After the transmitter has to be made with the smallest possible wiring, the transmitter must be tuned. The tuning is done with the variable capacitors and with a milliamometer connected to the 807 rise. The milliamerometers on the rise of each lamp should be Tuning to indicate the minimum indication while the milliamerometers of any lamp have the maximum indication.
The transmitter configuration is made from the final stage and in particular from its rise by means of a modulation transformer that is part of the final step of an acoustic amplifier. The power of the modulator for correct configuration must be 30W.
