The Crown DC300, introduced in 1967, helped define the era of modern power amplifiers [5] In 1959, Crown began making standalone tube power amplifiers. By 1963, solid state electronics development allowed Crown to produce a more robust tape recorder, and in 1964, their first solid state power amplifier: the low-profile SA 20-20. [2]
This can be exceeded for a short time, as long as the average is not exceeded over the anode's thermal time constant (typically 0.1 sec). In Class-C applications, the amplifier output power delivered to the load may be higher than the device dissipation; One or more manufacturer-proprietary letters denoting the construction variant
Generally speaking, solid-state power amplifiers contain four main components: input, output, amplification stage and power supply. [8] MOSFET transistors and other modern solid-state devices have replaced vacuum tubes in most electronic devices, but tubes are still used in some high-power transmitters (see Valve RF amplifier). Although ...

HH Electronics is a British amplifier manufacturer that was founded in 1968 by Mike Harrison, Malcolm Green and Graham Lowes in Harston near Cambridge, England, where its first solid state TPA and MA range of studio quality amplifiers were designed and manufactured. These amplifiers were used by many recording and broadcasting studios ...

The receiver is filtered by a 22 pole crystal filter with switchable extra 8 and 6 pole narrow band CW filters, a 14 pole SSB filter and a separate 14 pole CW filter. The RF circuit is based on a – manually or automatically – microprocessor controlled PIN diode attenuator with 2 bipolar power transistors used as a high level RF amplifier in the receive mode and as a double RF output pre ...
