125B or 125C, both would do. Same price. 125B is a bit smaller: see the mechanicals.

You need that.
Do not get 125CSE - it is for Class A single-ended amps.


If you want an inductor for the filter, you could use this:

154E by Hammond
https://www.mouser.com/ProductDetail/Ham...zf6Q%3D%3D

It is small.
If you find out there is no space, use a resistor.
I do not know what the resistance of the 1st field coil. I doubt it was 3.2kOhm as the other shown in the sch, but the DC resistance of the 154E is 1.67kOhm and you could add a small 1W resistor in series if you need to meet the higher resistance number.



PS. Do not take it as "buy" directive, do some research first. I only gave you some general pointers.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
