This power amplifier kit takes 40 - 50 volts, a 3 Amp transformer (31-0-31 or 33-0-33V) Such as: 640-483 Two IN5401 didoes and a 3300uF 50V cap are recommended as rectifier section.
Power supply kits QK114 and QK186 would also be suitable.
Being an OTL circuit, the speaker is protected if the output transistor is shorted.
12V output for Tone Control
Output devices are C1061 power transistors.
The output has a capacitor on it for short circuit protection.
Heatsinks are included with the kit
PCB Dimensions: 2 circuit boards measuring 4 6/8 x 1 3/4" each
Heatsink dimensions: 4 heatsinks measuring 21/4 x 3/4 x 13/8" each
