TO-92 may take the dissipation in this SSHV1 bias rather well -not in SSHV2-, 2SA1381 or KSA1381 for sure, its listed as SA1381 in German shops maybe because its printed so on its body if you look.

They won't work in high voltage ratings the pots, they are nested in low voltage areas. 0.5W Bourns multiturn will do.

20V for safety regarding mains change or trafo tolerances.
