Phasor II Mu-tron mutron phaser 2

[newperson]

Hi,
I would like to see about the transistors out in the Mutron phasor.  They are:
2sc1852 = ?
2sc828 = ?
2sa666 = ?

Are there standard transistors I can replace them with?

I honestly can't see anything in there that absolutely demands the power-supply specs shown.  Feel free to use a pair of 3-pin 12v regulators, and if you absolutely hunger for those specific supply voltages, you can always trim 12v back to what is shown....but I don't see anything in the design that requires it.

For the light-source driver, the schematic shows that a 2N4401 can be used.  This is a pretty common part, available in most industrial suppliers, large and small.

Thank you Mark for the reply.  I will look into that.
