have 450v across the el34s. plate to cathode. -39v across the 880 Ohm cathode resistors - so 44.3ma each side. 44.3ma x 450v = c. 20watts dissipation - so about 80% of recommended - quite hot but not crazy ? Anyway - like the sound of this amp quite a lot. Rgds Pete I run my EL34s in the JE labs 6S...
