2SA1455K/2SC3722K SMD vs 2SA970/2SC2240 - diyAudio一坐上去就黏住了吧...??? I don't know where you get the less good linearity from. Cob for the Rohm parts even seems to be a bit lower (~3.4 pF vs. 4.0 pF at -10 V for the PNPs), which correlates with the somewhat higher fT. Feel free to derive Early voltages from Ie(Vce) for your...
