Think twice before you throw away old consumer electronics. Often they contain a huge amount of nice components to add to your spare part stock.
This week I saved a printed circuit board from an old Samsung colour TV (over 10 years old with CRT). Some components to retrieve from this board:
Of course there is a VHF/UHF tuner. Nice part to make your own panorama receiver for example.
Furthermore lots of resistors also big ones (> 5 Watts).
About 10 chokes (coils), 4 xtals, voltage regulators (7805, 7809, 7812, 7915), lots of
capacitors in all kind of values (from 20 pF ... 220nF). electrolytic capacitors, heat sinks, on-off switch, variable resistors, Japanese transistors (common use and special transistors for video purposes).
I will not desolder the specialized video ICs and hi voltage transformer (which has collected lots of dust). I am sure I will never use these.
Who said our hobby is expensive ? All you need is there free for use :-) And the internet is your best friend when you want the details from an unknown object.
