Description: Up for sale, an early 7308 Amperex / Philips / Miniwatt SQ tube. This tube was made in Holland and has the early curved D-getter. These have been hunted to near extinction. The etched code is Delta 0 = which I believe indicates the year 1960. Printing still looks pretty good on the tube. This tube tests great on my Amplitrex tester and the sections are well balanced. 1. 141% emission / 116% Gm2. 141% emission / 114% Gm All tests are run in fixed bias mode which produces the most conservative numbers. I use regulated battery sine power @ 116.4 volts to avoid the inconsistent wall voltage. (test rig pictured) See pics, sorry no box. US bidders/buyers only please. This will ship tracked and insured.
