From an estate sale is nice un-built linear amplifier kit Ramsey. Its for qrp use, with 1-2 watts drive should give you 20 out. Since its in its original package which doesn't show any signs of having been open, I have to assume all the parts are there. Third picture gives the specs for this kit.
Since I can't confirm that its all there, it is being sold as.
