I have a Gauntlet Legends Showcase with an extremely dim monitor. I decided to test it with a Sencore cr7000 to check the tube, but information about it seems to be difficult to come by. I need to figure out the Bias voltage, but I can't find it.
TUBE: A90AGW14X
CHASSIS: Neotec NT-35E
NECK: Neotec NT-3501
I have been able to decode most of the information by using
http://tubular.atomized.org/sencore.html#s/A90AGW14X
http://tubular.atomized.org/#s/A90AGW14X
And then cross referencing the CR71 socket type with a known monitor that is both in the Sencore manual and the BK Precision lookup list located at https://bkpmedia.s3.amazonaws.com/downloads/pdf/CRT_Setup_Chart.pdf
This gives me the Universal Adapter(UA) Pinout
FIL: 6.3V
BIAS: ?????
F1: 10 F2: 11
K: R-9, G-7, B-12
G1: 6 G2: 8
The tubular site says the bias is 'D', but no explanation of what that is. I have also found other monitors that say 'D' and they do not have a consistent Bias Voltage.
Also, i'm not confident with the G2 Test Voltage selection. "Video1" or "Video2".
I would appreciate any information along with the source material for that info. The Manual is not available for the NT-3501 on http://www.arcade-museum.com/manuals/manuals_monitors.php
