hi all,
Is there a schematic for single ended Class A with dual supply rails?.
Let me know.
Thanks

One of the most popular is the AlephX. You really have to come over to passlabs forum. :)

| Or stay here and look at the Krell Clone thread. It's not single ended but it is a cracking amp. ;) |

And let's not forget the Alephs on the passlabs site.

I forgot to metion i need a circuit based on bjt single ended with dual power supply rails.
PAsslabs are FET based. |

on one of the passlabs sites is a project from 1977 that sounds like it matches your needs. it's an project from the now defunct "Audio" magazine. the entire article is available as a pdf.

How about the A25 on the passdiy site then.

That is diffrential input stage not single ended. :@
It seems like no one has buit an single ended class A amp with dual rails without feedback. |

Hi boxedin,
In my view, a single ended amplifier refers to the output stage. I realize that others may hold a differing view.
I consider the A25 to be a single ended class-A BJT amplifier. I can't think of another recommendation offhand but there must be one.
I think you may have to design up something for yourself. How about grafting the front end of the JLH onto the output stage of the A25?
Regards,
Graeme |
