Hi,

Can I replace two 2N3904 transistors in TH VCO core to one 2SC1583?

Many thanks.

I think there will be no problem, I do the opposite (when I need one 2sc1583 I repaced with 2 handmatched 2n3904)
Just watch the pinout.

I dont know if this would be a problem:
Reading from the datasheet, the hfe from the 2sc1583 is 250-800, the hfe from the 2n3904 is 50-150 aprox.
