Hello Hakan,
It is definitely a professional installation. The fan assembly would have to be manufactured from scratch and the chassis rear plate would have to be manufactured from scratch. I did compare a known stock 602 chassis rear plate to my 602 chassis rear plate. They are very different.

Two questions about the Tek 602 display unit--
Does anyone know what the *Mod 174K* is?
My 602 has a Tek factory installed fan. Has anyone ever seen one like this and/or have the fan schematic?

602 mod 174K was a special CRT. As I interprete the info it came with
an internal graticule of a 8 x 10 cm border only and an external
8 x 10 graticule. Apparantly it was offered with four different
phosphor types were P31 was, or became, the same as opt2.
Can't find any info on the fan. Are you sure it was factory installed (by Tek) ?
