Hey,
Anyone tried designing a preamp/distortion box using a 12sx7 with a lower voltage Power Supply?
The attached RCA data sheet shows load lines for 0 to 50 VDC.
Thanks in advance

Datasheet says it works up to 300V. Operation at 90V seems to be the same as the 6SN7, it also says curves under type 6J5 and 6SN7-GT also apply to each unit of the 12SX7-GT. So it is a 12SN7 tube, gain of 20. Checking the curve at 50V for the 6SN7 it is the same as the 12SX7. I think they are more or less the same tube. Now if they had double the gain...

It's just the good-old General Purpose Triode, 6J5, doubled-up, made very well, processed for low-volt aircraft work. It sells for $50 and up and up.
Voltage is your FRIEND. Just not friendly to fingers and heart. It is like working with saws or snakes, except you can't see voltage. Keep your head clear, also your fingers.
