 Quick update. I measured voltage some GI globes on the Tom and got 7.8vac. I would have expected 6.8v there abouts ???

Could this explain the cooking? And where do I look now? Thanks

Also just went to remove the pcb and found J121-7 fully burnt header and connector pins. So this explains the out GI's but not why they keep burning.
