I also have both Icom AG preamps U and V After blowing two in 3 months i finally ended up with the AG and they are still working after 2 
years now. As someone suggest it will be nice to have some figures to be able to have an idea of their performance.

I don't know how the others react but on my FT-847 i got an increased of 5 DB on the noise when i switched it on on VHF and nearly no 
signal increased on UHF but the amplification is there as when i got no signal at AOS without it and a S-1 to S-2 with the preamp is ON.?

Without the presence of a signal on UHF i cannot tell if the preamp is on or off just by looking at the meter and even when listening the 
noise i cannot tell if the preamp is switched on?
