Choke selection help

Post by cpk313 »

I am building a 15w matchless based amp, 2 channel, one spitfire, one nighthawk. I have a Hammond 159P already ordered BUT I found this:

https://www.rfparts.com/20c54.html

$20 seems like a steal for that choke. The two are very close in spec 8H 150mA for the Thordarson and 10H 125mA for the Hammond. Hammond is open, the Thor is a bit prettier. I am trying to have this be a really high spec/top of the line build.

Opinions please

Thanks!!

One is 145ohms, the other is 155 ohms, I'm going to just stick with the hammond since it's already ordered and on its way. I can make things more complicated then I need to at times
