1. To get the membership
You can click here or click your language flag and then click "Sign in for MEMBERSHIP". Please read that text carefully.

2. To improve models and tubes
Members enter remarks or photos on the specific model page. Administrators will check before activating.

3. To add new models
Members add models by clicking "Create new entries" on the homepage. We are anxious to list all models in order to achieve a really complete catalog, like the one we have developed for the German-language countries and The Netherlands. There is very much to do ... Members and Administrators only can add/change to ensure good quality - but for the USA so far we often only show a grid ("bare bones") and good entries for some manufacturers like Zenith, Atwater Kent etc. Therefore we look for members who enter as free members (option 1) without any administration fee. 17 806 Members from more than 90 countries are active here. Please do contribute to our database or be active in the forum.
4. Contact as a guest
You can reach different teams via this contact form to provide us with your suggestions. You can also point out errors regarding programs, functionality, or poor translation.

Often we cannot help you immediately but we are eager to create and run good functionalities and data. We are interested in suggestions for improvements.
You also can send good photos of models listed or data and photos of yet unlisted models. At the moment we show 348 651 model pages.
Please tell us which name (and city) you would like to see as "By courtesy of ...".

If somebody only wants to know something about a set - for instance value of a set - we reply with this unless we may publish good photos and the model does not yet show any pictures.

You may reach the founder or administrator via the above contact form or if really necessary by postal mail (please note your eMail address for an answer):
