Default Re: Sorry for the double post.

There's a dealer for Neutrik on Lamington Road in Mumbai. I'm heading down that side today, let's see if I can pull out contact info for you and whether they'll ship to the NE.

He seems to have a good collection, and prices aren't that bad. Gold plated RCA plugs are about 50 each, balanced 1/4s are about 70 bucks, and unbalanced 1/4s are 65 or so. He revers me since the day I walked into his shop and bought 4 grand worth of plugs and wire in one go to rig up my recording rig.

I saw speakons on a poster on his wall, dunno if he's got stock? I'll check!

Tarun,
I have made two boards using SOICs, 1206 and 0805 sized SMD packages through this guy by giving him laser prints. All traces were 0.016" (that makes it 16 mil? Sorry, I always forget) I have a 1200 dpi laser whose density setting I set to max. I'm only worried about some tiny white spots that appear in large dark areas such as ground planes and really wide traces (done in Eagle using polygons). Anyway, the DSP board requires finer pitch than an SOIC, so I'm keeping my fingers crossed.

At work, I have a Tektronix Phaser (also 1200 dpi) whose output is a much more rich, dark black. I've sent one PCB using a print from the Phaser, I've yet to get it back. No, it didn't use SMDs.

I'll try and attach an image of my SOIC boards. They came out very well indeed. Perhaps their being glass epoxy helped the traces stick to the board better.

Ashwin,
Tubes? TUBES??? Hmm... will check it out. Texonic is on Mandi Veerapa lane (same as the one where Universal is, perpendicular to SP rd). It's inside a building, so it may not be readily seen. They have a Gainta catalog from which you can pick enclosures. Or you can see their website which I found with some difficulty (google doesn't find it ) And yes, I will try to get to know the CNC operators. Just hope I don't get fired

Vivek,
Did you get an idea of other stuff Corrson has? Do they have stuff from Peerless Denmark too? I was interested in spending my hard earned money on a long-throw sub, which Vifa apparently doesn't have. Anyone care to correct me on this?

At the risk of recommending a supplier who you allege fleeces, you can look for the part number 3400958 on www.rsindia.com. Alternately, drill down from "Electrical" -> "Audio/Video" -> "Loudspeaker Connectors." And guess what? Unlike the others, RS will deliver by mail order. They even have people who can take a phone call and give you prices of any RS Stock Number item over the phone, instantly, and discuss delivery schedules, payment modes, etc. It's possible that part of the "fleecing" goes into running their superb encyclopaedic Website and providing this customer service?

Yes, with a 1200 dpi laser printer, you can do a little more. Yes, 0.016" is 16 milli-inches, i.e. 16mil. I saw the PCB layouts you've done. They look lovely. But with layouts like this, I agree a laser printer should be adequate quite often. 16mil is quite easy to handle, specially if you have a 1200dpi printer and a fresh toner cartridge. Your PCB layouts are actually quite straightforward, without tracks passing too close to other pads/tracks, etc. If you needed to take a track through two SMD pins, you'd have had a tough time, I suspect.

And if a laser printout on tracing sheet does not do the job, get a bromide made as Angshu does. That bromide is much less expensive than a Gerber photoplot; it needs much less expensive equipment to make it, I guess. Visha in Bombay makes very serviceable bromides, with very sharp edges and good contrast, from laser printouts on ordinary white paper. I've got those bromides made many times. Those bromides will be more than good enough to make the screens from, I think. The only problem with them may be that they may not last as long as the Gerber photoplots do, with repeated usage. But then, getting fresh bromides made is not very expensive.

I gave a laser printout on tracing sheet to Mr.Subramaniam three days ago. He called yesterday saying that he's tried making screens from that sheet, and it's not coming out well.. too much light is passing through the black areas on my printout. I knew my printer's toner was heading for end-of-life, so I put in a new toner and took a fresh set of printouts, and sent them to him today. Let's see what he says tomorrow. And these are very undemanding PCBs, with wide component spacing, 24mil or wider tracks, and all discrete components, on a single-sided PCB. (It's the PCB for a Randy Slone power amp.)

So, I guess the printer's black saturation and ink transfer all play a part, not just resolution. But in any case, Angshu's approach is an excellent low-cost via-media. You take a printout on paper and get a bromide made... it's always worked for me. The bromide chemical is hugely high-contrast, so even a not-so-rich-black printout translates to a very rich black bromide.

Are these the Elektor circuits, BTW? They'd published a lot of digital audio stuff, including an ADC, a DAC, a sampling rate converter, etc, at one point.

I just called Balaji Hertz just now. The new printouts have been used for making the silk screens, and they've turned out perfectly adequate. They're going ahead with the making of my PCBs.
Good.

Can you please let us know the name, physical location, and address of this shop? Would help. Is it on the ground floor bang opposite the police station, and does he have a lot of cable sections displayed in his showcases? If yes, that's the chap with whom I've seen Neutrik RCA plugs too. I think it's in the same building which houses Visha on the 1st floor.

Default About Neutrik Speakons

Sangram,

You know its so very nice of you to do that. If you can find the connectors for me,(NL4MP-UC, NL4FC) do let me know how much they will cost. Sheesh! had I known all this time that they were available in India I would'nt have imported them. I'm crossing my fingers hoping they would be available(after u check them out) and of the same kind- Not like the Peerless problem in the other thread.

I hope you know how they look like. In case u don't This is how they look!!

Patrick

Tarun,

Don't get me wrong, but as a Farnell distributor in North East India, I know what value is all about. Unlike Farnell however RS components do indeed less for certain items aside from the low MOQ advantage that RS offers. Although most of these Incs provide us with really good components from reputed brands, contributing to the 'low noise factor' in our DIY gear, for some components, I really don't see much difference in quality. Take for example this very expensive RS long nose plier owed by a friend of mine here that he had claimed to have bought from Delhi for Rs.400+. I mean I was surprised to see rust all over it a tell tale sign that my friend had not used it for a couple of years. I was more surprised when a few hundred pieces of the same pliers he had bought landed up in my small shop which I had ordered from a Chinese firm. The built looks like a cloned copy of the RS plier. Either the Chinese firm stole the molds from RS or the other way round... whatever but I realised that the unsold Chinese pliers that were in my shop haven't gathered rust yet. Its over a year now. I have no other way to explain this phenomenon and therefore had to infer that this must be the same molds with different metal castings.

Anyway that was exemplary of RS. Imagine what they could do with other things in their inventory.
By the way did I tell you that I sell these nice Chinese pliers (cloned from RS) for Rs.50 only a pair. Now thats a Rs.350 + difference we pay extra for using RS search engines and a nice encyclopaedia. If you think thats money well spent... I have no qualms whatsoever. Like yousaid earlier its just subjectivity all over and who knows I can just as well be wrong!!!

Patrick
