Got my kit last week and my wife wrapped it for Christmas, unopened. Now I am checking all the parts against the list and I am missing the 4 220 ohm 1/4W carbon comp resistors. They are checked off on the checklist but I cannot find them. Is there anything special about these resistors or can I get any with the proper specs to replace these, so that I would not have to wait for Bottlehead to ship them out? Thanks for the help guys.
