Restoring my AC-4
Scheme of the AC-4
So that you can see the new values of the DRAKE AC-4 components, I have attached an electrical diagram of the complete restoration of my AC-4 version 5.0 for Spain.
In the primary winding I have put 5 voltage inputs: 215, 220, 225, 230, 235 VAC in order to choose the voltage that you have in the radio room.
Also in the electrical diagram you have the different new values of the different components to get the best performance and maximum reliability from the DRAKE T-4XC transmitter.
The direct current voltages (VDC) are taken with the transmitter running and transmitting from 160 to 180 W on the RF output (this source can also be used with the T-4X, T-4XA and T-4XB models).
