this its a wonderfull triode for audio, win the ETF 2018 shootout indeed
every year if not used should be heathed few hours for gas free
no getter triode
for old stock tubes should be warmed few days , then put grid and plate toghether
and let plate current flow starting by low voltage like 40volts till max plate current
afther you can put HV

hello friends!

the TL series or vt-127a, with its low gain and low impedance plates, gives the opportunity to swing to class A, with a negative bias.
Mode 1000-1200 volts, 50-70 mA, -25v on the control grid.
Yes, it is a low power, high impedance output transformer, but any the most beautifully singing driver through a 1: 1 interstage transformer, and great pleasure on high sensitivity acoustics
