[ICOM] 2SC1972 drivers?

[Robert Chudek - K0RC]

Be VERY careful regarding sourcing replacement drivers off eBay (or anywhere 
else for that matter)!!!

I just learned about this (first hand, I saw the photos and official 
documentation) in January...

One of our local repair facilities recently ordered several hundred dollars 
worth of parts, including these hard-to-find drivers. The shipment was 
confiscated by US Customs as they were claimed to be counterfeit parts. As a 
matter of fact, they turned out to NOT even be RF parts, rather devices that 
the original identification was removed and a new (desired) part number was 
stamped in its place.

Upon close examination you could see the quality of the replacement 
identification was poor (fuzzy, not sharp and clean like an original part). 
Placing an unknown part into your circuit might lead to even more damage 
than the original driver component failure.

I don't have the sellers name, but the parts were being "made" and shipped 
from the Far East.
