Paul Hynes SR7 and SR4 Build Calendar Thread

[austinpop]

I just wanted to pass along the fact that Paul's standard PSU line, that until now comprised the SR-4 model, has been expanded to include the SR-5 in a few standard configurations, with the first batch shipping this month. I knew this was in the works, but learned of its operational status when a local friend of mine, who was looking for a high-current 15V PSU for his iFi Pro iDSD DAC, inquired.

 

Please note: I have no firsthand experience with SR-5 units. My friend did place an order for a SR5-15F, so when his unit arrives, I will certainly be borrowing it to listen!

 

I asked Paul if it was OK to post details here, and here are his comments:

 

Of course you can post about the SR5 on the AS forum. The information
you have is current. I would appreciate if you could state that
enquiries should be directed to [email protected] as the SR5 is
now part of PHD Ltd product range and I would prefer not to have people
e-mailing me with sales enquiries as it distracts me getting on with the
outstanding custom build orders. I only provide technical support for
the staff at PHD Ltd now and do not get involved with running their
business (PHD Ltd is shortly to morph into a workers cooperative and
they are now in charge of their own destiny).

 

Here is the info. The contact email is [email protected]

 

SR5 power supply information sheet 22/08/19

The SR5 power supply is now available alongside the SR4 via Paul Hynes Design Ltd.
The SR5 is being manufactured in batches of five units per month initially with the first
batch available during September.

The SR5 uses the same ultra low noise high performance discrete component voltage
regulator as the highly regarded SR4 and SR7 power supplies. The SR5 mains
transformer is configured as a balanced mains isolation transformer to provide
exceptional mains born common mode interference rejection like the SR4 and SR7 power
supplies.

 

SR5 chassis dimensions – W = 224mm, H = 90mm, D = 226mm

The following specification options are available :-
 

The SR5 with a fixed output voltage up to 12v are all rated for 6A continuous output
current and 30A transient :-
SR5-03v3F
SR5-05F
SR5-09F
SR5-12F
 

The SR5 with a fixed output voltage of 15v or 19v are rated for 5A continuous output
current and 30A transient :-
SR5-15F
SR5-19F
 

For the switched output voltage options the continuous current rating should be restricted
as voltage settings are reduced, due to the increase in voltage across the voltage regulator
output stage, which generates more heat in the output stage. Due to the finite thermal
capacity of the chassis the current de-rating should be adhered to, to avoid running the
power supply at high temperatures. Transient current delivery remains the same at all
voltage settings and this is typically > 30A.

SR5-12S switched voltage settings and continuous current rating for each setting :-
5v – 2.4A
7v – 3A
9v – 4A
12v – 6A
 

SR5-19S switched voltage settings and continuous current rating for each setting :-
9v – 1.8A
12v – 2.4A
15v – 3.3A
19v – 5A

Does someone have prices for the SR5 series?  And what cable options are available?

Perhaps you should email [email protected]

I'm supposedly build #24.  Hmmm...

Are you sure about this ? Back in June 2018 I stated my number in the SR7 thread and you did not react to my post, on the contrary you seemed to like it

 

Every 3 or 4 months I feel like cancelling my order though....had I found a drop-in alternative to a dual rail SR7 (no bigger, etc....), I would have jumped on it already

I was thanking you for posting the updated scheduling information for your build.

 

When I originally placed my order, Paul told me that I was build #23.  Later, he told me it was #24.  Since then, we have always referred to it as #24.  I have never attempted to reconcile the difference with him.

Another mystery to be solved.....

Is PH back in business?  Sean Jacobs just emailed me with photos of my new 6-rails LPS.

[auricgoldfinger]

He has shipped one or two custom SR7s this year.

I'd love to see those photos if SJ is OK with you posting them.  Please also share your specs for those 6 rails if you feel comfortable doing so.  Thanks.

Sure.  I had to wait 3 months for mine, and probably was lucky with the timing of Sean's schedule.  I think Innuos keeps him busy with builds.  The 4 GX16 outputs are for ATX (3 rails), EPS, and two 5V for accessories.

 

 

From Sean:

"The transformer uses an over-size core, around 650-700VA, some of the output windings have the 2 wires terminated at opposite sides of the transformer - hence the unconventional wiring loom for the transformer wires, it worked out neatly enough though I think."

How many amps do you have for EPS12V and for the two 5V accessory rails?  Did you buy cables from Sean as well?  I bet you're excited!

I'll have to dig back in my notes for the amps.  I remember asking him for more than I needed.  Sean made cables for the two 5V rails, but his contract with Innous would not allow him to make the mobo cables.  I just sent the pin assignments to Ghent for those.

Hmm I just noticed we're in a thread about SR7/SR4 build calendar.  My apologies to @auricgoldfinger for going OT.

[Darryl R]

He had asked me about SJ when I ordered it, so I'm sure he'll like the photos.

No worries.

@auricgoldfinger Other than Build 15 has another SR7 shipped this year?

This is what I was told...for what it's worth.  The owner of build 14 is unknown, so we have no independent confirmation.

How fun, the only tangible I could get by e-mail from Paul this year is my SR7 build number, and guess what, it's build #23

 

So it's about time we get a nominative list with number and names (can be AS user name) from Paul.

This situation is turning nasty...

Good luck!

[your momo]

You mean for Paul's reputation ?

 

Since delivering over late and being sub-optimal at prioritizing tasks are already known limitation of the man.

 

It's prefereable we don't have to add swindler in his CV, so yes expectation is that he publish the list of remaining SR7 build and alias.

I was originally build #14 but but was moved down to build #15. Interesting.

IIRC, he has already declined to provide such a list.

[auricgoldfinger]

@TopQuark How are you enjoying your SR7?  What are you powering with it?

[guillaume31]

It's clarified now, 20 months after the build schedule has been defined, I just found out I have Build 25 🙄 Everyone moved by 1 rank due to a "forgotten" order apparently (I had never been informed)

 

I am now looking to have my order taken over. I asked Paul for names of potentially interested customers but if anyone wants to join the queue instead of me and have the pleasure to experience awful communication along with very poor customer-focus, feel free to contact me (my order is for an SR7DRMR2 but this can be changed I think)
