~10 1.5R 2W resistors to adjust voltage( C-R-C filter ), Mouser has 'em.
Two diodes, 5A min, 50V min PIV for full wave rectifier( CT is ground )
Mute switch, DPST, on-off of almost any AC rating will do, RS has 'em as well as Mouser.
Main off-on switch--same sources
Fuse and holder, fuse at ~1A, maybe less. Or start at a .25 slo-blo and work your way up.
If I forgot anything, ask 'em if you got 'em.
