What I like about it is that it's a drop-in replacement for a 12AU7. Thus you can quickly supercharge any vintage piece that uses 12AU7 either as a CF or in a gain stage, without re-wiring the socket. Of course, the PS has to be able to make the extra filament current and the B+ current needed to make the ECC99 sound its best. I also use it in cascode as a CCS in my preamplifier, which has a -250V supply.
