Should headphones be plugged in when tube headphone amp is on?
Like the title says... I'm picking up a used Feliks Euforia headphone amp and was wondering if headphone amps were required to see a load when powered on like tube speaker amps do.
i would assume that it is the same as with tube speaker's amps - it has to be connected to load. Open output in tube amps can result in damage to output transformer (overvoltage).
