Soviet IV-15 
Written by AnubisTTP on 2010-01-28  


The IV-15 is the Soviet analog of the popular 6977 / DM160 miniature tuning indicator tube. Like the 6977, the IV-15 does not have a variable length display; only the brightness can be changed. These tubes will illuminate nicely at 9VDC; filament voltage is 1.2VDC. Although the 25mm envelope height of the IV-15 is identical to that of the the 6977, the IV-15 has a substantially larger diameter. Nonetheless, it is still a very tiny device.
