Hi Robert,

Thanks for the information! We do have another way to show in which models a certain tube was employed: it's the automatic linking from the tube page to the model page as you can see for instance on the EM34 (very populated).

With sufficient data entered, that also gives you a good idea about the timespan of use of the tube in models. Of course tubes were available a lot longer as replacement parts and stock.

Can you create a new model entry for this device? Then the information is automatically displayed in the tube page here.

Thanks and best regards
Mark
