OK. When I finally got home at 9:30 tonight, there was a big box sitting outside my front door, left there by UPS. Apparently my dear wife had not even peeked outside all day, or at least since late afternoon. As you may have already guessed, my prodigal TT101 was inside said box. I just now unpacked it, and guess what. The SOB is working fine here in my kitchen. I am not going to breathe on it.
Apparently the TT101 is a lot more complex than the TT81, thanks to the unique reverse servo mechanism in the TT101. Thus I have no doubt that the TT81 would be less problematic. But nooooooo; I had to have the "best". Serves me right.
Should I run and borrow that Timeline from my neighbor, while the TT101 is working right? The tach is set in the mode where it counts repeatedly up from zero to set speed, over and over again. I prefer it in steady state mode, where it reads the speed with no re-cycling, but am I going to flip the switch that changes the mode? Not on your life. That may have something to do with this fragile triumph.
