Thanks 399 for the above information. Ok let me find out if I got this right.

Target Transistor is 2N5770.

Monograms Oh Lordy. No simple way to figure Ft. Ft = 900 at 100MHZ

I am totaly Lost. Alright. After looking at 4 different manufacturers data sheets got this.

1800 MHZ

so HFE = 1800/27 = 66.6 So if I got it right.

It seems this Transistor looks like a good substitution for the original Nec 1730L.

Honestly. It really is hit or miss on FleaBay.

Would rather pay .30 cents with shipping than a Dollar plus each on FleaBay and then get disapointed.

Actually-Ripped off.
