Diodes and Power Supply Modeling in LTSpice

Hit me I might be being too literal and LTSpice doesn't "see" any differences in diode specifications, since does not allow them to be installed under components.

I modeled this: http://www.r-type.org/addtext/add158.htm (sans transformer since seems redundant and no pots since not an option in LTSpice), surprisingly got no errors and getting voltage, however, I don't know how to write and/or set up input voltage so getting way too low of a voltage out of HT (a few volts when probed).

Does anyone know how to set up an input for a power supply?

If not, fine, I now see my new assumption about diodes is correct, to LTSpice all the same. Plus, succeeded in creating a model 95 percent from scratch (copied the scripts @jcalvarez provided in another model). Though be nice to get it working, like to probe around and gain more understanding of circuits.

Thanks in advance! 😀
