FL- I can't shed any light on the TFL designation either. But, since nothing else on this thread seems to be on-topic either, I've gotta ask . . .

Did Fender often mount electrolytics right next to (almost touching it seems) the power transformer?? Am I the only one who saw that and cringed?

Another thing I've always questioned about the construction of many (not just Fender) instrument amps is the practice of installing the chassis "upside down". I understand the design goals of allowing for a compact, single, chassis with the controls on top. But, every time the amp is set down (especially if it's hard, a common occurrence during load in/out ) it would tend to try to shake the tubes out of their sockets and most amps don't seem to use any tube retainers. The other issue is heat. Why would you mount an amp so that the maximum amount of heat from the tubes is absorbed by the chassis and, more importantly, by the parts inside? Lots of parts - especially carbon comp resistors - tend to drift in value and excessive heat only makes it worse. I know it's common for engineering decisions to be driven by low manufacturing cost, but still.
