Nice bundle for anyone needing that kind of stuff.

New output devices and a much easier to service respin on the board. Now you can unsolder the devices and remove the board, then replace them and feed the leads in after assembly.

Someone suggested a charity ebay auction, sounds like a plan.

So Dave, what made you reconsider your opinion on the Korad PSU? This quick video sounded rather positive (calling it a "winner"). I was under the impression that you didn't want anything to do with it anymore after Korad kept coming up with excuses/delays over and over again.

Just curious ...

Charles tested the new one, and it seems to perform as expected (hence the word "winner"), see his video. As it did when I tested it until it failed, which they seem to have now, finally, fixed. If it didn't fail when I tested it, it would have gotten a good review.
Yes, we are not happy with Korad about their response and communication,  and I have no interest in reviewing it myself again as result. But that opinion doesn't change the fact that the unit, as it stands, seems to be good bang-per-buck at that price point. As always, YMMV.

Actually I considered bying the Korad, even tho it blew up on your bench, Dave. It goes for ~100€ at the Polish distributor www.hotair.pl , which makes it even more attractive (if you don't mind waiving support), imo. The only reason I didn't buy it yet is because I bought some other really cheap "lab" PSUs. I might do a limited review of them soon.

BTW, I tweeted that I will be getting one of these in few days:

Will be interesting to see what it's like.

Exactly!

Good quality PSU's (e.g. Agilent) are very expensive, so often you have to go for the best bang-per-buck you can find.

They do occasionally come up on Ebay, though. That's how I've ended up with 3x HP 6632B's on my bench

Does TrioSmartCal sell the new version already? and do they do worldwide shipping?

Pretty rare here in Oz unfortunately to get good HP supplies, and when they do come up, go for a pretty penny.

It's on their website and are available.
They probably can ship, ask them, but it will likely cost a LOT.

Oh, that certainly looks like an interesseting power supply. Maybe I'll wait for that review before buying myself a power supply.

If it's not a secret, how much have you paid on average for each one?

[AndyC_772]

They all came from the same guy in Finland, and ended up between about £150-£170 each including shipping:

He had a whole bunch to sell - I'm guessing a factory closed down, perhaps - and advertised them in batches over the course of the year. Sadly I've not seen any more recently, though it might be worth dropping him a note to ask if there are any more likely to become available. They all worked fine and were accurately calibrated.

I guess it's the shipping cost that's the killer. The 6632B is *heavy*.

Hi Dave.

Is there any label with version number on the PSU? Can we see a photo of it or see it on your next video?? I wonder about buying one.

Michal

[george graves]

Ask the seller - most will know their stock.

I think I'm going to buy two of these this week.  It's 1/6 of the price of a HP unit, and I love the interface.

[Michal]

Thanks for your advice but I don't know which production version is the new one. So I'm pretty sure that seller won't give me any help.

[TRIO_Smartcal]

All ours are modified stock. Plus all our stock has been tested by us for short circuit test and a ramp up to full load test.

We are not the cheapest resellers of these in the world and I'm well aware of that. Our volume in the Aussie market is not high so our cost to get them here by air is not the lowest either and this shows up in the sales price. We don't import stuff by sea as the risk is too great.

Included in our price is a 2 year warranty and Dave knows where we live!!

The only place we ship to now outside Australia is New Zealand.

I can look at the costs to ship to Europe. We use DHL or TNT.  I'll post  the cost to the London area on here as a guide when our logistics manager returns from Christmas leave on the 7th Jan.

[SeanB]

Probably in the region of $ 70 per 5kg parcel, as that is a pretty common cost for international courier, with a 10kg limit normally. Triple that for a "Hazardous" cargo. ie one with lithium primary or secondary cells, compressed or flammable gas or any flammable liquid or anything containing either listed chemicals or strong acids or bases.

Michal,

I think your bet bet is buying from somewhere you trust. Yes, it might not be the cheapest place but you know you will backup incase something gones wrong, and with this supplies short history, well worth it IMHO. I ordered one from Trio just before Xmas, and I'm a happy first time customer. Seeing how they reponded to the issue tells me everything I need to know.

Cheers,

Wayne.

I ordered mine from Trio yesterday.
