Well, to be fair, the topic has been discussed quite frequently around here after Dave did a video on his simple constant current design...  I'm sure the search box will turn up a few examples if that video isn't floating your boat.

Not sure what you mean. I use a cheap adjustable Rheostat which I got from ebay.

Thank you beljemmett for pointing me in the right direction.

Since you obviously still don't get it:

What frequency, or is it for DC?
What wattage?
What impedance?

Or if you can't answer that, what are you going to do with it?

And why you didn't ask that on the first place ?

Please do not make this forum a pathetic thing.

Yes, we need more information...

As you can see, I did that in my first post already.
I really wish that people would think before posting questions, it's like asking for a lamp or a battery or a resistor... oh wait.

i have that at work, the mechanical section would phone and say something like, can you bring down a power lead for this box, I’d reply, only if you bring up a nut for this bolt  :-DD

Um, that could have gone better all round...  :(

Okay it was very short on technical basics, e.g.

1. Audio or Radio Frequency load ?

2. Impedance required ? but could have been surmised from AF or RF.

3. Max working Wattage ?

With the above, I expect you would have been given an answer... however, we all learn by experience and help; it's the box of sparks syndrome.
