Power transformer 4453A

Fred Schumacher

I recently got a 453A with a shorted power transformer. This short is at the primary side to earth.
As the technical manual does not specify the secondary voltages, I am looking for someone who can inform me about this.
I know the 435 and 454 have similar dc power circuitry connected to these transformers, so I wonder if a transformer from these scopes could be used. I noticed the cooling fan is connected to the secondary side as for the two other models, it is connected to the primary 115V side.
Any help would be appreciated.
Thanks in advance.
