Putting part numbers into google is helpful but, it wont help you on a test. So here is the answer to four of the most common things that you will end up seeing (most likely). Diodes: One arrow pointing into a small bar Zener diodes: One ar...

What are your application? Transistors don't have to have low noise. It depends where they are. Normally only the input transistors are important. BC546, 547 548 549 550 556 557 558 559 560 etc are normal and OK in most situations. BD135 1...

Mostly because of their cost but also because silicon transistor have faster switching properties and are far more resistant to damage by heat. Silicon transistor also have a much wider operating band.

Your main problem is likely to be the higher frequency response of modern transistors introducing unwanted instability. This amp is not compensated for these. The 2SD119 has a modest Ft of a few hundred kilohertz, as do older 3055s, but mor...

Transistors have three leads which must be connected the correct way round. Please take care with this because a wrongly connected transistor may be damaged instantly when you switch on. Some types may be identified differently

They should be germanium if you want to get the classic 60's/70's "soft" distortion. Silicon has been used, and many people like the harsher clipping, but it is a different sound. Among germanium transistors, many type numbers (se...
