Psvane Treasure 211-T
Psvane Treasure 211-T

    Improved structure over the old Shuguang 211 model for safe shipping, wider diameter (2 1/2″) for stability and quick heat dissipation, gold coated brass base to improve shielding to interference, gold coated pins to enhance connection over long term,All parts are selected to the highest grade plus only highly experienced workers to assemble, suggested burn-in time is 75 hours.

211-T is direct-heated type thorium tungsten cathode triode, can be used as class A, B and C.
