Subject: [Amps] Source for 2SC5305D transistors
> Greetings to all,
>
> About a year ago, I sent out a couple of posts about modifying the
> Ameritorn QSK-5 PC, QSK board, to operate with a higher reverse bias, thus
> allowing operation into a higher SWR. In this mod I substituted 2SC5305D's
> for the original switching transistors.
>
> I ordered 50 of these devices from a source, one of several, on
> eBay. I have now used all 50 from the original order and have four boards
> (needing 16 transistors) on my desk, at the present time, for upgrading.
> Unfortunately, my source for the 2SC5305D's has dried up and I have been
> unable to locate them, except from a couple of rip-off artist, for $12 to
> $16 each.

> If anyone happens to have some of these transistors (must be in a
