[QUOTE="fredeb, post: 871840, member: 13623"] Good for me to also learn about this - thanks ! I remember reading a particular ( can't remember which one ) American valve datasheet , where the "*"-a suffix meant the valve had a longer filament warm-up time . I'm not sure whether the purpose of this was to stop the flash , or to prevent a power spike . Perhaps someone in the know can enlighten us . [/QUOTE]
