I was lucky enough to receive a Burning Amp Chassis. My particular piece has three rectangular outcroppings to serve as heatsinks on each side. Some versions had more heatsink pieces than this one.
My question is do folks know how much heat these chassis can dissipate with ~25 degree rise in temperature?
The chassis I received was incomplete, and I'd like to see if it's next on my work list for housing a J2 clone I'm finishing, or if I should put my efforts elsewhere for the J2 clone and come back to it another time.

AR2 put excessively dissipating Babelfish J2 in same chassis - fed with 24Vac Donuts and biased to 2A/channel
that was more than 200W overall
later - he removed one channel to second chassis , resulting in two monoblocks , but only because space didn't allowed use of 2 Donuts in one - one he put was too wimpy for both channels
but - he's having more 'sinking on sides ; see here ( in bunch of pics you'll find several of these cases ) : Vladimir’s (AR2) unauthorised strip blog …… by Mighty ZM | Zen Mod Blog
I hope you have few power resistors ( having 100W dissipation capacity)
then , all you need is variac and proper Donut and calculator , for dissipation test

One issue, the chassis in the picture you reference have 5 dissipators/side, I only have 3. If 200 watts was too much for those cases, I'll be out of luck for a J2.
maybe I didn't wrote clear enough - 200W++ wasn't too much for chasiss , but there wasn't enough place for two Donuts (while one was dying under load)
I hope you can easily find additional 2+2 pieces of rectangular outcroppings and mount them

make a test , and you'll know
I just found e-mail , where AR2 reported scorching around 150W of heat on one side only , for 30deg difference
