Transformer Core for Ultrasonic antifouling

[jonnybgood]

Hi,
I am building an ultrasonic antifouling circuit from this source: https://www.epemag3.com/proj/0912.html

The transformer seems to be a little difficult to buy. The exact one is a discontinued product:

Is there any place I can search for this core or maybe a good substitute?

thanks

The exact one is a discontinued product.

B.S. It's apparently discontinued at RS components, that's all. ETD29 F44 is still manufactured by MMG, and similar cores are availabe from all major ferrite manufacturers.

Discontinued stocks from RS are transferred to another sales company. I'm prohibited from telling you the company name but you should be able to trace it for yourself.
