My ps arrived from Pony (Express?) today. All worked out well, Pony even set the output voltage to my preference. Were there any customs or extra charges above the initial purchase price Clive? |

No extra charges though with shipping and tax/duty the original price almost doubles. Pony paid the customs charges and their declaration to U.K. customs was accurate. |

MartinT just replacing the internal fuse. Which way does the current run across the fuse? What have guessed at; from the back on the power supply towards the front? Thanks.

As you read the lettering, from left-to-right is source to destination.
Ah, you mean in the 01-A? I can't remember as I always use a meter to determine direction (with the fuse removed).

Ah. Thanks. I don’t have a meter. Sounds better already with only a couple of hours on it. Went for the Hi-Fi Tuning supreme 3 you recommended.

Ah. Thanks. I don’t have a meter. Ok, I'm pretty sure I remember the direction of flow goes from the outer edge of the board towards the centre. HiFi Tuning fuses are really good for DC work. They have an arrow depicting direction. |

Thanks. Means I have it the wrong way round. Looking forward to the boast when I change it to the right way.

Thanks. Means I have it the wrong way round. Looking forward to the boast when I change it to the right way. One theory suggests that cables and fuses 'acquire' direction by use over time. The starting direction is the recommended one but if left for long enough in the wrong direction it will swap ends. Source: Russ Andrews |

Thought I would add for any future readers. When changing the rear fuse on this PSU which is part of the IEC input. The current runs from left to right as you look at the back of the unit.

The current runs from left to right as you look at the back of the unit. Yes, that seems to be the case for all rear panel integrated IEC/Fuse sockets. However, I always use my meter to double-check. |

Looking for an alternative LPS following my debacle (above), I noticed another AE vendor selling a variant on this LPS. Slightly more expensive, and with different caps: Japan Nichicon FW series Audio Filter. Any thoughts? Are these caps better than the Rubycon ones? www.aliexpress.com/item/1005003402785289.html |

The starting direction is the recommended one but if left for long enough in the wrong direction it will swap ends. Source: Russ Andrews I certainly believe this to be true for some cables. I've been told that Chord test each speaker cable batch to see if one direction is best, and then label accordingly. And yes, further directionality is baked in through use. The labelling then assures consistency if the cables are swapped out. However, QSA fuses claim rigid directionality, apparently. |

It's really hard to know whether the Rubycons or Nichicons are genuine. My honest guess, based on their real cost, is that they are quality Chinese copies.
That tells me that they are probably the same inside, with the different models appealing to which 'brand' attracts you more.

I'm also looking at buying one of these, and in the interests of balance, I feel it's worth bearing in mind the following, when ordering such items. I ordered my 230v/12v 01-A a few weeks ago on AliExpress. Eventually it was despatched via Fedex, despite my paying for and explicitly requesting DHL. It did arrive, but on opening the box I found a 115v/18v model. I immediately contacted the vendor, and was instructed to plug it into the wall in case it had been mislabelled. I refused - "dangerous", I said. I was then asked if I could send it onto a USA address - the actual intended recipient (I actually have his name and address!). I refused - I wasn't prepared to take responsibility for customs forms etc. Instead I was asked to return it. I said I wouldn't until compensation was received for return postage. That arrived 3 days later via PayPal (minus Paypal charge). The vendor said they couldn't arrange collection from me. Three more days, and no replacement despatched, so a refund has been requested. The moral of the story: buying direct from China offers bargains, but when it goes wrong you're entering a world of pain. The risks are significant, as is the language barrier. It was interesting to me that the model sent had no serial number. It does have a CE denotation, but to be honest I take that with a pinch of salt. I thought it appropriate to follow this up, for the record. Please don't bother reading the below if not interested. I wouldn't be - but thought it might help someone down the line. I did finally get a full refund, but it was fairly tortuous. Pony Electronics Audio Store did all they could to draw it out. Basically, after requesting a refund Pony delayed as long as possible before offering me a partial refund of the item cost, minus original tracking and taxes. They stated this was the maximum possible. I escalated to AliExpress, who within 24 hours proposed a full refund, which I immediately accepted. Again, Pony delayed as long as permitted before refusing this proposal. Again, AE stepped in and declared a full refund, which actually appeared on my credit card 24 hours later. So hopefully this unpleasant episode is now over. Though saying that, I've read that a common scam on AE is for sellers to offer refunds or shipping costs via PayPal. They don't, however, just send money. They actually send it for "goods/services", which some time later are then claimed back due to "non-delivered goods/services". I've done what I can to mitigate this risk by attaching tracking details to the PayPal transaction. We'll see what happens. It might yet bite me. The situation of the taxes on this return is also somewhat vague. UPS has delivered but their site states that ~£20 of import taxes are still payable. This should be the responsibility of the receiver, but who knows if I filled in the customs forms correctly. I most definitely declared the item as a return. I contacted UPS about this, and the reply was: "The receiver was able to receive the package and may have paid the import charges to the driver.". Again, this might yet bite me. And as a final appendix, there's this recent interesting story of a man who received 11,000 customs tax charges after overseas vendors used his postal address as a VAT address: www.bbc.co.uk/news/uk-wales-65205520It would appear that many vendors don't actually pass the taxes taken onto the recipient's government. |

Thanks for recounting your experience, Mark.
I guess 'let the buyer beware' is the applicable warning for everyone. I'm also aware that I've been very lucky and never had a bad experience with an AliExpress vendor, and only one with an eBay vendor.
