Check the listing for details. FEEDBACK ECC186 ELECTRONIC CIRCUIT CONSTRUCTOR. READ!!!!!. Condition: Used. Listed at 90.00 USD. READ ALL. ECC186 electronic circuit constructor. I have half dozen of these selling one at a time. The last 3 pictures include a few drawers of parts I got with these at an auction held by a local power/telephone company. I will be splitting up the parts into 6 equal piles and including a pile with the circuit constructor board. There is diodes, switches, cables etc in the drawers. I am selling these as it with no guarantees that any of it works but they were obviously using them somehow before they sold them. Just not sure how long ago that was. See pictures and ask any questions. Thank you LOWER 48 SHIPPING ONLY. WE USE THE GLOBAL SHIPPING CENTER AND OVERSEAS BUYERS ARE WELCOME AS THE ITEM SHIPS TO THE US BEFORE HEADING TO YOU.
