This document contains circuit diagrams for the power supply, preamplifier, and protection/display circuits of a PWP 6000 audio amplifier. The power supply circuit includes transformers, rectifiers, and voltage regulators to produce positive and negative DC voltages for the two amplifier channels. The preamplifier circuit uses operational amplifiers to receive and amplify low-level audio signals for the two channels. The protection/display circuit monitors temperatures, voltages and currents, and includes components for controlling relay switches, LED displays and overcurrent/overtemperature indicators.

Todos os resistores são
de 1/4W e todos os ca-
pacitores eletrolíticos
são de 25V, exceto
aqueles com indicação.
O circuito do power do
canal B é idêntico ao do
canal A.

Caso seja usado o transistor
2SA 1837 no lugar do 2SA
1006 e 2SC 4793 no lugar do
2SC2336, substituir os capa-
citores de 39pF x 500V por
150pF x 500V.
