Visitron phototube

Postby McGee2021 » Sat Jul 30, 2016 4:06 pm

I recently purchased a photo-tube on eBay that i think i read of in the corona spark television article from the 1920's. I was the only one to bid on it, and i think i stole it at a price of $5 USD. It has ratings engraved on the side, and markings that tell which pins are positive and negative. It is actually quite large, and has a large sensitive area for direct placement behind an early non-flying spot camera disc.

You may or may not be able to see the images. They also may take a bit to load. I'm trying something different :lol:

Here is a link to another type of visitron, that appears to be the picture of a tube on the carton.

Nope, none of the images loaded, nor is there the usual download link for large images that won't fit your screen within the board window.

They need to be of a type whose extension is allowed on the board, the following image types are accepted, gif, jpg, jpeg, png, tga and tif. It may also be a function of your browser, though I would think all can accept that list.
