How to search and insert Model Identification.

For reason of capacity we have set up 3 fields.


1. Model-Name (and Numbers)


If there are, we prefer real names- also a brand if different from the manufacturer name, followed by the alpha-numeric codes. Also several names are possible.

2. Model-Number (Chassis)

Numbers we normally would place into the number- field. However, for US- models we normally would identify the chassis- with “Ch=” ahead.

In the past we used to repeat terms in brackets, especially when we had combinations of names and numbers-so that search engines could find them . This we won't do any longer, since the the search- engines are now more “intelligent”.

3. Field Variant

This field only will contain information, if the exact same model name was used for a different model of the same manufacturer or for a variant of the same name.

Colors and type of wood we only distinguish if other parameters also change, at least the price of the model.

Example for variants (should be brief): old / new or EM34 / EM80 or 1962 / 1965. (Could be seen as a descriptive term).

 How to search

For models we offer four different search- procedures:


  1. Simple search

  2. Search with limits: Model-Type, Country, Brand / Manufacturer, Time-Period and special limitations with “only if”: Pictures, Collector-Prices, Diagram, Transistor Radio.

  3. Professional search – with about 30 Criteria.

  4. Search for tubes / valves or semiconductors.


Try to use the simple search, unless you get too many results. After that try to limit your search with “Advanced Search for Antique Radios etc”. More for 'statistic' research the “professional Search” would be used- which is available to members.

In case you won't find a diagram for a model, a search via set of tubes or transistors could offer some help. The resulting list you can switch to show models with pictures and back again- you also can sort the lists with different criteria.

You find models also through the link "Country/Brand", by selecting the country and clicking on a number (count of manufacturers), selecting the manufacturer and have the results sorted according your needs. If you are looking for diagrams, the link "Schematic Finder" will provide an answer.


How does the search work?

The system will combine both fields and compare with the human input, if some of all is matching up. With “Exact search” it only will look for identical single terms.

It is normally not practicable because of the terms in brackets. The "Advanced search for ..." offers a check field "skip maker list if possible". Please try it out if you use this search. The manufacturer Philips would be a good example for such attempts. Generally: Shorten your search term if you don't get results. Special characters like /, -, (), " etc. are first stripped by the system - don't use them for an easier search.


Search-Rule from the blue Info-Buttons: Try using only the number within letter / number combinations- by that you will find the “whole family”.

If you try the same with a search- engine like Google, the result will be different.

Example: TK23A; if you “Google” this with three separate terms as in TK, 23 and the letter A … you will be lost. Therefore we combine all parts to one term – unless there is a dash as part of the identification. In this case both can be found as one term and also as separate terms by the newer search engines.
