description: The work is devoted to questions arising during the modernization process of preamplifier tract in the SRV 5 transmitter. A scheme of a narrowband pre-amplification path on the Russian element base was developed and it was shown that the load power for such a scheme P=30 W. Due to the fact that the narrowband circuit requires setting the tract to a certain frequency, a broadband path was developed, in which this tuning is not required, but more power is needed. An interesting possibility of forming pulses due to the recharge of the input capacitance of the lamp is considered, which allows a sharp decrease in power.
