Can enybody help me to find the substitute for PT6068 and PT6067 power BJT ?
I've search the web but withowt any resoult. The mentionet BJT's are the power devices from an power amp from KÖRTING dated 1983. From the first look I think that they are darlington transistors (TO247 casing) because on the PCB are only TO92 case (...)

102r means 1K to me.
Then look on this webpage the line "2N3904 Equivalent transistors" (after the transistor characteristics list)
The follwing page will give 58 entries
And I guess BC546 and 2N2222 could do the same job as already pointed out.

Most microcontrollers should be able to drive an optocoupler with an external transistor but with only a limited current. I would suggest replacing the 2sk941 with any general purpose MOSFET such as 2N7002. You could use the 2N2222 but with any bipolar you need to add a series base resistor.

This is the schematic I am working on.
Is there any substitute for the inductor which has a coil and a ferrite slug in between?
Can I use a fixed inductor for that? And if yes, what value?
And also is there any substitute for 2N3563 transistor?

If you install an AT motherboard with both ATX and AT
power supply connections, in combination with an ATX
power supply, in an AT enclosure, this circuit will save you
from also having to install an additional pushbutton switch.
