Hi, Today I have completed the wiring of my m15mk1, the first test I have done has been the control of the tensions, which has been right ; moreover I have control the tension on the valves sockets and I have found that the primary of the OT 6-7 / 13 is interrupted. the ot is the ATRA0427. at this point what shall I do? May I use as primary pins 9 and 10, instead of 12/13 of the OT (which has resistance continuity) ? Or should I ask for a new transformer? In that case is there any guarantee?
thank you
