Reel to Reel tape recorder

Hi, I have a Sierra / Pye 9123 model Reel to Reel tape recorder. There's a mains voltage switch (grey, circular, on the left in photo) with 4 positions (from 110v to 220v).

Hi, I have a Sierra / Pye 9123 model Reel to Reel tape recorder. There's a mains voltage switch (grey, circular, on the left in photo) with 4 positions (from 110v to 220v). The switch was inadvertently set to 110V when the machine was last powered up resulting in smoke emanating from the area where in the first of two transformers is located. The switch was reset to 220V. but the machine won't power up, Please see the attached photo. The transformer on the left is the first encountered after the Voltage variation switch. The second transformer is off to the (bottom) right in the photo.

Question: What is the likelihood that replacing just the first transformer could fix the machine? If so, would it be possible to source a replacement (the machine dates from the early 70s.) ? If not, would bypassing the first transformer and permanently setting the switch to 220V , or removing it solve the problem. A photograph of the wiring scheme is also attached.

Is it possible that damage would be much more extensive than just the first transformer?

Any assistance would be appreciated
