[NLRS] [Mw] 1296 Amplifier Transistors

[Charlie Betz]

W6PQL states on his website that the transistors in his kits are harvested 
from Spectrian amp modules.  He may very well sell the transistors 
seperately.  I was able to buy the kits minus the transistors from him for a 
pretty good price.  I emailed and asked if I could buy them that way and the 
response was "no problem".

By the way, I purchased brand new MRF286 transistors from Jerry, W7QX for 
$20/ea. I bought a dozen and I think it cost me $6 for shipping.  These are 
the solder style transistors, not the flange type.  KB9PJL is in the process 
of machining the heat spreaders.  Hopefully we will be ready to start 
assembling some amps soon.

Charlie, N0AKC
