TABLE OF CONTENTS Obtaining detailed valve data used to be extremely difficult, and the author considered himself to be very fortunate in having an almost complete set of Mullard valve data sheets. Fortunately, there are now many sources of valve data sheets, whether books or Internet sites.
Mikolajczyk Piotr and Paszkowski Bohdan (1994) Electronic Universal Vade-Mecum . 2nd ed. Wydawnictwa Naukowo-Techniczne. 659 pages.
This beautifully presented tome is a mine of information that allows you to compare types. It doesn t have quite the detail of an original manufacturer s data sheet, but it has most of the curves, so if you only buy one data book, then this is the one to buy. Distributed by Colomor and Hi-Fi World.
