Default Re: Baird T5 restoration project.

Testing the power supply unit. The 16mfd reservoir capacitor and the 24mfd main smoothing capacitor were found to be useless so for the time being two 8 + 8 mfd capacitors will be used until the correct components can be found.

Under no load and with only 150VAC supplied from the variac the smoothed HT voltage is 300V. Later today the vision and sound receivers will be connected to the power supply.
