Description

The 490B is intended for the checking and rejuvenating of the cathode ray tubes (CRT) for both color and black and white television sets and monitors. With this instrument you will be able to find and repair leakage or shorts by measuring the RGB current of cathodes. You will also be able to plot voltage/current features and to rejuvenate each cathode separately.
