Hi Ed,
   I knew about the 2N3866 and 2N5109 disappearing so I bought a bunch of 2N3866 while they were still in stock. Same transistor die only with a lower Ft of 800MHz instead of 1500 MHz.
 I have used them for years in a similar preamp circuit. I can send you one or a few at $3.00 each which is what I paid. And a little postage. 
You are correct, don't buy the Chinese ones as the ones I received were so slow they must have been audio transistors.

I remember about a year ago a discussion not to buy the 2n5109 transistors from E-Bay sellers . Some searching shows the 2n5109 has been discontinued for many years . So is anyone that's been saving one for many years willing to part with it ? I'm using it in a W7IUV pre-amp .

Thanks Ed N5DG
