Ito contribution ko,pakidelete na lng kung meron na.
REGULATOR IC
7809=7805,7806,7812

ito naman COMMONLY USE AS SUBSTITuTE Horizontal Out x'sistor
D2499
D1878
D1424

diode substitution
RU2=RM25
R2KS=R2M

capacitor substitution 47uf/16v
=33uf/20v
=35uf/28v
(it should be high voltage rating than the original value in case of you cant find the original value.and it should be low microfarad than the original value)

i have one question: could replace the resistor of 1watt from 1/2 watt but the same value?

how come 7809 regulator can be substitute to other regulators? pede lagyan mo ng drop out resistors XD,

dun sa tanong mo..pede naman pero syempre depende sa application mo, you have to compute your system's rating baka di kayanin.. mas ok ng masmataas ang wattage kesa mababa lalo na kung alanganin ka =)
