I bought from Little Diode around 10 years ago, a variety of RF transistors similar to and including 2N3866 with the specific intention of comparing them for suitability in LF/HF active antennas. However all the devices they supplied looked to have been rebranded from the same generic stock, I'd had some experience of this in the past but it still took a LOT of effort before I finally got past the evasive responses and they admitted this was true, which of course made any comparison pretty pointless. They didn't refer to them as "generic", can't remember what expression they did use now in their initial responses but remember it wasn't something I'd come across before, but there were certainly no indications at the point of sale that these weren't original manufacturer's branded stock. Such rebranding and subterfuge was common amongst some at least of the aftermarket electronic valve suppliers in the late 1960s, a bog standard device going in one door could come out another as the ruggedised version, for example, and much more expensive, and it would seem similar practices lived on. I wouldn't touch them again with the proverbial barge pole, although I have to accept others may have had better experience.

I might be worth asking eBay vendor LittleDiode, they are the eBay shop for LittleDiode Components ...

It's a three terminal device that looks like two silicon diodes in parallel. It was making the meter read about 10.1V with a 10V input. Luckily it was temperature sensitive and was easy to find with freeze mist. Removal caused a shorted input to be about 2.5 microvolts high and a little noisy. I've not been able to find this device on the internet but thought that someone here might have seen this thing before.
