let me check with myself then....i may have a couple of them, all sealed, never used. bought from primeabgb itself. would post the update here later today.
sorry for being late. and sorry to disappoint you now - have got cathode tubes, but they are WHITE in colour, and have got a couple of bubble-tubes too, but they are RED in colour.
try in some local shops. may be you could find some other brands'.
