Any idea where would be a good place to ask for a spice model of Dynaco Z565 output transformer?

According to the Transcendar site, its primary inductance is 100H at 120Hz, Rpri is 360 ohms. Its impedance ratings are 8k primary : 8, 16 ohm secondary. I can't find any other meaningful specs out there.

Sorry if this is off-topic for this thread. Mods please feel free to move or remove if appropriate.

Robert McLean posted a spreadsheet containing a number of transformer models here:

SPICE Transformer Model Spreadsheet

It doesn't include the Dynaco Z565 but there are instructions for creating models if you know certain parameters, primarily DC resistance values (which are easy to measure) and primary and secondary impedance ratings. Inductance values for the SPICE model are calculated.

Maybe this will help.
