    Mike Matthews Freedom Amp from the 1970’s. This is the two speaker amp. It has two power transformers in parallel and a S37005 transistor mounted on the power supply filter capacitor. I am looking for a schematic or connection diagram for the transistor /capacitor assembly. Thanks

    That’s not a transistor, it’s a full wave rectifier. Standard power supply configuration.

    It has the bridge rectifier but it also has a S37005 transistor mounted on the power supply filter capacitor.

    Likely a house-numbered 2N3005 power transistor.

    It’s suppose to cross to a 2n3055. The cap was not clamped down and all the wires were broken off. Need a schematic or connection diagram.
