I have a set of 8300s. In 1992 when the station went on the air, the bought a set of them and couldn't even get them to work. So, TFT sent them another set. That set wouldn't work either. When I say they wouldn't work, I mean across the bench from each other. So, eventually they sent a loaner that did work, and the station kept them. Fast foward to around 2007. I discovered oddities with the transmitter including when I closed the door on the back of the rack or disturbed the unit in any way, it would drop off the air. Banging around would restore it to being back on the air. It turns out there was a very crappy piston capacitor that wore out because they sent it around as a loner unit. Normally piston caps aren't that prone to failing. I guess TFT used the cheapest parts they could find. Since then it's ran OK. I've also had extperience with TFT EAS units. Frankly, most of their stuff is minimal. It runs, but not great. I'd go with Moseley or even the new BW Broadcast analog STL system. It's based on their FM tuner DSP technology. That's a very far cry from TFT.
