Philco Vacuum Tube Tester Model # 7050

Here are the usage instructions, tube data, and schematic for this tube tester. They consist of small cards that are clipped into a two-ring binder in a compartment on the right side of the case. They were printed on both sides. This file has them printed on one side only. You could print them on the heaviest stock your printer can handle, and cut them to size, or glue them back to back if you have a glue that wouldn't wrinkle the paper. The file is an Adobe PDF file 10.4 Mb in size. DOWNLOAD FILE

If you want to just use this file on the computer and not print out the cards, use the PDF Bookmarks tab to quickly go to the page you want.
