Yes I'd go for an EZ81: it ws used in loads of 50s/60s stereo radiograms to provide HT to a pair of single-ended EL84 alongside [typically] an ECC82 double-triode audio-amp, an EABC80 detector, EF89 IF amp, ECH81 frequency-changer and ECC85 FM front-end. Add in an EM84 magic-eye for an extra few milliamps and the trusty EZ81 still wouldn't worry.

I'd happily use an EZ81 to power a pair of EL84 and some trivial milliamps for the low-level audio stages.
