WJ-9040 Receiving Systems

The WJ-9040 receiving system carries the design philosophy of the WJ-8617/8618 receivers to the next logical step, a modular rack mount design. The factory "receiver systems" came in a variety of configurations. they are becoming increasingly common on the surplus market.

The four systemsbelow are just a small sample of the numerous configurations that can exist. The original WJ-9040 system catalog came with black system racks and stickers of components, so cutomers could piece together their own configurations.
