Simple question for Mr Cavalli (or others if they are 100% positive of the answer):
Does this amp require 'warm up' time after power on because of the tube? If so, how much, and is there some kind of relay or whatever for the tube warmup?

Tubes require about 20-30s to warmup. Some faster.
The CTH has a protection circuit that keeps the headphones disconnected until warmup period is over and if the average DC voltages at the two outputs are low and safe.
This is indicated on the front panel with a single LED that is red during startup or fault condition and white when everything ok.
