Method of restoration of kinescopes by shooting from its surface
Waste slag

The method of reconstructing the kinescope is based on the shooting of the spent particles from the surface of the cathode. With this method of recovery, the lifespan of a kinescope can be extended from one day to one year. It is best to restore the kinescope 61LK4TS, 61LK1,2B, 50LK1,2B.

RECONCILIATION TECHNIQUE

It is necessary to apply the glow voltage to the tube by the following procedure:

1. a) apply to the kinescope incandescent 6,3V and allow it to run for 15 minutes.
B) apply 8V for 2 minutes.
C) apply 11V for 2 seconds.
2. Feed the 6.3V and press the SA2 button, thereby disconnecting the condenser
To the modulator cathode. This operation should be repeated 1-2 times.
Then connect the wires "to the cathode" and "to the modulator" to the other gun and
Repeat step 2. Change the glow, this should not be.

DETAILS

Transponder T1 - any power transformer can be used from
TV. Suitable even for the old lamp.
The voltages on the windings of the transformer:
7-8 - 6,3V
6-8-8V
5-8 - 11V
3-4 - the voltage obtained after unloading should be 150-200V
The diode VD1 - KD226 (it is possible
Put the diode bridge)
Condenser C1 - 10μF 450V
Switch SA2 - type P2K without latch
Switches SA3.1, SA3.2, SA3.3 - three-section switch type
P2K with a clamp (i.e. it is three P2K connected together by one clutch.
Resistor R1 - type MLT 20 Ohm 2W
When the SA3.1 button is pressed, the
Be 6.3V, when pressing SA3.2 - 8V, SA3.3 - 11V

Attention!
When working with the device, do not forget the safety rules!
