? saba: Neutralization
I am trying to uderstand the neutralization adjustment for this radio (Freiburg 9). My understanding of the instructions is as follows:
Set VHF generator and receiver tuning to 93 MHz.
Switch off anode voltage of the previous stage (unsolder wire from solder-plug 2).
Increase input voltage to approx. 0.5 mV
Adjust C 204 to minimum for neutralization.
Re-solder the anode voltage from the previous step (wire to solder-plug 2)
Repeat steps 1 to 3 for precise adjustment.
I canot see "solder plug 2" on the schematic. Does this mean disconnect the anode/plate of the first EC92, even though this is Pin1?
Your advice would be appreciated.
