7788, gain/noise/bias vise, as a penthod, is pretty much idle first stage for not-extra-stages low input preamps. (Phono, Mic etc…)

It is very stable by parameters . I have many of them, from different brands, and all of them are identically good. You can take any two of then drop replace and see that gain, nose will be the same and event a plate voltage will drift with no more then 1-5V (I drive them at 150V). 7788 has very neutral sound, not “sticky”, not “glossy” and not “showy”. It might be at “too fast” side if not properly used, but it is only if not properly used. All together it is a phenomenal thing.
