2N3904

MMBT3904 (2N3904 in SOT-23 case), PZT3904 (2N3904 in SOT-223 case), 2N2369A, 2N2369, 2N2222, BC547C, BC547B, BC547A, BC547

10_turns_on_8mm

Make from insulated copper wire of 0.5mm^2...1mm^2 crosssection. Can be replaced with 1uH factory-made coil. However must be rated on at least the current the power source gives when shorted.

LM7805

LM78M05, L78M05, uA78M05, MA7805, 7805

BPW43

SFH203, SFH2030 (for SFH203 and 2030, not the P and F suffixes!), BPV10 without F suffix (slightly worse), OP905 (3mm package, requires drilling smaller hole, degraded performace may occur depending on lens quality), Hamamatsu S6436 (expect degraded performance)

BF908

KF907, BF988, BF998 (BF988 in SMD), BF982, BF992 (BF982 in SMD), BF961, BF960

NE592_DIL14

TL592 DIL 14, uA733 DIL14 (NE592 equivalent), SA592 DIL 14, SE592 DIL 14, LM592 DIL 14, uA592 DIL 14, NTE927D (DIL 14), NTE927 (can use only if you can understand the NE592 and NTE927 datasheets to reassign the pins (14->10) and reorient the chip properly in relation to signal travel direction), uA733 TO-5-10 (metal can with 10 pins) . Do not use anything in plastic 8-pin or 10-pin package -- problems with stability! With TL592, connect pins 3 and 12 to ground.

BAT46

BAT42, BAT43, BAT 48, BAT 47. Not BAT 49!

75 Ohm resistor

68 Ohm resistor

1.5uH coil

1uH coil
