I am not tapping the glass. It's the clicking sound emitting from the 6C33C tube as it heats up in the initial power up. Same clicking can be heard from the tube as it cools down.
The internal graphite structure of this tube is quite substantial and it has dual heater elements so it runs hot. It seems to me like the internal of the tube is laterally expanding as it heats up and retracting as it cools down.
