ESR B1000 output transformer questions

i've have my B1000 for a while now and i assumed the output impedance is 8Ω, but after 3 days of searching and asking a few questions it seems like the output impedance is probably 4Ω. i'm also guessing that if it was that important ESR would have labeled the jacks...i opened the amp up and noticed an unused yellow lead coming from the output transformer. any ideas on what how many ohms that tap would be for?

i figured it was finally time for me to join the one site i should've joined the day i got the amp...Thanks for any help/info you're able to give.
