germanium transistors

AF114 germanium transistors and related ones like the AF115 through AF117 were quite popular during the 1960s, but they quickly developed a reputation for failure. This is due to what should have made ...

Tubes Versus Solid-State Audio Amps—The Last Word (Or “House Of Fire,” Part 2)

Fig 1. This basic source-follower circuit is the kind of amplifier you would find in an electric bass guitar amplifier. R6 provides the feedback. On the other hand, low-distortion applications require ...
