  • Notes

  • This is the late version of Majestic model 71 from 1929 and later. See also the early version from 1928 with quite a different housing and chassis version 7A. We have found a picture of this later version as a low boy but are not sure if there is also a high boy with chassis version 7B - and vice versa. The difference can be seen on the plate: There you find the chassis Majestic 7, model 70 in the version 7A. This set and the early version have a push-pull output stage using two 171 power tubes. The Majestic 71 is made of walnut with burl walnut front panels and came with a Majestic electric power unit and Majestic dynamic power speaker.
