Ah, yes. Triad. They seem pretty solid too. I wonder if an outfit like PREM Magnetics will make you a transformer.
Which explains the price.

They also don’t do custom winds. Their standard stuff is very customizable, though. And still waiting for the other shoe to drop on the impact of tariffs. So far prices have been steady.
Most of Triad’s stuff is made in China too. Their toroids are comparable to Anteks, prices lower in some cases higher in others. Their EI’s are ok quality wise, but performance leaves a lot to be desired. At 20% regulation typical, unloaded voltages can be crazy high. 6.3V ones I bought for heater supplies when doing tube prototypes ended up being almost useless. It was easier to add a 6.3V winding to one of their 115-0-115 toroids than to jack with dropping resistors.

DK red was the most expensive of options I explored for the 190sq cm board I referenced in my comments above.
I found this in India https://export.indiamart.com
It appears that toroids are on there. I found pictures of R-Cores etc.
