Valve Equivalents

This is a table of equivalents based on data given by the manufacturers. Valves specified in the first two columns may be replaced by those specified in the the fourth and fifth columns. The reverse is not necessarily so, it may work, the pin out will be correct, but ratings may be exceeded in some applications or other characteristics may cause problems. Specific searching is best carried out by Edit->Find in This Page followed by typing in the number of the valve concerned. I hope to have search facilities available in due course.

Valve image indicates a link to a web page with photographs.

PDF logo indicates a link to a PDF data sheet

The characters below will lead to the beginning of that section of the table.
