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?
