REPLY:
In terms of the device itself, that day is already here. The LDMOS
devices from NXP are fully capable of replacing tubes in a legal limit
amp and the price already beats tubes too. A pair of them that easily
puts out 1500 watts is around $400. Compare that to an 8877.
You can be sure designers are working hard to build the circuitry
around them that will soon make tubes pretty much obsolete.
FlexRadio already has a legal limit amp that is awaiting FCC approval
using said devices and they expect approval before the end of the
year.
As with everything, time will tell.
