 The left capacitor is encapsulated in original conditions while the right 
 capacitor has
 been decapsulated.

This is old, old stuff.  The backstory to is is that it's an *American* device, 
not Chinese, and it was done that way to disguise fitting a more modern 
capacitor into a vintage amplifier.

I can't remember why they went with 2200μF instead of 6800μF - possibly the guy 
that did it felt that 2200μF was adequate.  It was over a decade ago when I 
first saw it along with the writeup ;-)

Stuffing capacitors is a standard technique in the restoration of old radios. 

If anyone had the time to waste they'd probably find the original of that 
picture on one of the many US websites dealing with restoration work.

The picture was circulated around 2007/8 in an email attempting to smear 
components manufactured in China.

Actually is very difficult to find some type of RF transistor like 2SC1969 ,
2SC1307 , etc .
Sometimes they take TIP41 , repaint e sell like original one .The appearance
is very similar .

Unfortunately, counterfeit parts are flooding the market, especially parts 
in limited supply. Some components may be painted and stamped with the 
choice of a difficult to obtain component.

It can help our community, if you could provide some info on the vendor.
was it an eBay vendor?

That pic has been floating around the Internet for several years - it's not
just a single vendor (and shonks aren't endemic to China).
Check out http://www.google.com/search?q=fake+capacitorstbm=isch for many
horror stories.
