UO-186 Triode

The UO-186 is a glass envelope power triode having a plate dissipation rating of 15 Watts with convection cooling. It is intended for audio frequency power amplification service in triode connection and single or push-pull/parallel applications. The UO-186 has an directly-heated oxide cathode. This triode has audiophiles deserved love because of high linearity characteristic.
