so about 17w/ch
for 6BQ5 in PP. Separate PS in a console is somewhat unusual, it was found somewhat more often in early to mid '50s Hi-Fi components. Tend to prefer designs with the 5AR4, 5V4G, current draw has to be accounted for but with indirectly heated cathode as has about a 10 sec.delay so doesn't hit input and output tubes with full-on B+ the way a 5U4, 5R does, also produces surge on the filter caps. OK if the design properly takes all this into account, but like the slow warm up rectifiers. Full B+ can be potentially hard on expensive output tubes... don't want to blow those NOS $2500+ WE 300B tubes in some SET amps (not that I'd ever have one!)... thanks heavens you only need 2 tubes for stereo!
the C-M IS a very attractive cabinet design, very nice console indeed.
BTW the 2 amps in post #47 are out of tape recorders, not sure of the brand.
