I have a GROCO K model, 12 volt electric, head for sale. Two years old and in perfect working condition. Cosmetically looks like new. This head is sold by Defender Industries for $1200. I'd like to get about $400 for it but will consider reasonable offers. Contact me off line at <j.siegel at rcn.com> or 781-862-3519. JULES SIEGEL K42 #188 CARINA
