Keep in mind you have no way to know an "ebay pull" is really a "pull"
from another unit vs. someone simply offering the same "dubious
provenance" part while stating it was a "pull".

I.e., the ebay seller could simply be offering the same dubious part,
with the "value added service" of applying a small bit of solder to the
pins to make it look "used" before shipping it to you.

Hi folks,
I've received the transistors this morning, however, I am unsure if I will install them. I was supposed to receive a 1M30D-060 but received a suspicious 1MB30D-060. The datasheet from Fuji mention a 1MB30-060 and a 1MBH30D-060 but there's nothing about a 1MB30D-060 which makes me wonder if I've received bootlegs. (Fast forward 2
hours later) I have inspected inspected both transistor more closely and I'll be damned if these thing haven't been sanded down and re-lazer etched. You can clearly see the grain : /

Ordering most any simiconductor off ebay from another country is very
chancy. I know several in the local ham club that bought from over seas
and the simiconductors were faulty in one way or another. I bought some
20 watt RF transistors and they would only make about half the poewr
they should have. Reordered from a reliable source in the US and the
new ones worked like they were supose to.
