Instead of quick reply press go advanced at the end of the page, there you will see an attachment button which opens a dialog to attach a picture, file etc.
If you want to add a link to an image there is a add image icon at the menu over the message, this exists in both quick reply and advanced.
From what I can tell the 2sa1015 is only rated at 40v, so wouldnt withstand the volatge shown on your schematic.
At lower voltages I'd use a bc559 for the 2sa1015, and a bc549 for the other, but be warned these devices wont stand 230vdc.
Voltage rating is one thing, power rating and providing suitable heat sinks another. According to the circuit dimensioning, Q1 and Q4 can be loaded with up to 2 W, depending on the function generator setting. Did you take this into consideration? If there's no reasonable purpose of operating the amplifier at this rather high power level, you may want to reassign some resistor values. Complementary transistors with sufficient voltage rating (and also power capability, if actually needed) can be found e.g. in the Onsemi portfolio.
Also Q4 misses a base-emitter resistor to absorb Q3 leakage currents.
The selection of maximum rated Voltage and maximum rated current, is not enough to ensure proper wattage.
We must consider the Safe Operating Area (SOA) wich is defined in grafical format at datasheets.
That power is also restricted by switchin frequency.
