possible pig ballasts on ebay
Original poster: "Fred Bultman by way of Terry Fritz <twftesla-at-qwest-dot-net>" <royaloakmin-at-home-dot-com>
Hi everyone,
While surfing e-bay I found these inductors:
<http://cgi.ebay-dot-com/aw-cgi/eBayISAPI.dll?ViewItem&item=1638854592>http://c
gi.ebay-dot-com/aw-cgi/eBayISAPI.dll?ViewItem&item=1638854592.
Does anyone know if they would work for a pig or what current flow 200
microhenrys relates to?
Thanks,
Jim Bultman
