Default Balanced circuit topology

Hello,

The Glowmaster from SAC has received good reviews.
Are there any other designs with true balanced circuit topology from input to output stage which is good?
It would be an interesting diy project but I have not found any information about this kind of design.

Try searching for Vacuum State or Allen Wright.

A circlotron with balanced input would be an example, I suppose?

first define your goals, is it for powering a speaker?

The SAC Glowmaster appears to an amplifier. I believe Lynn Olsen is a DIYA member:

The Amity, Raven, and Aurora
The Karna Amplifier

Preferred characteristics:

Deliver high current to have a dynamic and controlled bas
Low distortion, wideband
Linear Class A
26 dB gain
No feed back

Good to have:
Balanced input XLR or RCA
Auto bias
Balanced output

A good question would be what in your view constitutes a balanced output.

60W with no global feedback and low distortion...not easy.

He said, 'no feedback', not anything about global, Schade or what ever. There was no definition of 'low distortion' either...LOL

There is also no requirement for output Z...
cheers,
