Well, the first thing is for Enzy to verify and confirm there's a center tap. If there is a center tape, I definitely go with dual 12V supplies instead of single supply. Capacitor is not a good thing, unless you use all film caps, they can introduce distortion.
As for me, I just use a +/-15V dual switching supply https://www.ebay.com/itm/hot-sales-dual-output-switching-power-supply-50W-15v-1-2a-15v-1-2a-D-50F15-/321574148358?hash=item4adf501906:g:6HcAAOSwxH1T9bDn
I always use SMPS if I can help it. I use this on both the preamp I designed and it work like a champ. Quiet, light and cheap. no big filter cap, just series output inductor and make sure have 1000uF on the preamp pcb. Save the trouble of rectifier, more filter, more wiring and all.
