6bm8/ecl82 is a dual-section tube with a separate triode & power pentode within the same bottle. 12xx7's are dual-section too, with 2 separate triodes in the same bottle. Discover tube pin-outs at the link below. Now, you can draw your own schematic from observation if none is found on-line or in your public Library. As already mentioned, the 6bm8 triode section likely is a driver for it's pentode section, & the 12xx7's provide pre-amp gain stages. My stereo 6gw8/ecl86 (cousin to the 6bm8) uses 4 such tubes with the triode sections providing driver & splitter for the push-pull pentode output.
