Substitute Components

[rinnyrig]

Hi all, I am looking at building this power supply from the link following,
https://www.electronics-lab.com/projects/power/003/index.html
the problem is the transistor 2N2219 for there seems to be none of them here in Australia. Can anyone suggest a substitute that may be available here.

Regards
Geoff

Hi rinnyrig,

2219 ?
thats to drive the 3055, yes ?

just looks like a small npn to me,
nothing special,
gain is pretty immaterial,
40 volt max,
half amp max,

i think anything close would do,
try to pick one with the same pin-outs ....

Best of luck with it, John

Any basic transistor would work, Like BC548 or pn100. You can get both of these at www.jaycar.com.au.

or you could try www.dse.com they got a few shops in brisbane.
