Tube socket PL7-2K-E46 (ПЛ7-2К-Э46) is a 7-pin metal-ceramic tube socket with aluminium shield (H = 46 mm). This tube socket is ideal for tubes with general height ~ 46 mm (measured from the bottom of the pins to the tip of the glass envelope). It is suitable for tubes like 6J1P-EV (6Ж1П-EB), 6J1 (China), 6F32 (Tesla), 6J2P (6Ж2П), 6AK5, EF95 and many others.
