Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

My current "Unit Under Test" doesn't do this

That does sound like a plausible explanation. I checked the HK A500 that happens to be on my bench at the moment, but was unable to detect any sign of this phenomenon. Maybe the relatively low Z of the voltage doubler and the bandwidth of the OPTs are factors. I'd like to find an amplifier that does this so I can confirm for myself that the cause lies with NFB functionality.
