SRPP (something like in the world of vacuum tubes) in solid state audio aplications

[audiopro]

I dug this up after seeing this thread.
Any opinions on the circuit? Anyway to get the gain down without using global feedback?

I think this has been asked before, but isn't an Aleph some kind of SRPP?

I would say an Aleph is a variation on an SRPP. Same basic
principle, different circuit.

Thank you for the precision, Mr Pass

But I still haven't found a definition (or better, an article) that explains what a SRPP is.

Newer saw this. I think, it's something more sophisticated than this with 1k & 1k in SRPP like upstairs. The basic circuit isn't the best choice ...

Go to www.tubecad.com for papers on SRPP.

Kicking a dead thread, Stee? Why not!

SRPP can work for bipolars as well. Here's something I was playing with in the sim awhile ago.

The idea was to do something like the 1969 JLH, but with a better ratio of output current to idling current.

Series Regulated Push Pull.

Voltage across a sensing resistor in the middle is held to a constant.
In so doing, the upper end learns how much and when to pull up.

Search for "JFET SRPP" on this site, and you'll find a few things.

I'm searching a good method to split hot and cold
from unbalanced signal

Dear members of diyaudio.com

Do you ever think about SRPP in solid state audio (preamp and driver) applications?

Something like on the link http://www.hiendfi.com/modules.php?name=News&file=article&sid=102 ?

SRPP is often part of some super triod amp. construction

But in solid state World? Have you any experience with?

I use an tube SRPP front end on my hybrid tube/MOSFET amp.
It sounds very clean.
