Default Help needed to setup 32 ohms at ESL63

Being at the stage of finalizing my older OTL / ESL63 project for the 32-ohms Quad ESL63 panel entry setup, I did some practical / non-critical determinations, but I would not need to do everything by the "ear". A comparative simulation of the original version (8 ohms) versus the 32-ohm design version at which the two input transformers have the primary series, is needed. There are some adaptation components, such as R1, R2, R15, C14 which, from the calculation, would give some theoretical value, but in practice, fitting better with other values. If I had these simulations with the related graphs, I could get better between what the ear says and what is happening in reality. To tell you the truce I am not practical with LT spice, that's why I'm asking for help.

Thank you in advance
