It would be a funny rack.
No mains supply.
No power transformer radiating electromagnetic noise.
Just input, output transformers.
XLRs for, input output.
Switchable in parallel Pleiades L filters for proximity, or RL filters for Fletcher - Munson, voice effort curve compensation. R can be variable, the potentiometer on the front panel.
The Pleiades bias resistor can be variable, again pot on the front panel.
The heater voltage can be variable on the front panel.
Very important to include a fuse holder, holding a suitable fuse for safety.
The power supply component can be an elegant Bulgin AA, or C battery holder. The battery can be front loaded on the front panel.
Normally Rag (Pleiades bias resitor) is 6MΩ, Cc is 22nF. A Nuvistor 7586 can also be used.
The baby rack is a small rack, a 9in rack?
