Not specifically sure why you want to do the grid bias, but it surely can be done. You'll need to get higher voltage than the max by a decent amount and then get it lowered with resistors etc. Looking at the numbers I'd say shoot for -25V at the output of the rectification and then setup ...

WebOct 22, 2014 · EL84 is rated at 12W Plate dissipation. You have used the cathode current which is plate + screen current so you have calculated the plate + screen dissipation at 17W. The screen current will be about 1/5 of the cathode current. The plate dissipation is therefore 4/5 of 17W = 13.6W and the screen dissipation 3.4W.
