PSU1 Constructors Series Kit

It's been the first time in a couple of years that today I've built some of our PSU1 power supplies.


(photo of the 230 volt ready-built version)

Although I'd designed it in the first place and then slightly redesigned it again in 2004 to obtain CSA(UL) and IEC safety certificates, John has been putting them together for the past 2 years. I'd just about forgot how to do them in that time.

So it was a bit like trying to fathom out a DIY project without any instructions, I thought, and then immediately the thought of offering them as a kit sprang to mind.

The case would come pre-drilled/machined to save the frayed nerves of anyone who can't stand fiddly shaped holes like that required for the mains inlet - in fact, its position is important from a safety aspect, so best we machine that bit for you.

It will still be a challenge though: It's safety and ultimate performance will still hinge on good construction skills but most hardened kit builders should not find it a daunting task - I guess many will find it a piece of cake!

The kit will feature the latest tweaks like the UF4000-series discrete bridge rectifier which replaces the bridge rectifier unit (this change was done sometime last year).

The PSU1 is one of the best "sounding" linear audio power supplies on the market, suitable for single rail use. It gives out 24 Volts DC (regulated) and is conservatively rated at 200mA to ensure it keeps its cool, but will deliver far more to satisfy short duration transients.

Available in 230 and 120 volt 50/60Hz versions (the 120V will work in Japan).

More info to follow.

Definitely interested if postage is a little more sensible than 40 GBP.

It may be much safer to use "normal" post on kits than it is on equipment. We may offer both options.

The kit website will be http://www.diy-audio-kits.com but at present there's nothing there to view - working on it.Geek

Fair comment.
I must admit that paying postal insurance seems like a sophisticated version of paying bribes to officials to ensure that they do what you have already paid them to do.
Perhaps I am being cynical in this.

You are not being cynical, just pointing out a fact that we as consumers put up with because we are fools I guess. Same goes for tracking and delivery confirmation. Ouch

Terry Gilliam has done many a film on the subject ranging from the comically suggestive to the no holds barred "Brazil".

The unfortunate thing is that because of anarchy laws we cannot do a darned thing about it!

Otherwise we would?

I doubt it Wink

TG, I second your motion. Plain daylight highway robbery. And it's global.
 
Graham - about bloody time. I know you are overworked and underfed, no news, but I seriously think you should have done this a long time ago. Mostly because I tried several prototypes I have hanging around with your amps, and they showed promising results.
 
Especially the shunt editions ... (hint, hint!)
 
Anyway, better late than never, as the saying goes. I wish you much luck with it, Graham, and will lay down good money it will only improve your products and image.
