Exactly ! That is why I am Buying 500 pcs Smiles. However; I did post somewhere a generic circuit using a pair of PNP low noise hygain transistors in parralel.

Will try it eventually with 2 x 2sc1730L. If I run into issues.

Will learn how to use "Spice" to model the circuit and give me the correct values.

Interestingly I have used 2sc2999. Works in a couple of Radios. Most the original is better. If I remember 2sc1675.

Luckily only have about 20 2sc2999. Nickel each. No biggy.

The Shotkys work though quite well in my Trc457 and several other radios.

Allright back to this 7.8MHz filter !
