What are these?
Every once in a while you need to do something different so I spun these upon request for a friend. Some of you might be saying crossover inductors, others that know me better may be thinking super tweeter field coil or cartridge electromagnet. Maybe showing the rest of the parts will let you in on the secret.
All joking aside, here they are assembled and ready to be installed under the cathode of a filament biased 104D.
We should be able to listen to them this weekend in the land of walter and I will report back. With an amp of current they drop 6.2V and hit a whopping temperature of 170F. Funny thing is the first pair got so hot the bondcoat on the wire cut loose which is why a bit of aluminum and brass heatsinking was used.
