I just wish I had some original 12AX7s.


You probably know this already, but keep a look out for an ECC83. That was the British/Mullard code for the 12AX7.

I still use a Vibrator transformer, most for fun, but I have an old electromechanical telephone exchange in working order. It has 2 set of vibrators for ringing current approx 25Hz 70V and a sound generator making a buzzing dial tone. In case of problems it has a reduendancy vibrator for each.

I haven't seen one of them since I played with car radios that had tubes in them. It was really just a Fred Flintstone switcher power supply.
