Re: Kolster Brandes RV 10 (Crown)
The LOP valve PL81 does look to be working hard. In darkness a slight blue glow can be seen in side the electrode structure. The anode plates do look to almost be red but it difficult to see from the heater glow. I have never looked at one of these close up in a working set before so I don't really know what normal operation looks like. I appreciate the circuit has a lot of energy. Certainly the line whistle suggests this. I will take a picture later.
I could not get any arc from the anode cap of the U26, or from the connector either.
