FINAL ENGINEERING SUMMARY
The two preamp gain stages utilize a specially-selected 12AX7A. The tone controls incorporate ICs, and
the power amp is designed with extremely high quality bi-polar devices. Each type of device was chosen for
its performance and reliability in the application used. The front panel and chassis of the 350x are com-
prised of aluminum, because of its superior electrical and thermal characteristics and light weight. All pri-
mary electrical components are U.L. approved, and SWR uses Beldon Cable for all shielded wire. All units
are assembled by hand and individually soundtested in the U.S.A. at our factory in Southern California.
