Topband: Using a 40673 in a KD9SV preamp

[sire@iinet.net.au (Steve Ireland)]

G'day all,

Since I posted the note about using a 40673 instead of a 3SK88 in the KD9SV
premamplifier, I have had several e-mails inquiring about what currently
commercially available MOSFETs could be used in place of the 40673/3SK88.

Back in QST November 1991, it was noted that the ECG222 and NTE222 were a
direct replacement for the 40673, when it was discontinued by RCA in 1990.
I am not sure if these are still readily available, but they would be worth
making inquiries about.

Vy 73,
