VT1, VT3, VT4 transistors may be BC847 or similar (i.e. BC547B, etc.), VT2 BC857 (i. e. BC557B, etc.). Fast silicon diodes of any type will do, for example 1N4148 LL4148 in MiniMELF case. LP2950 is replaceable with LM2951 appropriate resistors, 78L05 the worst choice due to it's own high current consumption. It fail work some cases. Use an external power source. Cable RRxD ...
