Tube amp: Bring it back alive

I would definitely order two Hammonds (you'll need 125BSE, not 125B - please notice)


Hello all, i received my hammond 125BSE, how should i wire them to replace the audax?

Yellow and black to the speaker for the secondary i guess


But for the primary? On my old Audax there is one of the two cable (the red one) wich goes from an OT to the other OT
 
the connection between the two transformers is from the +supply, goes to the blue wire.
The brown one is for the anode EL84.
One of the speaker sides shout be grounded (black).
If there is a feedback and oscillation, invert blue/brown wires.
