Nice collection of vintage equipment... thanks for posting! I could not help but notice that they appear to have taken some artistic "liberties" with the Safari chassis. What did they do, stick an old 2AP1 in the hole where the image from the 2EP4 normally appears?
The faceplate of the stock 2EP4 is flush with the top of the chassis, normally only the mirror assembly would be in the area above the top of the chassis, NOT the end of a CRT!
