Hey guys, the other day my TI-89 fell off my shelf and onto the tubes in my Little Dot. The tubes were clearly knocked part-ways out of the sockets, so I hurriedly turned the amp off. I waited about an hour before messing with it, and I reseated the tubes and turned it on. Everything seemed to be working fine. But just in case, I wanted to put in some 6JIs into it in place of the 408As to make sure nothing was amiss. So I took them out and put in the 6JIs. I turn the tube amp on and everything seems okay, until I notice the tubes are glowing really bright...10 seconds in and all of the sudden, smoke starts coming out of the headphone jack. I rush to turn in off, wondering what the problem was. I pull out the tubes, which after 15 seconds are quite warm to the touch, which is very unusual. I open the bottom and I am greeted with a puff of smoke. Turns out in my haste to change the tubes, I neglected to flip the switch for the different tubes. So now I don't know what to do. I don't think it is safe to turn it back on with any tubes in it at all. If it was smoking, some damage was done for sure. But how can I tell what kind of repairs it needs? I don't wanna send it back to David, because the shipping costs both ways, plus any repair costs could probably buy me a similar amp. Any suggestions? I don't know how I forgot to change the settings, but I did and now I don't know a safe way to test it. Thanks!
