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 ;-) -- Gordon JC Pearce MM0YEQ gordon...@gjcp.net ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author.

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. 73 Trevor M5AKA ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author.

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 .

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. 73, Ben VK2FBRB On Tue, Sep 6, 2011 at 2:20 PM, David 4X1DG 4x...@iarc.org wrote: Domenico, It can help our community, if you could provide some info on the vendor. was it an eBay vendor? ___ Sent via AMSAT-BB@amsat.org.
