@Mooly @katiyar @JMFahey @Dibya @NareshBrd & everyone....
We won the battle!!.... On my request DAC stopped selling that batch. Now only BEL 2n3055 is there. Here is the link & screen shot. Definitely it is a good news for indian diy community. Thnks to DAC & to everyone who joined me in this thread. Say no to counterfeits!

Obviously. ..DAC is the official distributor of Dayton audio & the only online seller of High end drivers like Mark Audio etc in India.Well done. That sounds like a good result
Well done Mr Bhowmick, That's precisely my intention was on the subject. One should not be taken for for a ride for getting cheated like this. It is good to hear that atleast they have accepted that the component they were selling was not up to the mark and have stopped selling them.
CDIL must also be apprised regarding the entire episode.
I still do not understand how DAC is still selling BEL 2N3055 so cheap?.
The thing is that most American companies will cut off their agents if they are accused of malpractice, they are very strict.
Indian companies, and some Americans, might say 'go ahead and sue'...
But in every business, reputation is important, and the fact that they tried to blame the previous owners, was at least an evasive response...the value of the parts was less than 5 US$, most would exchange or credit for bad parts.
That was the really bad thing they did, and as it is I found their site a little expensive.
Also, they are selling mono amp kits saying those are 1875 or 2030, the populated PCB is less than the price of the genuine chip, and the maker's logo is not on the photos.
In India, the biggest electronic component markets are Delhi, Mumbai and Bangalore, and with the advent of on line trade, many merchants have faced problems, as customers find better variety and prices.

Due to lack of confidence on others, i placed a new order at RS comp for some ST Tip3055(to-247). I believe tip3055 is good enough for JLH Class-A although no Ft spec in datasheet 🙁

Why would one expect TIP3055 to be any different from any modern expitaxial 2N3055, except for the package?
I always remember the guy in the stores at college back in the 80's. I remember asking for a TIP3055 and the reply was 'Ah, the indestructible transistor'. I've never forgotten that.
HAPPY you could solve that issue, congratulations. 🙂 🙂 🙂We won the battle!!.... On my request DAC stopped selling that batch. Now only BEL 2n3055 is there. Here is the link & screen shot.

Thanks but that is not enough.
In this thread, for 1 post which mentions both currencies side by side, there´s 10 which do not.
FWIW I do not even mention local prices in Argentine Pesos in an International forum, go figure, not even quoting the exchange rate; living in a Metric Country usually post Imperial dimensions side by side, when needed °C besides Fahrenheit, AWG besides wire diameter in mm, etc.
Basic Forum courtesy.
PS: you know I AM a user of Indian made 2N3055, over a thousand of them (if not 2000) in much abused Guitar/Bass/PA amps, for years used excellent quality USHA/UR 2N3055H ones, preferring them over ON or ST, go figure.
Not only that, never could measure them side by side or look at the die but I guess the die or process is different, there is a reason they are still called TIP3055 and not 2N3055, worst case 2N3055P (lastic).
I have tried to use them many times, and in the exact same circuit, same speaker load, TIPs vaporized while 2N held their own.
2 extra examples on TIP series apparent poor SOAR:
TIP35/36 have impressive specs (100V Vce, 25A Ic) yet they are destroyed easily
Yet lower spec TIP142/147 , 10A Ic tops, are robust as H*ll and have replaced 2N3055 as the de facto standard for MI amplifiers, an unforgiving market.
And they are housed in TO218/247 case!!!!!!!
There are beasts housed in same, including some MJL****
Some day I´ll do some inductive discharge tests (the hardest to handle for a transistor) at different levels until I reach destruction and compare, but so far my empirical experience is as written above.
Thanks, it´s very kind of you.
NOW we can compare at once 🙂
As in: I used to to pay 67 US cents each, straight from distributor (not an over the counter or small online purchase so a Commercial/Industrial price) , by the 100s, in original marked from Factory ST cardboard cases, transistors protected in Styrofoam shelves inside.
International prices have risen (US dollar is worth less) but I guess they are still below the 1U$ mark ... in those quantities of course.
My distributors (and others like him) do not sell to public, and buy straight from US distributor.
OR from a large wholesaler such as ARROW or AVNET
They get Kemet caps, SanCon electrolytics, Fairchild, Vishay, etc. straight from the source, it was difficult for me to "get their attention", they only care about "big fish".
Oh well.
