I think the advice that follows can avoid a few disasters!!

From a sound point of view, this attenuator is perfectly his office, however, in principle it is extremely dangerous to the output transformer of your ampli.l impedance input attenuator assembly + amp will depend on the race the knob on the box. Indeed, the attenuator is in fact (what a beautiful commercial scam by the way!) A simple voltage divider. Take the example of mounting 16 ohm to simplify (in fact it is 15 but hey ....), to zero, the impedance seen by the transformer is 16 ohm, one quarter of the race it goes to 15, half to 13 in three quarters to 11 and finally to full speed (do not forget that full race is not going to give in terms of power output to your HP as half the power delivered by the transo, which does a decrease of 3 dB noise as to be barely perceptible to the ear) it gives 8 which is half of the start and that is extremely detrimental to the transformer if it has its release scheduled for 16 ohm.
Parade: Never exceed one quarter of the race and then take exit 8 ohm of the amp, with the risk that the power loss (due to the fact that the 8 ohm output also corresponds to a voltage divider mounting!) not change too much the nature of sound. But this is by far the least risky
