I left my Q on all night last night... Thats one thing I like about batteries. When the heater batteries go dead - then its off. I use AA rechargeables. They dont last a whole night on... Those tubes will probably outlive us anyway... no worries. We'll be in an old fucks home and the tubes in the Q will still be good. - dont know about you, but - thats where I'll be - looking forward to it too....
