Reputable sources of isolation transformers for CRTs?

[framed_niner]

Hello. So seemingly everywhere I go suggests I purchase these from arcadepartsandrepair, but I received one that arrived damaged with obvious signs of use. This part failed after a couple weeks of intermittent use. Who sells these?

When you contacted them what did they say?

They have been a trusted vendor for a long time.

I would be interested to know the response.

They claimed that they never sell used parts. I responded with a picture of the obviously used item, they have yet to respond back. Here's hoping I won't have to file a charge back.
