Yes, that's right Larry. As far as I am aware Brook was the only manufacturer (or at least the only USA manufacturer) of directly heated triode audio amplifiers intended for use in the home (the Western Electric/Northern Electric products being theatre-oriented, of course) prior to the resurgence of interest in such things in the last few decades (and subsequent to the 1930's when companies such as E. H. Scott and McMurdo Silver offered certain high end multi-chassis "radios" which used 2A3 power tubes).
I had a Brooks (not Brook) mono FM tuner ca. 1954 for a while during the 1990's. A reasonably nice unit of its kind, which I think I sold for something like $50. In contrast, I suspect that a nice pair of top-of-the-line Brook 10C monoblocks (which as you no doubt realize were supplied with a choice of 2A3 or 300B power tubes, in a push-pull configuration) would go for well upwards of $20K today. It wasn't cheap in its day, either, selling for $315 (list price $525) according to a 1951 Allied Radio catalog I have.
