FDP Forum / Miscellaneous and Non-Fender Topics / THD Hot Plate: Has anyone ever seen an actual schematic?

I have seen what I believe are authentic schematics for several attenuators, but never a Hot Plate.
The closest I have gotten is a THD Univalve schematic which claims to have a Hot Plate built in. In that case, it's basically a huge pot resistive type.

I have seen and/or have schematics for:
Dr Z Air Brake and Brake-Lite
Scholz Rockman Power Soak
Marshall Power Brake
Weber MASS and Mini MASS and Micro MASS and etc.
Weber 200 watt kit attenuator.

Thanks in advance.

I have an 8 ohm THD Hot Plate and it's great, but no schematic for it. I think THD mentioned it utilized a mixture of both resistive and inductive elements to achieve it's attenuation.

It has high and low tone compensation switches and uses light bulb elements as a noise reduction circuit, which is switchable in or out.

There are two speaker out jacks and a line out with it's own control.

I did some searching in my usual places but came up empty.
