Hello, Information about the differences between a 506 and a 506K. I think that there are also two different sizes (height) but I don't know if there is any correlation between the size and the letter K. It's important for instance in the Philips 2514 model which needs the smaller (height) tube ! I also sent this info to the Tube page (Typical circuit).
Cordially. |

Hello Jean-Pierre The letter K stands for "kort" in the Dutch language, which means short. The right hand drawing of a "typical application" for the 506K is not correct! Kind regards. |
