2.5 or perhaps 2 MH audio chokes New Old surplus still w/orig price tags ect – I think they were advertised as 2.5 millihenry. One of my testers says 2 MH and the other one 2.4 MH (for some reason). Laminated iron cores. I was thinking of using them in a Direct Conversion receiver (boat anchor style) to filter and demodulate RF into Audio but I didnt get around to it — Might also be of other uses. — price is $3.00 each plus postage– I can deliver to Sudbury area in early February my web site is easy to find under Netty Electronics – Im selling off surplus stuff as Iam closing out business except for crystal sales and some certain radio parts like FT301 parts and TS830, 530 parts and stuff like that..
