I finely got my PT and OT 
but I am a little unsure of how to connect the OT..
My plane is to use one 6v6 tube with one 8ohm Celestion G12M speaker.
The OP have 5 taps at the primary and 4 at the Secondary.
The primary
3k….2.5k…(ct)…2.5k…3k
The secondary.
16ohm…8ohm…4ohm….0.
is there some one there can explain me how to connect the primary?
I expect that I just need to use the 8ohm and the 0 tab at the secondary?
Thanks Humle
