Sourcing a modern alternative for an isolating transformer

[Darren]

Forgive the slight lack of technical expertise in this question. I've recently bought an arcade cab that has a Hantarex 900e CRT, that uses an isolating transformer to provide a 120v and 128v supply to the monitor. I'm trying to replace a lot of the components with new parts, the JAMMA harness, controls, PSU are all being replaced, but the transformer is the trickest. This is the same as mine https://www.ebay.co.uk/itm/336624202742 however mine is pretty much in the same condition.

Has anyone replaced one of these with a modern alternative?

100va will suffice for 900e or 9000 or 9000a
The following looks acceptable

Really, i thought they were quite picky? Looking at the Data sheet, the 115v has a +- 15v variance that can be set. If I up the primary by 13v and plug the 120v into the secondary, would the CRT play nice?

The older Isolation transformers are typically a lot better than their modern counterparts.
Unless its needed for other reasons I would save the money and just check and clean the original.
Check that there is continuity between the 2 wires on each side and not continuity between the two sides. If that all checks out, give it a clean and it will likely last you forever.
I just pulled 4 from a bunch of cabs in am restoring and will reuse them because they will likely be better than anything I could get now.

I get mine from an Italian ebayer that makes custom/bespoke transformers. I ask for 128V output, 100W and they make it. Good prices too. Not sure this is an option for UK as shipping such a heavy item from Italy can't be very cheap but maybe there are similar sellers in the UK? Look for someone specialized in transformers not in arcade stuff.

I looked into that a while ago, but unless you're looking a batch, they are very expensive, for 1 or 2, through a company. Haven't come across any hobbyist types making them.

We have Airlink transformers here, they have made me a few transformers for recording studios, balanced rather than isolation not cheap but great products.

They make all types.
