SRPP stage useing a 5670

Post by acorn » Sat Oct 06, 2018 3:38 pm

Good day all

What is the advantage of useing a SRPP input stage as apposed to a normal input stage
would it be a better frequency response and lower distortion figures ? or are there any better
circuits out there I could use.

I'd forgotten what SRPP is, so Googled - ah yes ...

This may, or may not, help:

I would have used it for the upper valve being more like a constant current source, rather than a resistor,so therefore should be more linear, but having read a bit of the above I'm not sure now :shock:
