[Penthode]

Removed the convergence transformer this afternoon and the laminations this evening.

My recipe was to bake the can in a foil pan with the transformer can opening facing downwards at 400 degrees F for 20 minutes. The pitch dripped in a pool at the bottom of the pan. Then lifted the transformer can and the transformer could be removed. Placed the transformer in a second pan and baked it another 10 minutes to remove excess pitch.

I then removed the transformer wiped it down when hot and let it sit until warm. Then washed it in varsol until clean.

After it was dry, the transformer when back into the oven at 400 degrees for 10 minutes to again heat the remaining pitch. Then while hot, sat the transformer on the open jaws of a vice and tapped out the laminations. The laminations came out quite easily when warm.

The open winding was the focus voltage secondary input. I found the wire to the open winding is the outer most winding which should raise the chances of success repairing it as it will only require the opening the attachment of the outer most winding.
