Triode:
Audio will ALWAYS generate noise in forums. In the the era, the better amps weighed more. Thus weight tending to symbolize quality.
If you want an amp to build, I'd suggest The Leech Amp. https://users.ece.gatech.edu/mleach/lowtim/ Ampzilla from Great American Sound was a nice amp in it day as well. There was a construction article in Radio Electronics. The GAS100 (rebranded) IC was a common one at the time
I chose to build a variation on the Leach Amp. Mistakes will really annoy you. It's dubbed as a Low TIM amplifier. Rise time and frequency response are off the charts.
To make it better, you will have to understand it.
The power supply suggested is lacking. Mine lacks a power switch. It runs cool. I would like to see clipping indicators over temp indicators and a power light.
I put effort into slow turn on-ramp up of audio and a 2RU form factor and easily serviced. My turn-on circuit could be better.
