Bush TV24C

Hi,
I saw a picture of an amateur TV from the 1940's that does not include an EHT tube rectifier. However, I noticed that an extensive selenium rectifier was installed. Were there serially produced TV sets incorporating such solutions during this period? I assume that the selenium rectifier could have been fitted at a later date.

That was the ViewMaster TV.  This was a TV receiver designed for home construction. The EHT rectifier was a selenium device although an EY51 could be fitted instead if desired.
The boost diode was also selenium with no provision to fit a valve.
The pictures are of a ViewMaster I acquired in 2016. it has since been fully restored.
