What follows is the field test for the CR70:

Set the CR70 controls to the following,  F1 to 1, F2 to 2, K to 3, G1 to 4, G2 to 5 ,gun select to R/B&W ,CRT select to Video, function to Remove G1 short.

Hook a DC Voltmeter ground lead to G1 lead of universal adaptor and the positive lead of the DVM to the K lead of universal adaptor.
When the rejuve button is pressed the DVM should read greater then 350 volts DC.(CR 101,102,103,104 and C101,102,103,104,105)

Set the function switch to the rejuve position and re-press the rejuve button and check again for greater than 350 volts DC.

Set function to Auto Restore and set external DVM to DC current. Press the rejuve button and the CR70 should cycle three times. When on the current should read between 80 and 120 milliamps.(TR101and L101 and IC105,106 or cold solder on restore swirch board.)

Set function switch to manual 1 restore.Press the rejuve button and the external DVM should read between 80 and 120 milliamps with no cycling.

Set function switch to manual 2 restore. Press the rejuve button and the external DVM should read greater than 150 milliamps.

Set function switch to cutoff. Set external DVM to DC volts. You should be able to read the BIAS voltages (-68, -52, -36, and -20).(CR106)

Move the positive lead of the DVM to the G2 lead of the universal adaptor. When the cutoff control is adjusted look for a voltage swing of 20 to 400 Volts DC.(R211 and CR101-104 and C101-105 and CR203,204,205,206,207,208)

Move the DVM ground lead to the F1 lead of the universal adaptor and the positive lead of the DVM to the F2 lead . You should be able to read the filiment voltage on the DVM. It will be dependant upon where the filiment volts settings are set to.Note: if your CR70 has two power transformers on the bottom panel the filament voltages will be AC volts.(IC 201 and TR203,204,205)
