I have been going through some Amplifone tubes recently and came across one I wanted to share.
The deflection and HV are 100% on this machine. The yoke and focus rings are properly installed and the monitor is degaussed and converged good enough for testing.
I attribute the above anomalies to color phosphor burn. I suspect a specific color of the phosphor has been burned away in these areas making them void of this color. I have never seen this before with an Amplifone so I wanted some other input on this diagnosis.
Thank you.
