Field coil quandry
#23

Yes it seems correct if your numbers are right.
Has to be a fairly warm field coil with 10W dissipation.
The current seems a bit high, but even if it is 90mA it is still too high.

Your coil is the load type, not the filter type.
So look amongst the speakers whose coils are not part of filtering, but are loads on the B+, those are higher resistance and are likelier to fit your application.

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.
