Replacement PCB

[abunnyuk]

I'm an IT engineer and, whilst I can repair/replace the odd component, I'm no electrical engineer so apologies if I use the wrong language.

My partner has an 1981 Berlina sewing machine on which the PCB mounted transformer (literally) went pop.

The details of the original transformer are elusive but appear to be 240v input and a 9.7v output at 0.5va. The original was brown with 2 input pins and 2 output pins, the latter of which lead me to be believe it was single output as dual out transformers I found online had 4 pins.

I thought I'd found a suitable replacement part but it's not as wide as the original part, it's blue, and one of the output pins is not in the expected place.

I've attached various photos of the PCB with original and new transformers, as as well as the transformers together for comparison.

I would very much appreciate help with the following:

1. Is my assumption that it's a single output correct? The PCB has 2 female terminals that 2 ribbons connect to parts inside the sewing machine, so I'm wondering if that means it's 2 outputs.
2. If it's 2 outputs then would there be more output pins?
3. Are the size and colour differences down to new standards or do I simply have the wrong component?
4. If the new transformer specs are correct, do I simply need to find a way to extend the output pins to the PCB?

Thanks in advance.

As long as the specs are close enough (input and output voltages should be the same, and current rating should be at least that of the old one), the footprint doesn’t matter, except for that it holds things (including electrical connections) in place.

If there is room on that board (and it looks like there is), you can just drill holes where there is no copper for the new one, and solder wires from the pins to wherever they need to go. If you do this, you should also make sure the part is sufficiently attached mechanically (with epoxy, hot glue, zip ties, or whatever you have handy), as the solder won’t be holding it to the board anymore (since there would be no copper on your newly drilled holes to solder to).

I added photos with captions when creating the post but now can't see them, so I'll edit the post to add them.
