I wondered if I could construct a similar circuit using my huge wirewound? I may be wrong, but from what I've seen of these, I think with the Brake Lite the chassis IS the heatsink, and it bolts hanging on the inside of the rear a combo amp, to dissapate the heat.

I built both an lite and airbrake... You can buy same parts and rather inexpensive. They sound pretty good

Could you please list all necessary parts numbers/articles for both? I'd like to build one myself
