Signal Center, Pentagon Building, Washington DC. Final tank condensers and antenna coupling condensers of the press wireless 40-kw transmitter. This is a straight r.f. amplifier with a frequency rage from 5.3-21.0 megacycles, utilizing a class "C" push pull cross neutralized circuit. The plate tank circuit of this stage consists of a tapped inductance and two variable tuning condensers technically ganged and are arranged so they can be operated in a series of parallel as determined by the operating frequency. The two 233 type tubes are located directly behind the final tank turning condensers. Here the M/Sgt. hold a set of shorting bars which adjusts the amount of inductance on the take coil.
