You can use Phenidone, Phenidone B, or Dimezone in place of Dimezone
S. Substitution by weight for weight is good enough.

If you can't find triethanolamine, some modification is needed to
adjust the pH, because it is a part of the pH buffer. Among off shelf
products, I'd say XTOL 1+1 or 1+2 and Technidol are worth trying. But
a lot of people seem to have troubles with Technidol.
