The a power supply of 80V, it becomes necessary to put a series capacitor in between the output stage and the speaker in order to block the DC supply from entering the speaker and allowing only the amplified 100 watt music power. The 2N3055 power stage at the output should be mounted on large heat sinks to ensure that this crucial stage is able to dissipate adequately and function with optimal efficiency. The input stage is created by configuring a couple of current drivers transistor stages responsible for triggering the pairs of power BJTs positioned at the output stage. Few suppliers still have the older RCA 2N3055H transistors.Simply by incorporating just four transistors in the quasi-complementary configuration this 2N3055 simple power amplifier circuit can deliver a good 100 watts of power over an attached 4 ohms loud speaker, and the entire design can be built at a really low cost (to be precise it would cost you only 1/2$ per transistor).Īs exhibited in the above diagram you won't find no costly or obsolete hard to find components in this amplifier circuit, except the power supply transformer and possibly the 4 ohm loud speaker.
Repair shop personnel report 2N3055H transistors perform better in vintage equipment. Note: Genuine RCA 2N3055HOM/2N3055H Power Transistors have a reduced bandwidth as compared to the new currently manufactured 2N3055 replacements. RCA - 2N3055HOM is a High Reliability Version "Hometaxial Selected version" of the old standard which often works as compared to earlier versions "E" (Epitaxial). Max Current: 15 Amp collector, 7 Amp base.Īpplication: Designed for general purpose switching and amplifier applications. Then only the base layer had to be etched free for contacting. They were manufactured by simultaneously inversely doping a wafer with a base doping on both sides, thus generating the emitter and collector layers. The first transistors were called hometaxial, and this model is certainly one of them. Over time, RCA changed the structure of the 2N3055 transistors. RCA - 2N3055HOM / 2N3055H Transistor, NPN Silicon.
