Are you now getting a decent volume out of the player ?
If so, as Lawrence pointed out, you may need to make some final adjustment to the pre-amp gain to suit the now (hopefully!) properly working EL84. Ideally, find a record with lowish modulation (as quiet as you can find, usually something with a very long playing time) and then set the gain so that the player
just starts to distort (by ear, out of the speaker) at the maximum volume setting.
Ignore the clipping at the pre-amp output, it is always going to clip asymmetrically with a single ended amp
