Got a Beltron, looks like it restored my RCA B&W TV CRT

Just received the Beltron 8080A CRT restorer, and after figuring out which adapter the 21CEP4 required, (I didn't get the chart saying which adapter goes with witch CRT) hooked it up. The green meter didn't read any cathode current. Had to figure out if the Beltron was even working. Between the cathode and G1 was about 120VAC, and using a diode and a 100K resistor I could make the green meter show about 0.5ma. Okay, do position 1, jack up the heater voltage to 10V, I see about 0.05ma. On to the cleaning and short removal, but no shorts found. Now to restoration, Turn heater voltage to 10V, and in about 10 seconds the blue restore indicators start flashing. The instructions didn't say to expect this, at least I didn't see it. Pulled the adapter cable out of the socket after a few seconds before it might blow up the CRT... But I go back to position 1 to do a test, and the CRT now produces the 0.85ma. And connect the TV set CRT socket to the CRT, and the CRT looks normal now, and it looks steady for the last hour or so of TV watching. It's likely too early to do a just yet.
