Details:

That said, I made the determination to not hold onto them any longer. They re a really dynamic tube, they re just not for me. I recently installed them back in my to test them, they work perfectly, hold a rock-steady bias, and are totally noiseless. The KT77 Genalex Gold Lion Vacuum Tube is a matched quad with capacitance of 1.0 pF and heater current 1.4 A, operating at heater-cathode voltage 200 V.

There is plenty of life left in them. It has a screen dissipation of 6.0 W and plate 32 W, with transconductance 10.5 mA/V an amplification factor 11.5. With a plate resistance of 23 k and capacitance 9.0 pF, this new production vacuum tube is compatible with any brand model, making it valuable addition for vintage audio video equipment. I m pricing them to sell quickly.

The tube has a cathode current of 200 mA, grid voltage 220 V, and circuit resistance 0.5 M with fixed bias. They have been in storage for about four years.
