Tube Data Sheet Locator Personal edition (TDSL), that's the full name of the program, which contains data on more than 19,000 tubes. Written and compiled by Duncan Munro with assistance from Steve Bench. It is distributed as a fully functional trial version. However, the upgrade with new data is paid and costs .95.
TDSL runs on any PC with W95, W98 or NT. It "bites off" a little bit on the hard drive, about 1 MB.
After launch, you will be greeted with the main screen of the program. In the left part of "Filter" there is a list of tubes according to the search result, in the larger, right part of the screen there are data. Socket wiring, known substitutes, limit values, operating values and lines are available.
Although the database contains data on more than 19,000 tubes, the vast majority do not contain all the data. Specifically, socket connection 4386 (23%), known substitutes 8579 (45%), limit and operational values about 2800 (15%) and lines 13,274 (69.7%). So at least something about each tube. Those who have access to the Internet will not have problems, because they can search for data through the links in the program. Of course, after paying for the upgrade, the database is more detailed.
The most important function is search. TDSL searches in two ways. The first is search by type. Just enter part of the type (e.g. EF) and then select the required lamp from the list. The second search method focuses on parameters. The requirements are defined (e.g. Ua>1000V and Ia>0.5A) and the program searches for all tubes that meet these requirements.
Starý dobrý Příruční katalog elektronek TESLA tento program nenahradí. Veľkú väčšinu elektrónok som v ňom však našiel. Je samozrejmé, že v prvom rade záleží na obsažnosti databáze. V budúcnosti sa iste bude rozširovať, preto vidím jeho šancu na úspech. Celkovo hodnotím známkou dva.
