 VOX BIAS
I have recently acquired a 1965-66? Vox AC 50 Head  
(50 watt, 2 chnl., GZ34 rectifier, & EL34 power) Although I am very familiar with Fenders, I need a little help on this one. How do I properly bias the amp and what current should the El34s run?  
 
Thanks for any help.

The schematic says"Bias Setting-Adjust to give 2.2v across the 47 ohm cathode resistors in the EL34's" Never worked on one myself though.That's about 46ma per tube.Should be nice and warm.
