For now, this is just information from the official MHDT page.
The burn in time will takes about 1 days for components and about one month for tube.The tube will be a big issue in this process. The installed tube GE 5670, date coded 1987, is the last generation of western industry, the golden tube ages. In fact is a good tube but need quite a long time to burn in and aging. The famous tube are all about 1950s’ tube as they were well aging already just need burn in.
The tube, I will not recommend any since it depends majorly in taste. However, I will say that the western tubes are quite good due to their materials used in making tube and not recommend recent produced tube like Russian or Chinese 6N3 due to wrong materials are used.
