Hello everyone. I am new on this forum. I am looking for a schematic and technical information about a Prisma 91 TV set from the 1950s.
Thank you
Adam

Hello Adam,
Have not found a schematic but here a few sites with information for the prisma factory in Antwerp.

Thank you for the information. As I see TV Prisma 91 is a very rare model. The documentation on it is very poor.

The PRISMA 91 consisted of 3 models like the photo.

Such valves were used in TV Prisma. Maybe a similar circuit has some other more popular receiver, e.g. Philips.

Prisma engineers patented the 625/819 automatic switching. Patent number: 551.861 and 553.868. Where can I find more information?

Hoi Adam!
I have a schematic, too and a USER-MANUAL!
I own the console with the big speaker!
I am always short in time to do scan jobs.
Regards,
Adelbert
