content: Hi all,I am looking for the Vantek DSP3305P USB programmable power supply, and I can't find any. So far, two vendors have given me refunds because they cannot source them.As I am tired of looking, I am offering $100 via Paypal to anyone who can supply me with a source for two DSP3305P power supply units. I figure if this community can't find them, nobody can.Rules:NON-OVERSHOOT models only! Overshoot models (Yori, Quakko, Protek) NOT allowed.Must have the USB port and be supplied with cable and software. No non-USB models!Equivalent models that use the Vantek software are OK.My understanding is the 3A model never comes with USB, but if you can find one 3A is fine.No gouging. Total price should be around $200 or less. I will look at higher prices but can't say I'll bite. If I do, you'll get the bounty.Source must be able to ship to Canada.NO UPS GROUND shipping. I do not care to pay UPS the $100 I will owe you!Payment when I actually get the units in my grubby little hands. As noted, two sales have already fallen through.$50 bounty for one unit, $100 bounty for two units.UPDATES: I have already tried:MIB Instruments- not USB (physically verified by MIB)Kibuck Electronics- purchased, but he could not deliver.Precisegauge.com- purchased, but he could not deliver.Goodluckbuy- not USB (according to photos)Goodlucksell- not USB (I asked)Results so far:Glyby: Not USB. Plus it's marked Yori, which has the overshoot issue.Glyby #2: Not USB - marked as USB/software not included.Aumiton: outside desired price band, but have inquired anyway. UPDATE: They claim it is in stock, has USB, 110V/220V compatible. Over my budget.Alibaba (Baku): Linked product is minimum purchase 10 units, cannot confirm USB is present. Can sell 1 pc, but photos show USB is missing.EEVblog post: Looked through here but cannot find a purchasable sourceMastechPowerSupply: Sells Quakko, which has the overshoot issue. I have bought from him before and asked him anyway, but got no reply.eBuy17: Cannot confirm USB connectivity. Anyone speak Chinese so I can check?EEVblog: Can't purchase from here, no links to workable stores.Protek: Per the review link above, the Protek and Quakko models both have the overshoot issue.Taobao: (page in Chinese) Closest so far.Please, no suggestions for alternative brands models. As far as I can tell, the Vantek software is the only suite that meets my needs.I will entertain offers from owners who want to sell theirs. If you have one, make me an offer. If you can buy them new and re-sell them to me for a fat profit, more power to you.Post here or email me at titam2@shaw.ca. Thanks in advance for all replies.Titamp.s. - yes, I am serious. $100.

content: Thanks for the help, Simon.I assumed that my email address would be available in my profile, as it is on some forums. Not an entirely unreasonable thought, as there is a "Allow members to email me" option in the registration process. My email is titam2@shaw.ca.[Edit: oh, look, my email IS in my profile. Go figure.]As for your Google search:mib_instruments cannot get the unit any more, I checked. Their auction says they can, but when they actually looked at the received unit it did not have the USB port.goodluckbuy unit does not seem to be USB.mib_instruments link #2.glyby unit is not USB.glyby link #2.The other first-page results are mostly shill blogs and other non-stores.So, you see, I have actually tried. In fact, I have spent the last several weeks looking on eBay (USA, Canada, UK, Germany, etc.) and scouring Google.I went ahead and purchased one from precisegauge.com, but they refunded after they found they could no longer source it. I then purchased one from Kibuck Electronics, but it arrived at their shop broken. They very nicely found this out before shipping, but informed me they could not be sure of getting a working unit anytime soon, so another refund.I came here looking for some help in the hope that someone knew of a source. Also in case anyone else out there was interested in one in the future, this information might prove useful to them as well. Excuse me for not being clear enough in my first post.The good news is - if I am really a flaming idiot, then someone out there stands to make a very easy $100 off of me. Good for them!So, more info - I have talked with and/or purchased from these sellers, but they were not able to help:MIB Electronics (eBay / webstore)Precisegauge.com (webstore)Kibuck Electronics (eBay / webstore)Goodluckbuy (webstore)Goodlucksell (eBay)TorqueRanger: Thank you for helping! Unfortunately, MIB tells me they can't actually get the USB model any more. They bought one, but when they examined it it was found to lack the USB port. I should have mentioned this in my earlier post, that was my fault. Sorry for the trouble.I should also note that if anyone can point me to a kit or sch/BOM combo to convert the non-USB Vantek to a USB, I will pay them $50 as well.I am willing to go ahead and design a simple PCB to do the conversion, but I don't want to have to do all the design work myself. (Something like what these guys did with the Atten supply:http://www.ebay.ca/itm/180928497419?ssPageName=STRK:MESINDXX:IT&_trksid=p3984.m1436.l2649.)Thanks,Titam

content: I'm interested, provided it meets the criteria in post #1 above.Be aware that I have had three suppliers physically check their units, and they have all come back to say that they are not, in fact, USB-equipped - even though they are supposed to be. Some photos of the rear of the unit(s) in question would certainly help my confidence.

No pictures that I can provide you with. You can find the seller from Taobao.com if you search "caltek 3305p". It's all in Chinese though.

content: Quote from: titam on November 14, 2012, 04:25:03 amAs you should be able to see from the Taobao website, the basic unit is 410 CNY (Chinese Yuan). USB and software is an additional 120 CNY. I'm not sure about shipping from where they are to where I am (Hong Kong), but I reckon the total per unit will not exceed US$100. That hasn't included shipping From Hong Kong to Canada though. I'm not going to mark up the price any more than your bounty plus rounding up a few bucks. I can also verify and send you pictures before I send it out to you. I have an eBay store myself so if worst comes to worst I'll just suck it up and offer it for sale there.

content: Quote from: titam on November 14, 2012, 05:34:53 amOK, I've inquired. Total price including shipping to Canada via Speedpost (http://www.speedpost.hk/speedpost/index.jsf, estimated 2-8 day delivery, trackable online) will be around $170 for one unit or $300 for 2. The seller says it might weight up to 5kg per unit after all the packaging so the cost is a little higher than my original guessitmate. Price still subjects to change depending on the actual shipping costs (might be lower). Let me know if you want to proceed.

content: Just a quick update on this: The 2 Caltek units were sourced, sent, received and tested by the OP. Shipping took a little less than a week. But while I did personally run some basic tests on the units and made sure they worked before I shipped them out, one of the units turned out to be not fully functionalAnd as such I'm asking the OP to only send me half the bounty for the service. I'm hoping that the half functional unit will still be put to good use or maybe be repaired at some point (the problem seems to be fixable). I want to thank the OP for putting the trust in me for this whole deal, though I feel truly sorry that he only gets 1.5 units in the end

content: Update: One of the units worked but only up to 8.9V. A brief look inside did not reveal anything obviously wrong. It may be repairable, I just don't have the time.On the positive side, the units have no discernible overshoot and the software is better than I expected. I think they're going to be very useful. Even a 9V 5A supply has significant uses.iloveelectronics was very helpful and did more than he needed to for the deal, so consider this a positive feedback for him and his eBay store. Communication was great and I'm sure that he did a lot of testing of the units before sending them out. The transatlantic trip was probably just too much for the one unit. I wouldn't hesitate to buy more if I have the need. Thanks a bunch!!!
