well with my on going hv issue with this set i do have a question. with the set on hv present at anode crt plug off should there be any voltage at any of the crt pins. i checked with a dvom to ground and have no voltage at all except at the focus pin which was 7 volts , would this sound right ? and the hv with the anode wire off the crt is 19kv just at the wire. anode wire back on, crt plug off i was lucky to get 22 kv, thats it, picture scene changes and will dip right down to 19 kv or less. i didnt try another crt yet but was looking around for something concrete here that may give me an idea the crt is finished maybe due to gas. i read an article online about crts and what was said about getters is that a bright shiney mirror like getter is good no air or gas. however what also was said was that a white of course means it took on air but the last was a getter that is coal black no mirror shine at all indicates gas in the tube. has anyone heard of this coal black getter meaning a gassy crt ?
