Re: Longdog PSU with Lenco GL75

Been thinking about this. Now the subject seems to have moved to debating. The problem with the Ad-Hom rule on here (while it sounds like a good idea) is that it is easy to subvert. By answering the question but in a deliberately provocative and arsy fashion and repeating those posts to the point of...

Re: Longdog PSU with Lenco GL75

It's called debate. Its how you learn.
Only thing you learn by debate is how to be better at debating. You can't derive any facts by debate. You may introduce preexisting facts into a debate, but they can be and often are, defeated by a better debated but factually false argument.

Re: Longdog PSU with Lenco GL75

Fluctuation outside very narrow parameters causes death of electrical appliances. Unlikely. Most equipment is fine with 50Hz to 60Hz. Switch mode supplies don't care, and as long as voltage differences are handled, generally a transformer will be happier at 60Hz than 50. Unless the device uses the ...

Re: Longdog PSU with Lenco GL75

It would be interesting to see a trace of the 50 (ish) Hz sine wave from the domestic mains. Anyone here with an oscilloscope ? * That will vary from region to region and house to house. A better thing to measure (also carefully) is the distortion levels. Connecting a scope directly across the main...

Re: Longdog PSU with Lenco GL75

No, although perhaps I should have said, it fluctuates at the level of the 2nd decimal point, if you can hear this you are a better man than me. Have you got measurement to 3 decimal points for the long dog? Yes, perhaps you should have said that, you would have been right then. If you look here yo...

Re: Longdog PSU with Lenco GL75

It's runs of 50 hertz. This doesn't fluctuate even though voltage deos.
So you agree what you said there was wrong then.

Re: Longdog PSU with Lenco GL75

Your lenco is not voltage dependant. It's runs of 50 hertz. This doesn't fluctuate even though voltage deos. For 60 years or so lenco's have run happily without the need for speed control. Been tying to keep out of this, but yes, the 50Hz does fluctuate, it does so all the time. And IMHO, most of t...

Re: Having a Ripping time with HDCD.

HDCD was a system introduced by Microsoft in the late 90's
Just to be precise. it was created by Pacific Microsonics in 1995, and then purchased by MS in 2000 which just about killed it.

Re: Is it OK for the government to knowingly break international law?

Can anyone please to explain to me, how and why the UK Government's approach to breaking the law discussed in the article quoted in the original post ISN'T a sensible pragmatic solution? I'm happy to admit that I'm no expert on International Law and the full complexities of Brexit. Maybe I can lear...

Re: £500 Valve amps

If you are up for this sort of DIY, you'll have a reasonable chance of making yourself a (near?) World Class (in the midrange) amplifier for that sort of money. You would be hard pressed to find a pair of output transformers that were anywhere near world class for that money let alone the rest of t...
