[Lowfer] W1VD modified Amrad whip tested (matching jfets notneeded?)

[Clint Turner]

Don't forget Palomar Engineers - they don't have a minimum order.

***

In addition to the J310, another interesting FET is the Philips BF863:  
At audio frequencies, anyway, it's quieter than the J310.  The downside 
is that it's SMD only and its maximum voltage is a bit lower than the J310.
