Description

Cossor 41-MTL, equivalent to Telefunken REN904. Really rare collectors tube!

This tube has seen some use but still tests with 75% of a new tube.  

The coating looks ok with some bigger stains and storage dirt but overall the coating is ok and does what it should. Please take a look at the pictures. The tube is in good working condition. 

This tube came from a closed down radio shop with many rare tubes from the 1930s. 

This is a very rare tube and a perfect fit for any serious pre-war tube collection….
