Amp works fine. I have used different cap values but 100mf sounds better to my ears.
I have also added 22mf betwwen Vout (pin 2) to ground, the soundstage seems to be scaled down.

I am confused about your suggestions to run the El84 at 104ma using a 12R resistor
When u feed more current . First the vocal sound thicker. Than u have better soundstage. Get rid of the 22mf in pin 2 not required it will create different sound, best if we do not use caps at all but cant help it as we need it here & there .I have tried it with value from 65 - 100ma and i think it sound best at 100ma.
