Hi all - I took the first voltages in my new 300B amps. Both amps gave the same voltages. All checked out except for ---

       manual     my reading
T4      71          Not connected
T5       71          73.3
T6       0            73.3

I assume the T4 is a typo, but I'm worried about T6; when I looked at the manual for T6 for the soft start modification, it also reads 0 at T6. Is this also a typo, or is there a miswire in both of my amps?

thanks in advance for everyone's help - I am almost there!

I see that in the V1.0 manual, it's definitely a typo.  T6 should be the same as pins 1/4 on the 4 pin socket.
