Hello all
I just noticed the choke that came with my OTS FM50 ( 50 Watt ) says 100 Watt on it.
Does this matter since this is just an inductor?
Thanks for any replies, I dont want to bug Nik every time I have a question if I dont have to.

I'm pretty sure you want it to be rated well within the potential of the amp. So no I believe this is correct. My HRM 50 has the same choke.

Thanks Soundperf
I figured if the watt rating was over the amps watts it would be fine, just wasnt sure.
One thing I noticed when on mercury magnetics site, is they only have 1 choke and it says its for the OTS50 but yet they have OT's and PT's for both 50 and 100 Watts but hey Im just a newbie who wants to make sure there is absolutely no smoke on startup.
By the way how is your build going so far, I think you said this is your first build as well right?

Well, you're sort of confusing the function of a choke vs. a transformer. With transformers you're typically stepping up or down voltage. In our case stepping up the voltage a good bit. Mainly the reason there is a distinction made with transformers is that a 100 watt will have a slightly different construction needs than the 50 watt. And the cost will be more. Most of the time anyway. I'm no electro-magnetics expert by any stretch.

The chokes are for filtering and it's probably just a expensive to make a choke that can handle 50 watts as it is 100 watts.
