I believe most want to know if this rebuild is still under vacuum.
Has the rebuild been installed into a working set? Is it used? That is, is it powered up and watched regularly? Has the tube been allowed to reach operating temperature and then powered off/turned back on? Has the tube spent its rebuilt life in a shipping container stored in an essentially constant temperature environment?
