Folks:

Thanks for the feedback! Because my stop in Chennai is the first of a few, I won't be looking for finished products or anything fragile. Roushon's point is well-taken -- I'm primarily interested in stuff that is relatively light-weight and locally crafted (or at least very competitively priced). Digikey, Mouser, Sonic Craft and Parts Connexion, which are my usual sources, all offer good to high-quality parts at a decent price, and I don't buy so much that it would make sense to purchase large quantities of stock items; they would most likely never get used. So I'm not exactly sure what I'm looking for; perhaps it's the hunt alone that I'm after.

Samuel, thanks as well for the invitation to Bangalore! As it turns out, one of my meetings will very likely occur in your city. However, I'll be on a tight schedule and under the watchful eye of some people I work with, and hence must -- with no small amount of regret -- respectfully decline your kind offer.

Once my schedule is better defined I'll post another note and again solicit your advice. Thank you, very much, for the quick and enthusiastic responses!

Regards,
Scott

I still have to start the project. Good u woke me up. Presently I am using Leach Amp for my main speakers and this RMI FC100 was thought of for the Subwoofer, which I don't have presently.

I will come back soon with the details, as I am now(currently bored) sweating for some DIY.

Hey Try him.

I bought couple of Transformer from him.
Price was reasonable, and Quality too was good enough. ( I saw him doing loading tests for my transformer.)

Its Saumi Enterprises.

Default Panasonic FM capacitors

I am looking for Panasonic FM electrolytic capacitor.
Internationally online it is available but before that does
anyone know if I can get such genuine capacitor in some
physical/online shop in India? I need quite a lot of them in
many different values.

Thanks and regards
Roushon.

Rubycons are a common sight in Indian shops, only if they can do.

Thanks Gajanan. Actually planning to mod my Marantz cd5003 player. So looking for very good quality caps but not blackgate type, of course, for obvious reason. Following suggestions from a thread in this forum.

Roushon.

Edit: May be some of us will ask you to bring some parts from the US ...it is like when I was going to Greece for a conference I asked the same question in this forum to people from Greece....

Enjoy your stay in Chennai....

This is something Ive been wondering about! For some reason your logic tho very reasonable does not apply. Parts are much cheaper in India than in the US, even tho they are from US companies. I have bought parts from local retailers in the US (Houston) (who cater to service centers) as well as Digikey, Mouser etc. A good eg. is the common microcontrollers from Microchip. They are sold here (Bangalore) at a fraction of the Digikey price, and they are quite genuine, as far as I can tell.

The problem is that the local parts shops are living in the 90s. Very few "modern" parts are available. Thus if you want a 74HC series logic chip you can readily get it for peanuts but if you are looking for an FPGA, you will get blank stares. Any op-amp more esoteric that the LM358 will be difficult to find.

Another major problem is the prevalence of spurious parts, esp. power transistors/MOSFETS. Honest dealers will frankly ask if if you want the genuine or the "duplicate". Others will palm off the spurious part and rip you off. I just bought a heap of MJ15003/4 pairs which look very dubious. Fingers crossed.

Retail prices for small quantities of components are quite high in the US, because of rentals, wages, etc. Same applies to most of the mail-order and online vendors. However, there are very good deals to be had from surplus and small EBay vendors of specialty components.

The bulk of the market is fast-moving commodity stuff. They cannot risk locking up capital in fast-depreciating specialty items. Hence, you'll find TTL, PICs, commodity opamps, etc. Quite easily. Incidentally, you do get FPGAs, mostly surplus Spartan-2 and -3 from the telecom bust hangover, but the Chinese have mostly mopped up the excess stock, so the great deals don't exist any more.

Commodity stuff is generally genuine - there's no money in faking a TL074 or a BEL 2N3055. The risk is specialty parts like an MJ21195 or similar.

If they're aluminium case, they're fake.

If they're steel-case, made in Mexico and feel heavier than a 2n3055, I'd give it 50:50 odds that they're genuine.

If in doubt, cut open the case of one of each with a Dremel. If the die size looks to be the same as 2n3055, then it's a re-badged 2n3055 or MJ15015. If it's larger, it's mostly genuine.

The safest TO3s to buy are BEL - they're too cheap to counterfeit. 2n3773/2n6609 at Rs.40 each will be mostly genuine. For this reason, they're also a bit scarce.

Highly unlikely, though you do get FC, FK, FJ and FL occasionally. I have no idea why FM is scarce - it's heavily over-rated. It has magnetic leads like its other F-series brethren, and sounds harsh in many audio bypass applications. FJ is better, and costs a fraction of an FM. IMHO, several commodity Elnas, including RE3, RJ4, RJH, RJJ, RSE, RSH sound way better in most audio bypass applications, but YMMV.

There are superb Panasonics like Pureism PXL and Master Ta-keh, but mostly unobtainum even internationally.

However, Nichicon Muse FG, KG and KZ are widely available and give good results. The sub-miniature Muse SW is almost as good as a BLack Gate PK, at a fraction of the cost.
