Hi everyone,
Just joined the forum this afternoon and I am having problem troubleshooting a high B+ Voltage on the following Wells Gardner monitor
Sticker on the Horz. Transistor: WGM-1972-U2BS05G
054A7200-001
Google 054A7200-001 and got a schematic 19K7201 that is identical.
Primary side of T3 – 164V
Secondary side of T3 – across C101 187V and drops to around 167V (schematic shows 126V)
C57 – 100uF / 160V reading 0Uf was replaced.
I can see a glow at the corners of the monitor and hear the HV when it is powered up but there is no filament light or raster.
Any assistance will be greatly appreciated.
Thank you
