please disregard pinout and octal/noval typesMaybe it's because you're using different valves than specified. The right ones aren't a fortune to buy.

I might be wrong but they look alike from the data sheet. Not identical, but close. Please, bear in mind that all voltages are spot on, as on the schematic with no gain reduction applied, apart from 6al5 generated CV.
