[QUOTE="El Sid, post: 959946, member: 18550"] Yes the artificial centre tap is exactly how it's done in my Mars EL84, except the tap goes to the cathode of one of the EL84s so the heaters are raised a bit. If there is a problem with hum, then splitting the heater and circuit ground then implementing a hum trimpot will be one of the first things I do. [/QUOTE]
