My first attempt with an RH type circuit was critiqued by the designer a long time ago.

All those posts are still in the archives.

More recently, I started looking at the RH type circuit again and tried G2 regulation with gas regulator tubes, but the distortion performance and noise was worse than my earlier/first attempt.

After that, I posted a thread that documented some circuit changes that reduced distortion by about 50%.
