Notes

Tube tester with manual voltage adjustment, 10 valve holders, one 5mA instrument, with added functions for Ohmmeter and AC/DC Voltmeter. Model 777 is a basic emmision tester wich conects every tube as diode, merit of emmision is done in AC conditions with positioning of load reostat to apropriate value.
Main transformer is autotransforming type thus there is no insulation between testing circuit and the power line, so there is a posibility that the chassis may become "hot". The use of a mains separating transformer is highly recomended and could be installed inside of the tester.

This tube testing section is virtually identical to Model 450.
