Re: Recommend a bright, low-noise 12AX7
Not sure where I read about that flash but it’s a thing those tubes do. NOS Mullards as well.
Mine all do a weird flash when you power them up. Like a light bulb blowing, but just for a second. Scared the crap out of me the first time I started up my amp in a dark room (thought something caught fire or burned out) but they seemed to work fine afterwards.
