As Terry stated schematic is wrong, radio must be correct or the 150ma 50L6(s) would have excessive heater voltage and other tubes with 300ma heaters just barely lighting. The late version shows 50A5 wired correctly.
Tube pin count is always clockwise from locater key(or space for miniature tubes).
There are two unused pins on 25Z6
