content: Hi All,I have a Sennheiser EMP2015-B Soundfield Audio Amplifier, Wireless Microphone and headset microphone available for sale. Offers accepted send via Private message. I live in Warnbro Western Australia, can deliver anywhere although fairly heavy unit so expect fairly high delivery charges.I used to deal in the Soundfield market and did well for Sennheiser in a lot of areas until the typical Australian Government placed certain restriction that could not allow me to operate any more in Telephone and Audio industry in my current structure. I am now selling anything that I can't use.This is a brand new unit and never used, it is the last of the stock I used to carry a long time ago. I powered up the unit complete and tested all functions are working but wasn't expecting anything but as it has never been used.Few photos of the actual unit. I am sorry for the quantity of photo, I have resealed the box forgot the photos of the units out of its plastic bag. There is a product brochure -http://www.directproaudio.com/images/products/Soundfield.pdfTotal Actual Weight - > 4kg

content: Update: both units sold.I have two HP E3610A DC power supplies for sale on eBay. These are 230VAC only, although they work fine with the SG 240VAC mains.Quick specs: single output, CV/CC operation, volt/current adjustable, two ranges: 0-8Vdc, 0-3A / 0-15Vdc, 0-2A.Full specs on the Agilent site:http://www.home.agilent.com/en/pd-838240-pn-E3610A/30w-power-supply-8v-3a-or-15v-2a?cc=SG&lc=engItems are in Singapore, shipping to Oz, NZ, UK only.

The flat price unit has better cosmetics, though it is missing its serial number label. Date codes on various components show 1994. The auction unit has visible signs of age; case part yellowing, fading. Both units have the usual nicks / scratches from use.I have cleaned both units, and performed the service manual adjustment procedure. I have not replaced any parts, though I cannot guarantee that all parts are original since I purchased them used. That said, everything looks original. I have used them for about two years. The voltage load regulation and load transient response has been verified to meet factory specs.14 days inspection period; buyer pays return postage for a refund. The usual caveats - item must be returned in the condition it was received, the test seal must be intact.Thanks!

timestamp: July 11, 2013, 12:31:40 pm
content: Dear tronixstuff,At the time I set up my fax no. it was free to the fax recipient.The Faxplus service provider (http://faxplus.com.au/) made its profit from the 1900 number.It was a fax to e-mail gateway service. In other words a fax sent to that 1900 number ended up as an e-mail addressed to me with the fax as a PDF attachment.I'm not big on fax in this day and age, but I wanted to provide this to my customers who still want to use a fax machine.The Faxplus service recently went belly up (See:http://faxplus.com.au/), so I really sould remove that fax no. from my web site till the problem sorts itself out.There is another alternative that costs a little more, but you get a real (02) for Sydney local no.Fax to Email Servicehttp://www.crazydomains.com.au/fax-to-email/At $3.50 a month its quite good value for a (02),(03),etc fax no.The alternative is a dedicated Telstra line connected to a real fax machine which was not the cost effective way forward.

Forum section: electronics / general

author: TopLoser
author_rank: Unknown
timestamp: July 03, 2013, 01:38:45 pm
content: Hi,I've recently unboxed an Agilent DSO5054A 500MHz 4 channel 4GS/s scope which was bought about 5 years ago and never used. I think the original purchase price was about £8,000 plus VAT! It's complete with all manuals, CD's and 4x500MHz Agilent probes.It all seems to work perfectly and obviously looks like new because it's never been used. Only problem is that channel 4 exhibits a lot of vertical instability and noise, it displays a trace but it jumps all over (about 2 screen divisions of noise). It looks like the signal ground isn't connected, only it occurs even with the input grounded. Channels 1,2 and 3 are fine.If anybody fancies a really high spec Agilent 3 channel 500MHz scope then this is for you! You might even find it's a really simple fix.It is a lovely scope, data sheet here:http://cp.literature.agilent.com/litweb/pdf/5989-6110EN.pdfI'll ship anywhere at cost, scope is in England.

content: Quote from: apelly on July 01, 2013, 03:26:42 pmThats a good idea! Also check local universities. They usually have surplus departments (though sometimes you have to contact the engineering department to find out).Also, looking at ebay, you can still find some that ship to NZ. Even with shipping being more than the cost of the PSU, its still cheaper than the one you listed.I have seen at least one Power Designs Precision and one HP Precision power supply that came in under the price of that one. I'm not sure of your amp volt requirements so i can't quite advise.

content: Quote from: Galaxyrise on June 24, 2013, 03:14:31 pmCurrent sources can supply desired current independent of voltage. Voltage across a current source is determined by the devices it is connected to (opposite to a normal power supply where current drawn is usually determined by the devices). Power supply has zero output impedance whereas a current source has infinite output impedance. (I am talking about ideal sources of courses). Keithely 225 I believe a 10 Teraohm resistor.Current sources cannot be used as normal bench power supply, however it can come very handy for experiments calibration, also I guess some diode testing as well.

They're 2 channels 0-32V 0-5A each channel, the usual CV, CC, tracking/independt modes.http://uk.farnell.com/tenma/72-8700/power-supply-bench-2-x-32v-5a/dp/1836058?Ntt=tenma+72-8700Only problem is that channel 2 on each supply is unregulated. Channel 1 seems fine. They're linear designs (and heavy) and don't use any fancy SMT or custom components, they should be easy to fix. From my experience the build quality of Tenma stuff is erm 'questionable' at best, there's a very good chance it's just crappy soldering somewhere.List price in the UK is about £200 each, anybody fancy a punt at £50 each or £75 the pair? £10 shipping because they're heavy.Update: both sold.

If you sell the drives and ram, I'd run some diagnostics on them and post a screenshot with the S/Nhttps://www1.hgst.com/hdd/support/download.htmThe Drive Fitness Test from Hitachi (formerly IBM's drive division) I've used for 10+ years and it has always done a great job. It will do more extensive tests on IBM and Hitachi drives, but it does a great job on other branded drives as well, often finding faults that the motherboard's onboard diags can't.For the ram, I recommend Memtest86+That way you can say with some confidence that the parts are good and perhaps get a slightly better price.

Maybe that IDE interface is desirable ... but, IAC, I assumed a HDD would be the LEAST desirable component of legacy PCs--I'm thinking factory/industry use, not hobbyists, or folks like Dave, makin' educational vids four YT:You noted Hitachi drives ... yeah, they seem to be the most reliable of any brand I've used. (I have over a dozen now, mostly 1TB or 2TB). Hitachi merged with WD two yrs ago, but WD was already up to most Hitachi "standards" even beforehand. MTFB has been gotten pretty good with the latest, while warranty time has been reduced.

content: There seems to be interest in using wire wrap for making circuits. This is a panel I acquired from a piece of test equipment a long time ago, not haven't used it so might be of interest.Made by Cambion. Consists of a row of 4 sockets each of 10+10 pins on 0.3" spacing. There are 20 plus 20 of these rows. The rows have a pin spacing of 0.2" side to side. Therefore you can directly insert DIL components on a 0.2", 0.3", 0.5" and 0.8" row spacing.The pins still have the wire wrap on them. There are also a number of headers. There is a power buss arrangement on the pin side as well.Look at the photos.Overall size of the aluminium frame is 11.1/2" by 10.1/2", weight is 2kg.Price is £25, 25GBP, postage in the UK is about £12, 12GBP, postage outside the UK will not be cheap!

This part of the industry doesn't appear to have really embraced the web yet.At full retail, their price is competitive (after currency conversion), but you still have to add GST of course. That burns a bit. Such is the nature of a usage tax.To be fair, Emona called me (I think the same day) when I sent them an email, but I missed the call and haven't gotten around to calling back.
