I got this to use as an output tube to replace the 12AU7 in my homebrew FireFly amp -- I guess it should be called a DragonFly now. Anyways, it provides the perfect balance of volume vs. gain in my little amp. The tube placement is as follows: 12AU7 preamp > 5751 boost (switchable) > ECC99 output power. Super clean w/ tele (no boost) and as dirty as you want with the 5751 switched on. Best sounding amp I've ever owned thanks to the ECC99!!
