I have an open filter choke on my Philco 90. Where would be a place to get a new one if I need to go that route? I checked Mouser but I didn't see anything with the specs I need. Philco has it listed as p#4951... 4 Henries, 80ma and 150ohms. Not sure how close to these specs I need to be. For a used one, go to Oldradioparts.com?

Thanks, Don

Typically specs aren't real important. The inductance you can go higher but not lower same with the current. Resistance isn't very important. If you can stay within 100-150 ohms of original

Mouser has some.

http://www.mouser.com/ProductDetail/Hamm...61EBX0Y%3d

4H 90 ma 108 Ohm


http://www.mouser.com/ProductDetail/Hamm...WG9NZbQ%3d

4H 225mA 65 Ohm

Use either one, the first is cheaper.
