At your risk. Lethal voltage present.
Five rectangular holes have been created by a jewelers saw for housing five 2 x 9V batteries for a Vb of 90 volts.
All 5 Bulgin battery holders will be at the back of the diecast aluminum box. Then the output transformers then each DL94 for each channel and then the step up input transformer for each electron tube.
In the front will be a Bulgin holder for 2 AA batteries for the direct heated cathode voltahe Va, and a battery holder of AA size for the -6V Vc bias.
This amplifier is using no resistors or capacitors, like the original Harold Arnold 20's patent of the use of thermionic currents...
