Circuit Box - Electronic Valve Amplifier, Trevor Pearcey, 1960s Object Reg. No: ST 045078

Valve amplifier circuit used by Trevor Pearcey, an Australian computing pioneer who designed CSIRAC, Australia's first computer. This amplifier circuit was possibly used later in Pearcey's career; it is difficult to say if it was used with CSIRAC but it is of the same vintage.

The item lacks the two vacuum tubes required and a power supply.
Rectangular metal box with plugs on the top. Inside are a Ducon condenser, electrolytic capacitor and other electronic components. The valve sockets are designed for 8 and 9 pin valves
