Obsolete part

I was hoping a member of the forum has an old stock item

I have repaired it, but the printed circuit lifted a bit and the board is burnt where the space tag out came away from the board, there was a fault with these in the early days which was rectified later on with a modified housing to give better airflow, this is an early board, I have modified the housing to give more airflow, but I do not know how long the repair may hold, getting another power board is insurance against having to form out on a new oven as SWMBO wants a double oven which means altering the kitchen, ( less money for mens toys)
