I always use Cricklewood Electronics in London. Never had a problem with them.

Do a search on google and you'll find them.

I'd recommend sticking to a worldwide supplier such as Farnell, Digikey or Mouser. They should all ship to Portugal.

isc is inchange semiconductor.. a chinese company well known for making fake Sanken transistors.

The best way to test 7815 is to feed at least at least 18V into it, and see if a stable 15V comes out. Put some small load on the output e.g a 47 ohm 1W resistor for a current load of ~32mA. Similar for 7915. See their datasheets for the relevant info.

Not from eBay - this is pretty much the number one source for getting fake parts.

The only place I can recommend you would get genuine high quality parts from is the big companies like Mouser, Digikey, RS and Farnell. They all get their stocks direct from the manufacturers.

I wouldnt be surprised if I found some NOS Motorolas here. Want some?

By the way: MJE2955T and MJE3055T will also be up to the job.
Originals is available "everywhere".
Also I can manage to get hold on some TIP2955/TIP2955 from ST. Around $5,-/each.

The FST239/240 have not been made in over 20 years - i will be very very surprised if you find originals.
Stick with ZTX653/753
