sure my power cables cost at least $5000 and they are most definitely directional. This magic box is a MUST in any serious system. Get with it, bruh!! /s

@@dh-_1011 Haha! I tried one of those directional power cables and it sounded amazing, but it wasn't worth the trouble of having to switch the cable ends around 60 times per/sec, so AC current could flow both ways.

@@gordthor5351 It’s a labour of love, it’s all about tOaN!!!!!!!!

Don't blame me, I just fix them...

Correct

Seems another piece of audio confoolery from Paul McClown and PoS audio.

the more you spend, the better it sounds, right?

@@nudebaboon4874 go to boulder and check out their stuff, it sounds amazing

That's generally the opinion of Amir from Audio Science Review. And mine too. PS Audio stuff is vastly over priced .

was that relay powerful enough? it didn't look meaty enough.

I personally have experience with these "things", and know what positive improvements I can demonstrate in terms of noise-reduction and clarity. Have you used one are are you just convinced they are not worth it? If so why, pray tell...

@@vicweast Let's just put it this way, I've never come across an audiophile who has any knowledge of electronics or physics...

@@vicweast If you want to fight, you can check out the Audio Science Review. Basically, it doesn't make any sense unless your device's circuitry doesn't use DC, but directly AC. Any normal circuit's DC side should not be affected by AC in any way unless there are major power surge or blackout.

@@mattparker8747A good example is the late Siegfried Linkwitz (of Linkwitz-Riley filter fame) was a dedicated audiophile and an electronics engineer who designed instruments (Spectrum Analyzers etc) at Hewlett Packard for many years.

exactly this ^^

Audiophiles' brains and wallets don't work that way. They'd strap a tortoise to their amps if someone wrote a convincing article it would help with sound quality.

@@chimpana I have a giraffe on mine, I read somewhere it improves the high end.

nah the company should have made Tempest Grade isolation devices (for that ultimate red-black transition) and filters then they would have made zillions from the military

@@chimpana I can think of a number of examples, but I think my favorite so far is audiophiles who use little wooden stands, like tiny 3” telephone poles every 2’ propping up their cables so that their speaker cabling and patch cables (oh, excuse me “interconnects”) do not make contact with their carpet or other flooring, because…that’s…bad. The person I first saw doing that spent 30 min trying to explain to me how much better his system sounded after this modification, and why, in pseudoscientific terms at least, it made such a huge difference to use his wood stands. It’s bizarre and hilarious. It’s woo-woo, almost like a set of supernatural beliefs. Makes me kind of sad, this sort of anti-scientific, non-evidence based approach, but I think the main thing that really drives me nuts about this is that it’s not even necessary because there’s so much great sounding, inexpensive consumer/prosumer and pro-audio gear available! I am a musician, producer/sound designer (and so is my brother), mostly video game music/soundtracks and sound effects, so I obviously enjoy good music, played on a system that is adequate. Audio engineering has long been an apprenticeship-based profession, starting with the “tea boy” role in older studios (or the “roadie” role - in touring and live concert production) so it used to be a bit more difficult to access the knowledge needed to work in our field without some sort of hands-on training…but these days, there are so many ways to learn about the concepts behind sound engineering, so the knowledge is easily available to almost anyone with internet access. I hope more “audiophiles” will realize they don’t even need all this expensive, often absolutely useless and absurd crap to hear their favorite recorded music, faithfully reproduced.

I was about to ask, despite the obvious irrelevance of the mains line condition once it's rectified... Wouldn't an UPS do the same thing... Maybe not be able to switch the frequency though.

I think he got a deal since it’s used Einstein.😂

Its not actually the switched mode bit of the power supply that does that, its the rectifier, which has been used forever. SMPS can inject distortion into the net, just not harmonic distortion. Nowadays, there is more regulation on the distortion a supply is allowed to make, so I would imagine it would only get better, as long as we don't collectively buy unregulated imported electronics, which tend to omit most of the improvements, like power factor correction and EMI filters.

Yes, I get a nice waveform out of a ferroresonant converter, which also has a nice advantage that rectifier diodes run cooler due to the flat topped waveform, and it makes for a really good mains filter as well, surviving a few cycles of drop out with no hassle..

Almost as if audiophile kit is expensive snake oil!

Mark could've done the owner a huge favour by just wiring the input mains to the output mains and bypassing the whole stupid thing, then charging the owner $1k for the repair. Massive increase in efficiency, reduction in fan noise, etc, and the owner still gets a nice heavy expensive brick thing to feel good about showing off to people.

You have to account for the thickness though. If the silicone pads are more than 16 times thicker than the Kapton tape, higher thermal conductivity won’t help.

He is just as funny when he gets zapped. He even swears sometimes.

Num num num num...nummy.

And even then it won't do anything.

@@Wizardofgosz Yeah you're right, if the steel mill is chomping whole cycles out of your mains then this contraption probably won't even work and your flickering lights are likely to be a bigger concern.

Try to make a voltage divider and put your mains out into a scope, and you will see how distorted it is.

@@qddk9545 Sure, but distortion of the mains doesn't translate into distortion of the audio.

@@qddk9545 Yes? And? Then this miraculous thing happens. The AC gets rectified and FILTERED through this thing called a POWER SUPPLY, and the power comes out as clean DC. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-12T7JFLGlf0.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-II07bFlteig.html

I don’t think so I believe he likes to work on his own equipment he’d want any of his secrets getting out into the world.

I used to watch his videos too. But then I realized that if you're not using PS Audio components or audio cables that cost $100/inch, your system is crap.

I can't watch him, he comes across as disingenuous. He's clearly a competent and knowledgeable engineer who understands the principles by which good sound is produced. Then he goes on to feed the rumours and claptrap circulating in audio circles, upon which he sells vacuum tube amplifiers and power regenerators. He knows full well this contraption won't make any difference to any well designed audio equipment. If this made a difference then the equipment it feeds has a poorly designed PSU. He pushes flawed concepts, like conflating the purity of the AC supply with the purity of the audio signal. He sells nonsense hyper expensive power cables and snake oil mains fuses. It's sad and I can't watch the guy, he's trading on the ignorance of fools who have more money than sense.

@@jamesrindley6215 When he did a tour of his home theater setup he doesn't even us his own stuff. He uses Emotiva amps because he "doesn't have room" for the monster size PS Audio components.

@@domosautomotive1929 Yup, and he no doubt knows full well that all correctly functioning amplifiers sound identical.

Second to none, after the Metcal desoldering tool. Of course not many people can afford Metcal prices, and it requires a seperate compressor.

Mica insulators will give a grainy, mineral sound. The audio characteristic of silicone is too soft and rubbery. Kapton will produce a clear tight sound with solid bass and treble. Unfortunately beryllium oxide will cause severe attenuation of high frequencies and make your high end setup sound like a cheap telephone. Of course diamond is the superior heat transfer material of choice and produces no noticeable coloration, it is the best if you can afford it. Vacuum tube amplifiers do not require heat transfer pads. That is one of the reasons they have a superior sound

@@gordonwelcher9598 Spoken like a true audiophile.....Cough!

🤣

@@peterallen8413 At low frequencies the heat is produced in waves. Inappropriate transient properties of the heat transfer material will cause the bass to be severely distorted due to thermal effects on the output transistor junctions. Nonlinear dielectric loss in the stray capacitance will affect the high frequencies. Tighter clamping will make a noticeable improvement in sound.

@@gordonwelcher9598 I'd love to see a double blind test for that woo woo!

says the troll!

Paul will tell you straight up that valves colorize the sound. If that is your preference they have a product. If it is not your preference they have a product.

A DC ADC converted AC into DC bits AC would be converted to AC using a DC rail.

I am thunderstruck.

Never thought of this, thanks! Of course do this only if I’m sure the semiconductor is faulty or else I’ll snip off a good one n can’t test whether it’s ok or not

Do not think the amplifier runs at mains, likely around 70V rails, with one power transformer doing the input and the other 2 the output sockets, each separate.

Don't trust audio engineers to get normal electrical safety standards correct 🤣

​​@@ivolol How dare you!! I'm shocked, shocked!! (Apologies to Claude Rains). ⚡⚡😂

I was concerned about that - a quick web search suggests there are different grades of Kapton tape, with Kapton MT and MT plus being thermally conductive and electrically insulating, whereas Kapton HN is just electrically insulating. Don't know how you tell them apart or what type Mark was using. If the thermally conductive types are as good as mica or sil-pads, I'd be tempted - quite convenient.

Kapton and mica are superior thermal conductors to silicone pads. They should however be greased on both sides.

i agree!

Get em from Paul Mc Gowan.

He has many other interesting and satisfying performances, stay tuned. Loved the audiophool bits, interesting and entertaining. I have seen and read of such things and find humor in it, although many are quite vexed.

no

Seems illogical to take the energy from the outlet, reduce that energy by powering an additional device designed to somehow to improve the performance even though total energy is reduced and possibly restricted, passing through myriad components. I would favor the "less is more" philosophy. Fewer components, less complex circuits, fewer possible points of failure, fewer components to fail. The KISS principle.
