4.2. E.H.T Check
Item / preparation
1. Receive an RF signal, window or crosshatch pattern.
2. Set the Brightness and Contrast to minimum (0 Beam)
3. Connect the High Voltage Voltmeter to the CRT ANODE
CAP.
4. The set should be switched to AV (no input) contrast and
brightness minimum.
Adjustment procedure
1. Check the EHT voltage is (31.4 1.0) kV.
2. Switch from AV mode to TV.
3. With the Brightness and the contrast controls MAX, check
that the high voltage does not drop more than 3.0 kV from
the above measurement with R.F. signal.
