LPSU choices, new contender.....

[activist38]

Please forgive me if I don't answer your posts. That is because I have found it necessary to press the IGNORE member button. Six and counting! I can't be doing with the hassle. Please use/dissect  PB product before making any further comment thank you! To my ears these 'PB' PSU's sound excellent, subjectively speaking. It's just a recommendation from a satisfied customer, you don't have to follow it or buy it! BUT don't knock it - if you haven't tried it! So what if he doesn't use surface mount components, surely that's his choice and his design? It's no big deal.

I prefer point to point valve amps rather than PCB's options, that's my choice also. Knit pick on that as well if you like, be my guest, I'll just press ignore member.

Great feature that I've up to now under-utilized. 

Thanks for the reminder.

you're welcome friend!

I think it's time for me to abandon my own thread. I have made a recommendation as a customer of PB and hopefully someone will find it helpful as long as you remember to ignore the sceptics on here. The sceptics by the way have NOT tried these products or tested them so their comments are totally useless! Please feel free to talk amongst yourselves and have fun! Job done, seed sown.

Tomorrow, which is already today in the UK, Paul will be shipping me his custom/micro-adjustable turntable LPSU. If I like it, I keep it. If I don’t, I return it. 

Hard to ask for more than that. Will be fun, interesting and hopefully a keeper.

Looks like the_doc735/valveboy is back again.

I know what you mean he is bit sensitive but the usual suspects have nicely synced up with there menses also.

to all comment makers here: don't discredit products without trying them

I'm not discrediting the product. He's doing that all by himself.

so you discrediting his products? 

 

 

Not sure how saying I'd like to have a pick and place machine to allow me to enjoy DIY in retirement can be interpreted as any sort of hostility to PB's products.

 

Does he seem to make a bit of a fetish about not using surface mount components? Yes. Have at least two people I know are skilled at product design, barrows and Superdad, said there are surface mount products that work as well as or better than through-hole products? Yes. Does this mean PB's products can't work well for the price? No. Does it mean that "No surface mount products anywhere" is marketing rather than necessarily an indication of better quality? Yep.

Going by the lack of detailed specifications anywhere, I doubt that he even has equipment capable of making anything other than basic measurements such as measuring DC voltages to a reasonable precision, which any high quality DMM can do. With the DC power supplies he doesn't even supply output noise specifications.

 It's all short on detail and long on hype.

 I don't doubt that the products work, but see no reason to believe they are more than just basic implementations which will do the job with non critical applications

 With the TT voltage regulator, it would be interesting to see how well it retains the set voltage under varying load conditions and temperature variations.

I wanted to say "have you seen the Paul Hynes website?". But he is currently putting up a new website, maybe with specs this time.

I have previously seen quite a bit of detail about some of Paul's products including the topology, as well as how damn fast some of the opamps he uses in the voltage regulators are. I have previously used a Paul Hynes 3.3V voltage regulator in my DIY DAC and it is clearly lower noise than a generic 3.3V voltage regulator such as a LM3940T-3.3.

It was about the lack of detailed specifications on the website. 

 

And is a output noise voltage of 150uV low noise?

Wise @Jud likened this place ideally as like a pub. We are all sitting here enjoying our ales, and you’ve come in telling us about a new type of hops you’ve found. We are chatting about the best ways to grow hops. We talk about hops and different ales on a nightly basis. Some of us grow our own hops for ourselves, others sell the hops they grow, and others just want to drink. If that’s not of interest to you, we can continue our discussions amongst ourselves ...

Nice extension of the analogy, but with the apparent liberal use of the ignore list, he may never see it.

Aha.....maybe that explains why a few get pissed and leave 😳

My name is Paul Baldwin - I live in the UK - am a retired (not) Electronics Engineer within the Audio World.
Since I retired - I have invented and produce a host of 'Old School' Audio equipment which has been received with a smile throughout the World.
This particular post on the forum relates to a chap who has tried to say that my Baldwin HiFi low noise linear Power Supplies are very nice.
I thank this member for his acknowledgement of some products he has purchased and has used with his equipment - although he seems to have received some flack from the indigineous long term member experts who have not used or seen the item in question - shame.
Surface mount technology is useful for mass manufacturers - yet for an engineer is a nightmare to replace. Thus my 'sad' "copy" offerings are  made from solid state components which can be changed easily (by an old bloke with a soldering iron) should that be required.
This long extended post on this forum shows some lack of intuition. Certainly a less than Welcome to a new member - as I am too - just to respond to the Forum.
BTW. I do not release circuit diagrams or close up images of component values - else my designs would be copied after I have spent years confirming their design.
Thankyou for letting me respond to this post within your forum (if admin will let me)

Hi Paul,

 

Before the inevitable cynical responses start (based on the sceptical response the Op received in lieu of a welcome) let me just say thanks for joining the convo and welcome to AS.

 

I may have questions but first and foremost, welcome.

 

Cheers,

Alan

[Ralf11]

Thx for explaining why you use SMDs (if not why you advertised it as a feature - are components meant to be replaced by the user?).  There have been a lot of trolls who joined here for one reason or another (including being kicked off of other fora) so people can be a bit testy to newcomers.

That's bullshit. There's no more polite way of saying it.

[BigAlMc]

Hi Paul,

 

Two questions. One easy, one a bit more challenging.

 

I'm considering my DC power supplies currently and am potentially in the market for 2 x 12 to 19v PSUs capable of 1.5 to 3amps each. (These would be to power two Intel NUCs).

 

Forgive me being candid but your website didn't help me figure out which of your units was best. Would you recommend I consider two of the DC units or one of the Big Supply units (I assume these are dual rail?).

 

Second, more challenging, question. The Op compared your PSUs favourably to the Paul Hynes SR4. This is high praise indeed (and probably explains some of the testing responses he received) given the reputation Mr Hynes products have here.

 

Without asking you to give away your secret sauce, why should I consider taking a punt on your work? No offence intended and genuine question.

 

Cheers,

Alan

Yes there is. For starts you could try!

 

@The Computer Audiophile is this really the level of courtesy we want to extend to new members?

 

Healthy scepticism and some challenging questions are fine. But open derision and hostility. Frankly I'm a bit embarrassed by this whole thread and the reaction to it.

 

Cheers,

Alan

And is a output noise voltage of 150uV low noise?

It is  less than that of a typical LM317 etc. that many have used without problems for many years, and is still more than good enough for many applications these days. The main advantages of devices like this were their very fast slew rate, which gave them ripple rejection capabilities to MUCH higher frequencies than the generic voltage regulators.

[Neverfinished0]

Each and every unit I produce Alan is custom built as if I am going to use it. If it's wrong - it goes in the bin.
2 x 19V PSU's @ 1.5 Amps each (double it 3 Amps each) will need a slightly bigger case - One Toroidal - 2 x Rectifier/Regulation units. Custom output cables are also possible. See we aim to please
