hello,

i own a fender red knob the twin (converted to top so the tube layout picture isn't in the cabinet any more) but i don't own a manual for one. i'm trying to find out in which sockets the 12at7 tubes go. There have to be 2 12at7 tubes in there but i only have 1 in mine. If someone owns one whould he or she please check for me. help would be much appreciated.

greetings,

Thomas
 
The 12AT7 is the phase inverter tube. There should only be one of them. It would be located closest to the power tubes - or furthest away from the side/end of the casing -(which would be the V1 socket).

Someone may have put more than one 12AT7 in there, but it should be all 12AX7's, which are all the preamp tubes.
