The original tubes are not really that bad, a little weaker than the NOS tubes I bought. What would cause this and has anyone had these issues before? Thanks
You may want to check the color burst crystal. I've never had one fail but I hear they can go bad. Also, with that being a pc board chassis, loose grounds and bad connections should be suspected. There also should be an adjustment to allow you to achieve accurate flesh tones with the tint control at mid position.
